EARLY RELEASE - 2016 Trek Crockett And Boone Revealed

Only One Quarter of 2015 Has Passed, But Bring on Next Year's Model Bikes from Trek

(originally posted on cxmagazine.com)

Trek Bicycles has recently released a few details on their lineup for 2016 cyclocross bikes: The Boone and Crockett. The bikes still have their trademark IsoSpeed decoupler and frame geometry. Apart from colors and drivetrain package options, the key difference looks to be Trek’s investment into thru axle technology, moving to a 15mm thru axle front hub for 2016, although they will be keeping the rear as a quick release.

All of the race models shown in our slider below, including the framesets, come equipped with a carbon thru-axle fork. The aluminum Crockett 5 Disc and carbon Boone 5 Disc will come with an aluminum steerer. The remaining four disc models: The Crockett 9 Disc, Boone 9 Disc, Crockett Disc frameset and Boone Disc frameset, will feature full carbon thru-axle forks with carbon steerer tubes, shaving a full 120g off the weight.

Already have a Boone or Crockett Disc bike? Trek is also releasing an upgraded solid black full carbon fork you can use on the older bikes to replace quick release forks.

More concerned about color selection? Here’s what Trek has to say on the matter: “Through some highly scientific and complicated research, our engineers found that the new color schemes will give you 16.2% more heckles and a whopping 18.6% more handups during races.

Trust us – we use science and stuff.”

2015 Trek 1.1 VIDEO REVIEW | Bumstead Bicycles

Lloyd from Bumstead's Bicycles brings you the 2015 model of Trek's 1.1 Road bike. Perfect for the rider who is just starting or just returning to the sport.



The hydroformed tubes of the 2015 Trek 1.1 allows for lighter weight yet retains great strength, especially for an aluminum frame.

Another great feature is the carbon fiber front fork. That allows the bike to have a more compliance, lending to the overall comfort of the ride.




The 2015 Trek 1.1 comes with a Shimano Claris Drivetrain, including front and rear derailleur, chain and cassette. Saris is an 8 speed system, so you have a total of 16 gears.




The second half of the drivetrain is the STI (Shimano Total Integration) Shifters and brake levers. These shifters allow you to keep your hands on the handlebars at all times, even when engaging the shifters or the brakes.




To sum it up, this bike is an amazing package of components all put on to a state of the art frame and fork. A great value, excellent performance at a very reasonable price. You can't go wrong if you choose this bike as your first road bike!

Bicycle Brake Pads Making Noise or Vibration? Here's an Idea for Best Positioning


102493-1
 BikeTestReviews.com is a fantastic resource for getting a serious engineering perspective on new products and other mechanical aspects of the cycling experience. Here is what the site had to say about this age-old question.

 Position your road bike’s brake pads where exactly?

2Last Saturday, while waiting for everyone to arrive at the group ride, the self-proclaimed bike repair guy, whose shop is in his basement, was helping a female cyclist who was fairly new to the sport. She told him that something was rubbing and shaking while she was riding, especially when braking. He took the bike for a quick up the block and back and told her it was her brake pads. She was running them dead center on the brake track and he said that he prefers to see them as high as possible. I sat there for a minute trying to understand his logic which still doesn’t make sense.
The True Answer is that it’s better to run the pads lower than higher (lower as in closer to the spoke nipples than higher which is closer to the tire). In fact, its best to run them as low as possible just before they start hitting the side of the rim. There are two reasons for this.
  1. From a manufacturing point of view - when machining the braking surfaces, the lower area is supported by the inside of the rim, the upper area has no support and therefore the upper area of the brake track will deflect slightly when machining and will ultimately have more unevenness than the lower part of the brake track.
  2. From an operational point of view - again, the upper part of the brake track is unsupported and will therefore deflect more, i.e., pulsate more under heavy braking.
In summary, the lowest part of the braking surface will have a more concentric width, less tendency to pulse and less compression.

2015 Trek Domane 6.9 Disc Review, Features and Specs - Bumsteads Bicycles

Dont endure. Conquer. 

The Domane 6.9 Disc may use the original Domane mold but with heavy re-tooling around the drop-outs the take away is something significantly different than what we experienced with the original Domane or the Classics Edition. 

Boasting Shimano’s R785 hydraulic Di2 disc brakes and levers adds incredible stopping power and single finger modulation, but when its combined with additions like front and rear thru axles, fender mounts, and a host of Trek specific proprietary features the Domane Disc easily becomes the most versatile machine in Trek’s line.


The amount of torsional rigidity provided by the thru-axles was surprising and eye-opening at how much flex there really is with a standard quick-release design. Otherwise, the 6.9 felt like a Domane with an excellent ride quality, thanks to the IsoSpeed decoupler that creates a pivot point between the seat tube and top tube joint in order to greatly improve compliance.

Contructed from the proven 600 Series OCLV Carbon frame, with race-optimised cable routing,Trek IsoSpeed decoupler gives you an incredibly smooth ride with exceptionally stable geometry and flawless gear shifting.

Grand Fondos, centuries, long rides on not-so-smooth roads? The Domane is your bike. Crushing the competition over Europe's cobbles? Well, that's Fabian's thing. And now it's yours as well.
