First Look: Trek Session and Session Park, Two Different Ways to Ride Big Mountain – Plus Actual Weights

2015 Trek Sesssion 27.5_0

It’s hard to explain to outsiders the subtle but important difference between the stack of bikes that often clutter a cyclists garage, but even subtle differences in geometry can affect performance. And at the highest level of the sport, those differences are amplified.

For the downhill crowd, that narrow but almost imperceptible divide in bikes is between racing and big mountain or slope style riding. Both categories require a bike that may visually look similar, but they are two separate and distinct riding styles. Working with their stacked team of racers and slopestyle athletes, Trek has introduced two new iterations of their Session DH bike to help meet both groups needs.

First Look: Anvil Components Expands Lineup with Carbon Handlebars and Composite Pedals

Anvil-Components-Catalog

Despite having only launched last year, Anvil Components is already hard at work expanding their current product line. Having nailed down the aesthetics, geo, and tech for several products, they’re now playing with different materials.

Their Mandrel handlebar, which we reviewed earlier this year,  is now available in carbon. At 227 g, it’s ~70 g lighter than it’s aluminum counterpart, while still sharing the great ergonomics and graphics.

EB14: Maxxis Adds New Mountian Bike tires, More Tubeless Options & Some Road Rubber

maxxis pace and tread lite mountain bike tiress

The Pace cross country tire we’ve been seeing on pro bikes doesn’t have distribution in the U.S. or Germany. While we don’t have an explanation for North America, the Germans say it’s too heavy for XC racing, so they don’t bother importing it. Word is, the lowest weight version is around 700g, which is a bit portly for XC.

The solution? The new Tread Lite, a semi slick that’s tipping the scales at just 530g for a 26×2.10. The 27.5×2.10 is 560g or 595g with the EXO protective casing. 29ers are 590g and 630g. All are tubeless ready, which they designate simply as TR, and have 120tpi casings.

Now, on to more aggressive knobbies, which includes the road bike rubber…

EB14: Industry Nine Teams with Reynolds for U.S. Made Pillar Hookless Carbon Wheels

Industry 9 I9 carbon us made reynolds rim hookless boost 148 hub (10)

Not only are the new Industry Nine Pillar carbon wheels the first hookless rim design for the companies involved, but the wheels also represent the first completely US made carbon wheelset for the brand. With the exception of the bearings and o-rings, the Pillar wheels get the made-in-the-US moniker thanks to the new hookless carbon rims that are made possible by their collaboration with Reynolds. As one of the first mountain bike rims that Reynolds is manufacturing in the US, the rims use a design by Industry Nine.

Still largely in the preproduction phase, I9 plans to have four different models available in both 27.5 and 29″ sizes. Matched with Industry Nine’s legendary hubs and aluminum spokes, the wheels are designed to provide excellent stiffness, ride, and durability while staying a light as possible.

EB14: DT Swiss Updates, Narrows Suspension Lineup & Expands Wheel Options for Road & MTB

DT-Swiss-2015-OPM-ODL-suspension-fork

The 2015 DT Swiss suspension gets revamped, bringing their shock tech up to speed with modern features and simplifying the fork offerings to just two models offering five different travel options depending on wheel size. Inside, the damping circuits also get a reboot to improve their range of performance and make them a bit more plush. Turns out those new graphics we spotted on the pro bikes were more than just cosmetic changes!

Meanwhile, the mountain bike wheels get a new premium DH/Freeride wheel and a three-modle Spline Two group that has impressive features for the price. And there’s more new benefits across the range. For road, almost everything’s now tubeless ready, and the alloy wheels are starting to get wider…

EB14: MRP Waves Good Bye to Narrow Wide, Wiggles New 1x Chainrings into Production

MRP New Wave Chainring narrow wide non drop carbon chain guide slope fork (6)

Clearly, 1x drivetrains are so hot right now. At the center of the trend is the concept of the narrow wide chainring which uses alternating tooth profiles that are thick then thin to essentially grab the chain and keep it from bouncing off. Like all drivetrain components, chainrings wear and one of the concerns with the narrow-wide design has been the ability to retain the chain retention properties once the wide teeth start to wear out.

MRP’s answer to the quandary is to get rid of the narrow wide tooth profile all together. So how do you make a chainring that will retain the chain without the narrow-wide teeth? For MRP it’s all about riding the wave.

Full details on the new Wave chainring plus new chain guides, forks, and more, next…

EB14: Yeti SB6c Gets Official, Switch Infinity Stretches Out

Yeti SB6 carbon switch infinity (2)

In the past few months, it was hard for Yeti to keep the new SB6c under wraps. After all, the bike was raced twice in the Enduro World Series by Jared Graves, and both times Jared and the new bike were on the top step of the podium.

“The SB6c was built as a pure enduro machine and proved it’s mettle before it went into production by winning two consecutive rounds of the Enduro World Series.” said Yeti President and co-owner Chris Conroy. “Long-time Team Yeti rider, Jared Graves, was critical in designing this bike. He worked with our engineers to create the ideal leverage curve and was instrumental in nailing the geometry which is long, slack (65.5° head angle) and low.”

After the stealthy prototype made its way around the internet, today Yeti made the SB6c official making it the second bike to use Switch Infinity. As the bigger brother of the SB5c, the Enduro proven SB6c looks ready for prime time…

EB14: Single Speed Kit in a Box with Thomson’s Crate Motor, Thomson Ti Bikes, more

When you think of Thomson you probably envision stems, seat posts and maybe handlebars at this point. But with Thomson’s latest project, you might just be left thinking single speed drivetrain. In addition to the components themselves, the concept for how the single speed parts will be sold would be unique to Thomson. Creatively named the Crate Motor concept, Thomson’s marketing manager David Parrett envisions the entire single speed drive train to be sold in a single box. That would include the forthcoming Thomson crank, bottom bracket, bash guard, true single speed chain ring, chainring bolts, chain, their new single speed cog system with 2 ratios, clear acrylic cassette body spacers, and a lock ring for somewhere around $700.

Of course, the parts would be available separately as well including the new single speed crank. Why would Thomson make a crankset? Part of the idea is to offer a cohesive single speed drivetrain package that also just happens to match the rest of their components. It’s also a chance for Thomson to do some interesting things with the design like coating the crank arms in Keronite instead of anodizing them. The Keronite coating not only wears better than anodizing but doesn’t effect the total part’s shelf like anodizing. Other touches will include a nickel plated spindle, steel helicoil inserts for the pedals, and standard 104 BCD. Some details are still yet to be worked out, but Thomson plans to have the forgings done in Taiwan with the machining done in the US.

The other big part of the Crate Motor is the new single speed cog system. Aluminum. Steel. It has it all…

First Look: 2015 Giant Trance and Reign – Plus Actual Weights

2015 Giant Trance_Range_0

Last year, while the other members of the Big Three had not fully committed to the 27.5″ wheel size, Giant proclaimed that this was the future of the sport, and launched an extensively redesigned lineup that featured dozens of new 27.5″ models.

At Crankworx, we took the opportunity to visit with the company and take a closer look at the Carbon Trance and all new Reign. READ MORE ->
