*VIDEO* Congratulations To Danny Calaug For His First Professional Gold Medal!

Check Out Our Video About Danny!

"MANILA, Philippines - Daniel Caluag finally won a big one as a Philippine athlete as he bagged the gold medal in the eighth Asian BMX Cycling Championships in Singapore last Sunday.

Caluag, a 26-year-old Fil-Am whose parents are from Bataan and Baguio City, clocked 29.951 seconds in winning the men’s elite gold medal.

Caluag, a veteran of the London 2012 Olympics, beat two Japanese stalwarts – Tatsumi Matsushita (silver, 30.306) and Jukia Yoshimura (bronze, 30.448).

It was the first medal for Caluag while donning the Philippine colors. He was entered in the BMX competitions in the 2011 Indonesia Southeast Asian Games but was disqualified because of technicalities with his International Cycling Union license.

Caluag competed against a men’s elite finals field that had three Japanese and four Chinese.
Chinese Zhao Ziyang was fourth (31.129) followed by Geng Zhibing (32.284), Wang Baoyu (32.71), Japanese Masahiro Sampei (35.634) and Chinese Li Xiaogang (36.884) in that order.

More than 150 riders from China, Japan, South Korea, the Philippines, Thailand, Indonesia and Kazakhstan competed in the continental tournament, the first Asian championship event of any cycling discipline held in Singapore.

The event served as a showcase for Singapore’s Tampines Bike Park, the world-class track designed by the UCI that was used for the inaugural Youth Olympic Games in 2010.

Hosted by Singapore and organized by Singapore Cycling Federation, the championships served as a platform for cyclists to compete on an international stage and qualify for World BMX Championship."

Perfect the Art of Pedaling

Get Your Pedaling Up To Speed With These Tips

One pedaling drill you can do on any ride with downhills is spinning the pedals as quickly as possible as you accelerate down slopes. To do this correctly, leave the bike in a gear that's too easy,
one that forces you to fan the pedals to keep up with the speed of the bike. Your goal is to rev your legs as quickly as you can while remaining seated. At first, you'll probably bounce a lot on the seat. But, with practice, you should be able to stay in the seat and maintain a calm upper body even though your legs are spinning at supersonic speed. If you do this drill a lot, your pedaling speed and efficiency will quickly improve.

Try Rollers
If you're willing to purchase a handy piece of cycling equipment, a great way to smooth your spin is to train indoors on rollers. Rollers consist of a frame with three spinning drums (one for the front wheel, two for the
rear), with a rubber belt connecting the front drum to one of the rear drums. You put your bike on the rollers and start to pedal and you can balance and ride just like you do spinning down the road outside. Most rollers have optional equipment that allows increasing resistance because there isn't much drag from just the roller unit itself.

Develop A Winning Spin 

Rollers require above-average balance and exaggerate any pedaling flaws. With enough practice, you naturally eliminate pedaling problems because they're so noticeable. And, when that happens, you ride faster with the same effort because your pedaling becomes more efficient and more of
your energy goes into driving the bike.

Think they're just for roadies? Actually, the concentration and spin improvement builds
confidence and the ability to ride tight singletrack, maintain your balance in slick mud and skirt narrow ledges high in the mountains, too.

Forced Spinning 

 A classic cycling trick to improve pedaling technique is riding a fixed-gear bike in the winter. Constant pedaling is required because you can't coast. And you must accelerate pedal speed on downhills because you can't shift. These factors combine to smooth your pedal stroke and force you to spin complete circles. Pick ride routes that avoid steep climbs and descents. You don't need to buy a new bike to pull this
one off, either. A threaded-hub wheel, a track cog, a BMX chain and a few axle spacing tricks can turn your regular bike into a fixed-gear rig. We can help with the conversion.


Try The Track

 If you're one of the privileged few who can ride a track bike at a velodrome (a circular, banked track for cycling), you'll reap the same benefits as training on a fixed-gear bike. Never ride a track bike on the road, though. Brakes are a must on the street, and track bikes don't have them.

Bicycle Chains. How Are They Made?

Check This Out! Making a Bicycle Chain is a Complex Process!

A bicycle chain is essentially a roller chain. It's designed specifically to transfer pedal power to the bicycles rear drive wheel.

The manufacturing process starts with a punch press. It cuts and presses steel into the shape of chains inner link, which looks a lot like a figure eight. Incredibly, the punch press generates 10,000 links per hour! Each of the links have been made to interconnect, their contours formed to travel easily across the bikes gear sprockets.

Samples of these inner links are sent to a measuring station  to confirm the space between the holes is precisely twelve point seven millimeters. The tester also guages the diameter of the holes which must be accurate to within a fraction of a millimeter.

Then the links are baked in an oven at more than 1500 degrees fahrenheit. The blazing heat followed by a quick cool down hardens the steel. They now shovel these interlinks into a donut shaped machine. They add ceramic and silica powders, and poor in a small amount of water.

They then close this lid on the machine. It shakes vigorously causing the powders and water to form an abrasive paste that polishes the links. They load the polished inner links into a metal basket and shut the door.

Machinery plunges the basket into a series of chemical baths to give these inner links a nickel teflon veneer. The nickel teflon surface will resist corrosion, and it's smooth texture will allow the chain to travel easily over gear sprockets.

The bike chain's outer links get a different kind of finish. Unlike the inner links, they don't travel over sprockets so simple nickel plated will do.

They are now ready to assemble the chain one section at a time. Tubes feed the parts one by one into an assembly machine. Gripper arms adjust their position to assemble the links to other chain components such as retainer rings and spacers.

The machinery presses pins into the links holes to secure the assembly. Then grippers move the completed section of chain down the line.

It takes a whole lot of little pieces to build one short section of bicycle chain. The sections are linked together in one long chain, which winds by an inspection station to be examined for flaws.

After that the chain takes a dip in hot oil to lubricate the links preventing squeakiness and wear down the road. The chain exits the lubrication station and travels through an absorbent material which soaks up the excess grease. A laser tool then signals the location where the chain has to be cut and blade chops it at the exact spot.

A standard chain is just over fifty six inches in length. It consists of one hundred fourteen inner links and one hundred fourteen external ones.

And that's more than you will ever need to know about chains!

LEAKED - The 2014 Trek Fuel 29er and Remedy 29er

 Those 2014 bikes are starting to pop up! This time it was all-of-a-sudden!

Trek first released information about this bike a week ago, releasing a brand new 29er model based on the highly successful 26" Fuel EX platform.

Typically Trek and other bike manufacturers make a huge deal out of a bike launch, consisting of marketing campaigns and a huge amount of media attention.

This time, Trek has taken a new approach to their bike launch, keeping it a secret from everyone. Then, last week, trek pulled off our blindfolds and allowed dealers to put their orders in for immediate delivery. Their official 2014 global launch at the end of this month.

Trek has shown three versions of the 29er EX — the alloy-framed EX8, EX9 and carbon EX9.8.

The alloy EX9 receives a RockShox Reverb Dropper post, Deore XT shifting and braking and a Fox Kashima fork. Sounds great, right?

Now check out the specs of the EX9.8:

• 120mm Travel Front & Rear
• Fox DRCV Float CTD Rear Shock
• Fox Float CTD Fork
• ABP Rear Suspension Design w/ Full Floater Shock Mount
• One-piece Magnesium EVO Link
• BB95 PressFit Bottom Bracket
• ISCG Tabs
• Upper Direct Mount Front Derailleur
• 142x12mm Rear Thru-Axle
• Tapered E2 Headset w/ Net Molded Head Tube
• Internal Cable Routing for Derailleurs & Stealth Reverb Dropper Post
• Integrated Carbon Armour and Custom Chain-Slap Protector

And the EX 9.8 gets a well-rounded spec with a full Shimano Deore XT groupset and a Rockshox Reverb Stealth Dropper Post. 720mm low-rise Bontrager RXL handlebars tie all the controls together along with lock-on grips and a stubby Bontrager stem. Stay on the lookout for more posts about 2014 Trek Bikes as well as other product reviews and much much more!!

*Video* 2013 Trek Shift 2 - Has it been awhile? Get back on that saddle with this bike.

So maybe it's been a few years since you've ridden.

Trek has you in mind with this bike's design. It's easy to get back into the saddle. Literally! The low profile of the frame actually makes it easier to get on the bike.

Imagine the shape and compliance of a mountain bike frame and suspension fork, combined with a wider, more comfortable seat that sits on a suspension seat post for extra bump dampening.

Even shifting through the 21 speeds of this bike is made easy with the help of the GripShift shifters. All you need to do is twist the shifter from 1 (the easiest)  to 7 (most difficult) to find the best gear for you.

We're ready to put you on one so you can take a test ride, we know you will love this bike! Bumstead's is located on 1038 W. 4th St. in Ontario. You can reach us at 909-984-9067 or check out our website:

Bike to Work Week and Americans Cycling To Work Increased by 47% Since 2000!

National Bike Month (May 2013) is almost Over! Make sure you participate in Bike to Work Day, Tomorrow, May 17th. 

Bike to School day has already passed on May 8th, but that doesn't mean you shouldn't encourage your children and school age nieces, nephews, brothers, sisters, and friends to participate in this healthy and fun event!! Who knows? Maybe once the week is over they will desire to keep riding their bike to school!

According to the US Census Bureau's American Community Survey, the share of Americans Commuting by bike has grown by 47% since 2000! AND - Many Bicycle Friendly Communities have more than DOUBLED their bike commuter share since 2000!

Also since 2000, the 39 Bicycle Friendly Communities, (taken from America's 70 largest cities and deemed such by the League's Bicycle Friendly America program) saw an average of an 80% increase in bicycle commuting. In contrast, the bike commuter rate in the 31 largest non-Bicycle Friendly communities grew only 32% (which is still great!)

In celebration of these facts and to kick off National Bike to Work Week, the League announced it's latest round of Bicycle Friendly Communities. They have added 17 new BFCs, which brings the 47-state program up to 259 Bicycle Friendly Communities. This program has been helping transform the community's priorities and evaluation of life quality by promoting cycling, hosting education programs in regards to cycling, and investing in infrastructure and municipal policies.

How can you help make your community more Bicycle Friendly? The League of American Bicyclists has provided these steps to get your community more involved in the BFC program:

1. Download the Bicycle Friendly Community Overview Here.

As you review the materials, you'll see that all types and sizes of communities can be positively affected by increased bicycle accommodations. Whether decisions that affect your bicycle plan, routes, and facilities occur in a township, town, borough, city, or county level. this application can help framework a discussion with your decision makers. Also take a look at The League Of American Bicyclists Bicycle Friendly America brochure. You can order free copies of the print version by sending an email to

2. Evaluate your community with the League's Bicycle Friendly Community Scorecard

Take a few minutes to complete this quick scorecard to see how your community stacks up in bicycle friendliness. The scorecard allows you to take an objective look at your community to determine if it already has the basic foundation for a Bicycle Friendly Community.

3. Review the application yourself to see how bicycle-friendly your community is today.

Is there a written policy on maintaining bicycle safe streets? Is there a bicycle advisory committee and/or a bicycle coordinator? These basic resources can be vital to a town's ability to respond to bicyclist's needs. Highway engineers often will not change their practices unless written policy tells them to do so. A bicycle advisory committee is a good structure for getting such new policies written and formally proposed. Having someone on staff designated as bicycle coordinator can be crucial in achieving these measures. (Remember, it is a cardinal rule in every bureaucracy that any task not specified as someone's job is a task that will never get done. Click here to view the application. Pleas note that only applications submitted on-line will be accepted.

4. Plan your strategy for pitching bicycle-friendly improvements.

Obviously, if the mayor is a ride leader in the local bicycle club, your strategy is simple - show him or her the application! Most communities will take a little more work. First, you must identify the decision makers responsible for the policy changes you seek. In big cities, the mayor's office would typically delegate responsibility to the city's head of transportation or public works. In a smaller town, there may be a full-time city manager that reports to a citizen city council. In any event, you must make some calls to determine who needs to be persuaded before you can set out to persuade them. Next, find one or two bicyclists who have some influence with the decision maker. If you're lucky, there is a local government official who is an avid cyclist. Without such a person, identify the most visible bicycle dealer in town and the leader of a local bicycle club. Ask around and find support. If you are a bicyclist who is already known and trusted by government leaders, your work will be much easier.

5. Gather support.

Ask for a letter recommending the Bicycle Friendly Community program from any organization that might be inclined to support better cycling. The local bicycle club is a natural first choice, but local environmental groups, civic organizations, businesses and others will tend to cooperate if you make it easy enough for them. Draft the letter for them so they know exactly what you need to minimize the amount of work you ask of them. The Bicycle Friendly Community program frames positive change for bicyclists into the form of a "yes or no" question to a political leader: "Will you support this program?" Politicians hate to say "No" to anyone. They especially do not want to say "No" to an organized group of people. And it's not likely they will want to say no to many different groups.

6. Call your government official and request a meeting.

Attend with your best spokesperson and copies of the letters of support with you to the meeting. Talk about the benefits that the bicycle improvements you desire, as well as the benefits of a Bicycle Friendly Community designation.

7. Ask for something specific and try to get a specific commitment. 

A good starting point is to ask if the person will submit the application for Bicycle Friendly Community status. Another good ask is how long it will take to designate a bicycle coordinator. One way the city can show its support for building a Bicycle Friendly Community is by adopting the Action Plan for Bicycle Friendly Communities available here. You could also propose working with the new coordinator on implementing the other bicycle-friendly criteria items (such as convening the bicycle advisory committee, proclaiming Bike to Work Day, developing bicycle safe engineering policies, etc.) Be specific in your requests and, if the official raises concerns, ask him or her to be specific. Following the meeting, write a thank you memo that spells out your understanding of what was agreed to.

8. Follow up and Follow up (and follow up).

Lack of persistence is the downfall of many a bicycle advocate. Motivated people motivate politicians and their employees. If you raise an idea and then don't pursue it, they grow suspicious about just how important the idea is to you. So many people are clamoring for their time and attention, they will forget if you make yourself forgettable. Keep calling back and keep going back. Commit to the result and make it happen!

20 Top World Cities for Cycling

Amsterdam has a long tradition of cycling for basic transportation

No US City Gets a Nod in This Eurocentric List

Polling is a difficult art.  You can generally get about any answer you set out to get by how you design the poll.  So, a new poll produced by Copenhagenize Design Co. adds useful information to the question of cycling friendly places throughout the world, but there is at least a chance that their criteria may have been at least somewhat responsible for 3 of the top 20 being in Holland.  Moreover, almost all of the 20 were in Europe, with the lone North American entry being Montreal.

The study took a look at 150 cities in all, and at least my research online did not come up with any rankings or scores beyond the top 20.  It may be that well known cycling Meccas in the US such as Portland and Davis may have come in 21 and 22.  Possibly the folks at Copenhagenize Design Co. will provide more data later.

Their criteria for selection included:

  • advocacy 
  • bicycle culture
  • cycling facilities
  • infrastructure
  • bike share program
  • gender split
  • modal share
  • modal
    share increase since 2006
  • perception of safety
  • politics
  • social
  • urban planning
  • traffic calming
Business insider did a nice analysis of the list with some great picture of some of the cities.  And then did another piece on why Americans don't get it.  Why we don't have a single city that made the list.  
The article quotes Mikael Colville-Andersen, CEO of Copenhagenize, the consulting and communications company that published the Index.
Even if more Americans wanted to cycle to work, the infrastructure
isn't there for them. In the U.S., planners and engineers are
"incredibly stuck in the last century paradigm of 'cars are the only
transport form that we plan for,'" Colville-Andersen said. "We've forgotten that the bicycle used to be a form of transportation."
Many U.S. cities are working to improve cycling infrastructure, but
don't always do so intelligently. Bike lanes are often placed to the
left of parked cars, putting cyclists between moving traffic and doors
that can open at any time.
"This doesn't keep cyclists safe," Colville-Andersen said, calling the setup a "brain fart."
Colville-Anderson also believes that we in the US see cycling as being all about sport or leisure.  And suggests that we are selling the idea of improving the infrastructure based on global warming and fitness rather than on the practical advantages of cycling in convenience and cost.  Cost for both the individual and the various governments, city, county, state, and federal, is many times higher for each car/mile than bicycle/mile.

Southern California is certainly the most ideal place in the world for cycling when it comes to year round weather.  Unfortunately, the region has been set up around cars and a willingness to drive 30 minutes to work and play.  Fixing that might take a generation.  Fortunately, there are forces at work that are pushing in the direction of bicycle friendliness.

2013 Trek Rumblefish 29er Pro Available NOW at Bumstead's!

The Trek 2013 Rumblefish 29er Pro offers 120mm DRCV travel, great small-bump compliance, awesome big hit control.

Let's cut to the chase. The 2013 Rumblefish 29er Pro has 120mm front and rear DRCV travel. With DRCV you can have it all. Most full suspension air-shock bikes use small-volume canisters for pedaling efficiency, but they don't have the best big-hit control. Our solution is a Dual Rate Control Valve that has two chambers which has the best blend of efficiency and simplicity. The front fork also has Trek's DRCV technology to give you exactly the suspension you need for every inch of your ride. That means great small-bump compliance, smooth mid-stroke travel, and awesome big-hit control.
Some maintain that having 29" wheels makes the handling sleepy, but Trek used G2 Geometry to solve that issue. They have included a custom-offset fork and used advanced frame geometry so you have precise handling at low speed, and excellent stability when at higher speeds. The 29" wheels also hold momentum better, so you can keep rolling over the rough stuff and maintain speed through corners.

Come see the 2013 Trek Rumblefish 29er Pro at Bumstead's Bicycles. We're ready to put you on one so you can take a test ride, we know you will love this bike! Bumstead's is located on 1038 W. 4th St. in Ontario. You can reach us at 909-984-9067 or check out our website:

(VIDEO) BikeRadar calls 2013 Trek Domane 2.0 "Best Bike Under £1000 (approx. US$1500)

The 2013 Trek Domane 2.0 offers the ultimate in high-speed cruising comfort.

Trek domane 2.0:
  • Weight: 9.57kg
  • Frame: Aluminium
  • Fork: Carbon, alloy steerer
  • Groupset: Shimano Tiagra
  • Wheels: Bontrager alloy
Throughout the Domane range Trek have introudced their ‘IsoSpeed decoupler’ pivots - Instead of a fixed connection between top tube, seatstays and seat tube this new design allows the seat tube to bow back and forth in response to road or rider loads. A slimmed down pivot section at the top of the tube also means you get a more flexible skinny seatpost, while the Affinity saddle is generously padded too. The result is that the Domane 2.0 offers the ultimate in high-speed cruising comfort.
That's not all though, expect sweet handling, surefootedness and a chassis that is responsive under power.

*NEW* 2014 Shimano Ultegra 6800 Groupset. "For Real World Riders"

2014 Shimano Ultegra 6800 Groupset is 100% Improved

photos courtesy: Shimano
For 2014, Shimano has released their Ultegra 6800 11-Speed Groupset. Dave Atkinson of interviewed Shimano's Mark Greshon. He has this to say about the new group: "Ultegra normally takes the latest technology from Dura-Ace and provides it at a much more competitive price. It's for real world riders who want good performance."

The 11-speed phenomenon with Shimano's engineering power to create this new system that "uses technology that's been proven in WorldTour races, proven at the highest level."
Riders can individually choose from a large variety of gearing options for all kinds of riding. You have the choice between a 11-23 and an 11-32 cassete, and chainring combos include 53-39, 52-36, 50-34, and cyclocross specific 46-36. The 6800 crank shares the same 4 arm design as the Dura-Ace in this category.
The brakes feature the same two axle symmetric pivot design as Dura-Ace as well, an improvement that Shimano claims increases power by about 16 percent. They are available in both a traditional and a direct mount version.

Using a shorter lever stroke which Shimano claims requires 35% less force input, gives tactile feedback to the rider that the shift has been completed. A defined *click* sound will ensure you that the gear has shifted. Improvements on ergonomics and control come from the more compact hoods and bracket grip, as well as a redesigned carbon lever.
The new wheel on the 11-speed level is the WH-6800. The wheel is lightweight on an offset rim for high rigidity and power transmission. Compatible in tubular, tube, and tubless setups. As with all Shimano wheels, the WH-6800 is 100% in-house produced and hand assembled.
The chain has also been redesigned for 11-speeds, and is coated with new surface technology called Sil-tec: an advanced surface painting technology adds a low friction surface treatment that runs smoother and lasts longer.

All in all the new groupset is 35g lighter, and 100% improved.

Tubeless Ready Bontrager Wheelsets include Race, Race Lite, and Race X Lite

Tubeless tires can offer many advantages when cycling: better flat prevention and lower tire pressure which leads to better traction and a smoother ride.

(image courtesy of
Bontrager offers tubeless ready wheels in their Race, Race Lite, and Race X Lite trims, as well as R2 and R3 level Tubeless Ready road tires in 23 and 25mm that are all up to Bontrager's standards for quality and performance.

All the wheels can be run with standard tube tires, or tubeless with the TLR system. THey are virtually maintenance free, and because of the design of the TLR rim strips, there is a low weight penalty for tubes and tires at stock specifications.

There are two ways to go tubeless with the new wheels and tires. If you bought a Trek bike that was equipped with compatible Race, Race Lite, or Race X Lite wheels, Bontrager has a convenient TLR upgrade kit that includes everything you need to make the switch: tires, rim strips, valve stems, sealant, even a valve core removal tool. 

If you're buying the wheels as an aftermarket upgrade, replacement wheelsets include the rim strips, valve stems, and internal cam skewers, meaning all you have to add are the tires and the sealant. And Bontrager has all new TLR sealant. It's formula is free of ammonia, a wide effective temperature range, and ability to seal up to 1/4" punctures. Made in the USA, and comparatively to some other sealants, requires less per tire to be effective. Bontrager recommends as little as .8 oz for 700c, 1.6oz for 27 and 1.7 for 29ers. 

The Bontrager designed hubs on the RXL feature DT Swiss 240 star ratchet internals, with straight pull nail head spokes. 18 DT 14/17g bladed spokes hold the front wheel together, while 24 spokes grace the wheel with stacked drive side lacing for increased stiffness and power transfer. All the spokes are anchored to the 23mm wide rims with Alpina locking alloy nipples. 

Bontrager says the Race X Lite is a performance road wheelset for the rider seeking the best in materials, class leading technologies and unparalleled wheel stability. They provide fast acceleratoin and durability for training.

Greg Kopecky of says: "In a few words - it's all about the rim, baby"

He goes on to say, "these rims have a very unique internal shape and accompanying rim strip - and this is where the TLR part comes in. If you want to run standard tires with inner tubes, you are more than welcome to. Just use a standard rim tape, such as Velox cloth. Put on your favorite tires and tubes, and ride to your heart's content.

If you want to run tubeless, you use the Bontrager TLR plastic rim strip. This covers up all of the spoke holes completely and effectively converts the internal shape of the rim to Road Tubeless."

Once you're out on the road, the Race X Lite TLRs deliver great performance with the flat prevention and ride quality benefits of tubless coming as no-cost bonuses. 

For now, this technology is reserved for only their aluminum wheels. Bontrager's has hinted at the possibility of bringing it to other wheels, such as their 50mm deep Aura 5, or even the Aeolus D3 carbon clinchers.
