2014 Trek 820 - Beginner MTB Heaven

(Review) 2014 Trek 820 is Versatile Enough To Start You Down Those Mountain Trails

You've been eyeing those foothills for a while now, but that road bike in the garage isn't going to take
 you down the paths you want to ride down. You need something with a little more "oomph" — the 2014 Trek 820.

Check out our recent post and video on the 2014 Trek 3500 Disc!

For the ride to work, or the road on the way to the mountains, you won't need to worry about the potholed city streets or how your bike is going to react when you jump off the curb. For the trail, small rocks and divots in the road will be easily handled by the Bontrager LT3 26x2.0" tires, aided by the 75mm of front suspension provided by SR Suntour coil spring fork.

It's forged alloy, 3 piece crank and Shimano TZ-31 7-speed cassette allow for plenty of different gear options to choose from, and the Shimano Tourney shifters and derailleurs will assure a quick and seamless shift through those gears.

Bontrager handles all the comfort components on this bike, from the Riser 25.4mm Handlebar to the SSR seatpost, and Tektro alloy linear pull brakes are fitted for capable stopping power.

So quit eyeing the foothills, come by the shop today and test ride a 2014 Trek 820. You'll be glad you did!

[VIDEO] 2014 Trek 3500 Disc is Versatile and Ready For You!


The 2014 Trek 3500 Disc is  Perfect For the Light Trail/Commuter/Urban Rider

When it comes to functionality, Trek knows both what you want and what you need. What you need is a bike that will take you back and forth from work, allow you to carry some groceries home from the market, and to help you stay in shape.

What you want is a mean-looking, trail-ready, durable machine with quality components and a nice paint job. Right?

That's exactly what you'll find in the 2014 Trek 3500 Disc. The frame is made of Trek's Alpha Silver aluminum, which is lightweight and features smooth-welds at the joints.

The front fork is an SR Suntour M-3030 w/ coil spring, and 75mm of travel. This little bit of suspension will help take you over some otherwise undesirable patches of road and trail without killing your hands.

The all-Shimano drivetrain is a plus, allowing you to easily use the Altus EZ-Fire 51 7-Speed shifters to send the chain through the Shimano Tourney Front and Rear (TX35) Derailleurs, on a Shimano M131 48/38/28 Crank and over the SRAM PG-730 12-32 cassette. If for some awful reason you have to slow down on your ride, you can do so using the HL 280 mechanical disc brakes (Shimano Altus levers).

The 3500 Disc is outfitted with Bontrager's standard (which is a pretty high standard!) Saddle, Handlebar, and grips — from it's SSR family of products.

We can only talk about this bike so much — we'd love to let you take one on a test ride! Come by the store and see if this is the bike for you. If not, we've got a large selection of Trek bikes for you to choose from. We look forward to seeing you soon!

2014 SRAM X01 1x11 Mountain Drivetrain - RELENTLESS

The SRAM X01 drivetrain carries on the tradition of SRAM’s championship-winning 1X™ philosophy—all the way down the mountain. 

The setup is simpler. The drivetrain is lighter. And the shifting is fast and solid. Bottom line: X01 is the right one for any terrain, every time. RELENTLESS.

X-Horizon Rear Derailleur, 220g

"The XX1 rear derailleur looks different from other gear changers, owing to its “straight parallelogram” design. Unlike most current derailleurs, which use a slanted parallelogram to follow an angled path and maintain a constant gap between upper pulley and cogs, this one moves only in a horizontal plane.

To maintain the proper chain gap, XX1's upper pulley is radically offset from the center of the pulley-cage pivot. As the rider shifts, the pulley cage rotates to take up the chain slack, causing the upper pulley to move vertically, keeping it close to the cogs. SRAM claims this design, 'is faster, reduces shift force, and eliminates ghost shifting.' "

XX1's uses SRAM's new SRAM's Type 2 design, a one-way roller bearing clutch that limits chain bounce for better drivetrain stability and a quieter ride. The Cage Lock also holds the pulley cage forward for easier wheel removal.

Cassette 260g

The XX1 cassette is eleven speeds, with a 10-42 range. SRAM developed a new, patent-pending body they call XD to deal with the sizing issue between the 10 tooth cog and a standard hub's driver body. Chris Hilton (SRAM's external drivetrain product manager) said SRAM shortened a typical driver body, and moved the threads from inside to the outside, and further inboard.

Instead of an outboard lock ring that tightens the cassette onto the driver body, the XD cassette has a threaded seeve inside the cassette that pulls it into place. Hilton says this design allows SRAM to buld the cassette as one piece with no loose cogs or lock rings. This means you won't need ANY tools to remove the cassette!

Cranks 650g (BB30)

While there's nothing new with XX1's crank arms the X0 carbon arms with a forged-aluminum spider is optimized for use with a single ring. Offered with either BB30 or GXP axles, and in both 156mm and 164mm Q-Factor. XX1 bottom brackets use ceramic bearings.

It's easy to swap rings, thanks to threads on the chainrings themselves, which means you don't have to worry about losing any nuts, should you choose to swap rings mid-ride. But, because the derailleur's performance is dependent on having the right length chain, adding or removing a few links may be necessary if you change to a ring that has more than a four tooth difference from what you're currently running. But, Hilton says that in most cases, moving up or down one ring size should not require altering chain length.


Because XX1 is designed around a single ring, and doesn't need to shift, the chain can be more robust. The 11-speed specific chain is slightly narrower than SRAM's 10-speed chain, and requires an 11-speed power lock. SRAM says the chain features a proprietary finish on the inner links, which consists of a coating and polish that gives it a slick, hard finish to reduce wear between the plates. The chain has hollow pins and windowed links, and weighs about the same as a SRAM 1090r 10-speed chain.

Shift Trigger; GripShift

Other than the extra click, XX1 shifters are basically identical to X0 2x10 triggers. There is, however, a carbon pull lever, and carbon cover. Or, you can opt for a GripShift changer, also nearly identical to it's X0 cousin. The shifters come with Gore Ride-On cables.

Mens Fitness Magazine Names 2014 Trek Domane 6.9 in Top Ten Best Road Bikes

2014 Trek Domane 6.9 is Named in Top Ten Road Bikes for Serious Cyclists

Here's what the magazine had to say about the bike:

"Road bikes designed with race geometry are great for competition, but they’re typically uncomfortable on longer rides. No need to suffer, or to lose your edge—Trek’s Domane 6.9 sports an IsoSpeed decoupler that isolates the seat tube from the rest of the frameset for a more comfortable riding position that doesn’t compromise power transfer to the road. And it’s smooth and stable enough to power comfortably over centuries-old European cobbles, or your nearest potholed country road. "

The 2014 Trek Domane is claimed by Trek to be the World's best endurance bike.

Here are just a few of the reasons that the 2014 Domane 6.9 takes the cake.

Isospeed DeCoupler: The IsoSpeed decoupler isolates the seat tube from the rest of the frameset, doubling compliance and smoothness with zero performance drawbacks
600 Series OCLV: Over two decades ago, Trek engineers developed Optimum Compaction, Low Void carbon manufacturing process, enabling them to produce carbon bikes with consistency and quality previously thought impossible. To this day, Trek OCLV carbon frames are the best, most consistent you can buy.

Endurance Fit: As befits Domane, the world's most advanced endurance racing bike, we've developed the world's most comfortable racing geometry. Still racy, but with a slightly higher head tube. You're more balanced over the bike for stability, and your back stays more comfortable through the entire ride.


IsoSpeed Fork: It's a one-two punch: generous ride-tuned sweep and shape increases compliance for a smoother ride, and unique dropout placement optimized the wheelbase.

Power Transfer Construction: Get more out of every pedal stroke with Power Transfer Construction. This Trek innovation applies more of your pedaling power to the road by optimizing the head tube/down tube/bottom bracket/rear wheel connection.


StepJoint Technology: After molding each specific piece for a frame, Trek joins the "lugs" into a complete frame using StepJoint Technology, or proprietary method of bonding two carbon structures together perfectly, with no overlap, no excess carbon, and consistent tube wall thickness throughout.

Performance Cable Routing:  Trek's performance cable routing is highly engineered for unshakable precision and the real-world performance that comes from better compatibility with current drivetrains. Optimal routing through the frame provides flawless shifting, better braking, sleeker aerodynamics, and easier assembly and maintenance.

BB90: BB90 is the widest bottom bracket available on a road bike. This Trek-exclusive carbon BB makes the frame lighter, stiffer, and quicker to accelerate. BB90 also eliminates the need for extra inserts and parts in the bottom bracket/frame junction. Fewer parts mean a lighter frame — and a lighter frame means a faster ride. 

Bontrager RXL IsoZone bar: Turns cobbles into concrete. Vibration from rough roads can cause numbness, fatigue, even loss of control. Trek's exclusive solution: integrated IsoZone handlebar pads that reduce vibration displacement by 20% while keeping the same ergonomic profile. You get comfort and confident control, with less additional weight than add on solutions like gel padding or double wrapped tape.

2014 Bontrager Update Part 2: Serano Saddle, ION 700 USB Light, Travel Charger Pump, and Updated Clothing Line

You've seen the 2014 Bontrager Velocis Helmet and Team Sky Shoes (Oh — You Haven't? Click The Link) Now Check Out Some More Bontrager Updates for 2014!

New Serano saddle

Another 2014 product which debuted at the Tour de France but which has now officially broken cover is the new Serano saddle.

Bontrager says the shape of the saddle is based on the Fizik Arione, a popular choice in the peloton, but uses two of the key technologies found on other Bontrager saddles: Zone Density Foam and an inForm BioDynamic design, giving the saddle a high tail to provide a power-friendly profile for riders who adopt an aggressive position.

There are two versions of the saddle: the carbon-railed RXL, which has a claimed weight of 185g, and the RL, which has titanium rails and a marginally heavier claimed weight (TBC).


Updated clothing line
Bontrager’s clothing line has been updated with new colors across the range. They’re also now using their own proprietary fabric called Profila. They say it does everything you’d expect a premium fabric to do – it’s lightweight, breathable and fast-wicking – but by using their own fabric Bontrager say they’re able to tweak its properties according to the type of garment.

So, for the 2014 spring/summer range, there’s Profila Cool, for maximum breathability, Profila UV, for block out UV rays, Profila Power, a compressive fabric designed to offer support and Profila Dry, designed to wick moisture rapidly and dry quickly.

The RXXXL jersey, for example, uses Profila Dry, while the corresponding bib shorts are made from Profila Power. The RXL Summer jersey, meanwhile, is designed for the hottest of days and is therefore made from Profila Cool with Profila Dry inserts.


New ‘see by’ light

The Ion 700 USB is Bontrager’s first ‘see by’ light. As the name suggests, it has a claimed output of 700 Lumens, which is venturing into serious light territory and should be plenty in principle for serious commuting and some training on unlit roads.

The light, which is USB rechargeable, has five modes (three solid and two flashing) and can be rotated 360 degrees on the quick-release mount. It’s a compact unit, which also has side illumination by way or two small, yellow windows.

Finally, this Travel Charger pump is also new from Bontrager. It’s a travel version of the existing Charger track pump, designed as a high-volume pump for when space is at a premium, so to chuck in the back of your car ahead of a sportive, or in a bike bag if taking your bike abroad.

It folds down into a neat package which is far less obtrusive than a traditional track pump and has a folding foot platform to help get your tires pumped up in double-quick time.

2014 Bontrager Helmet Technology and Team Sky Shoes

The 2014 Bontrager range includes a new top-of-the-range helmet, an updated shoe line, a new saddle modeled on the Fizik Arione and Bontrager’s first ‘see by’ light.

The Velocis is Bontrager’s new top-of-the-range helmet – the eagle-eyed among you may have spotted it on the heads of some Radioshack-Leopard riders at the Tour de France.

The Velocis supersedes the Oracle (which itself remains in the range) as Bontrager’s flagship road lid and they say it’s  their “fastest, lightest and most innovative helmet ever”.

The key change is the use of a composite inner skeleton which Bontrager say allows them to use larger vents without compromising the structural integrity of the helmet. It also helps keep the helmet’s weight down at a claimed 228g.

The Velocis uses Bontrager’s existing Headmaster II fit system, which uses an adjustment dial at the rear of the helmet, and a cradle which can be set to three different height, in order to fine-tune the fit.

 Inside the helmet, the FormFit brow band is designed to form to the shape of the forehead. It also runs the length of the entire brow to help stop sweat running down to your eyes. One particularly interesting feature is the optional NeoVisor; a removable visor which slots in front of the brow band and attaches with a handful of small velcro patches. As a result, it’s said to have no impact on fit and will keep the sun or rain out of your eyes, much like a traditional cotton cap.

The Velocis is available in four colors, including the matte black/charcoal option photographed at Trek World.

One of Bontrager’s key strategic goals is to be recognized as a standalone brand, rather than purely as a subsidiary Trek. One of the ways they want to achieve that is through the sponsorship of professional riders who may not necessarily be associated with either Trek (as they ride for a team with a different bike sponsor).

One of those riders is Kanstantsin Siutsou, who uses the Bontrager RXL shoe in this limited edition Team Sky colorway. Now it’s available to the public, too, but only in limited sizes (41-45) and limited numbers.

The RXL is, of course, available in a range of regular colors. The sole has a rating of 12 (the highest possible) on Bontrager’s stiffness index and claimed weight is 276g per shoe.

Both the RXL and the RL (which is available in the new-for-2014 high-viz yellow pictured above) have a new low-profile buckle, originally designed for Bontrager’s mountain bike shoes in order to prevent the buckle hitting rocks and roots.
