Earlier this year Olympic Gold Medalist Jaroslav Kulhavy suffered a devastating knee injury during training, which caused him to miss the first two races of the World Cup series.

While he’s suffered a string of bad luck in his current pursuit of the rainbow stripes this season, he did capture the Czech National title and is now the reigning UCI Marathon World Champion.

Head past the break for a closer look at his custom painted Specialized S-Works Epic. READ MORE ->

EB14: Chris King Lefty Front Hubs Get Official, Plus New Threadfit Bottom Brackets

Chris King Lefty Front Hub in sour apple green

The rumors are true, the Chris King Lefty Hubs are now in production, and there are two versions available. He’s also got a new Threadfit bottom bracket for standard BSA frames that simplify the SKUs for shops offering more crank fit options.

The Chris King Lefty SuperMax hub is a standalone unit, made for Cannondale’s longer travel single-armed forks. The Lefty LD hub uses their standard LD (Large Diameter) mountain bike hub but replaces the axle and end cap then adds a 1mm disc rotor spacer. Rather than run new bearings, they opted to use their current bearings and create a new axle that allows you to adjust the preload like normal. It also lets you run the hub on any of the Lefty forks, from the older models to the race-ready XLR to the monstrous SuperMax.

Details and actual weights below…

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…

2015 Giant Trance_Range_0

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 ->

Whistler Wednesday: Claire Buchar Summer of Summit, Remy Métailler Burns Whistler Bike Park, & A Whole Lot of Stoke

As a woman, I take an active interest in the various edits starring female riders that stream through my inbox. Almost always though, they’re disappointingly cutesy. Relying more on smiles for a sponsorship than a banger, so viewers are left with the bad taste of poorly used slomo instead of stoke.

Women like Casey BrownManon Carpenter, and Micayla Gatto, have been holding it down, but Claire Buchar just raised the bar. Hulk smashing through roots, an epic no hander, with a touch of classic Kovaric, make this one of my favorite edits of the year.

But wait wait, there’s more. READ MORE ->

EB14: Jagwire Warms up to Disc Brakes w/ New Finned Cooling Rotors

jagwire elite cr1 finned brake rotor

Jagwire is jumping straight into the premium category with their new Elite CR1 vented 3-piece brake rotor.

The three piece design pairs a stainless steel braking surface with stamped aluminum fins pinned to them. Those sit on a forged alloy spider, which helps keep the whole thing very stiff.

They’ve benchmarked them against Shimano’s IceTech rotors, and they say performance is equivalent, even being a hair better, for the first 100 seconds they’re the same. And how often are you braking for 100 seconds? Performance, in their tests, refers to heat management. Theirs stayed a bit cooler during the first minute of braking…

Giro & Bell Partner With MIPS & IceDot, Plus Bell Launches New Multi Impact Rated DJ Helmets

 

Giro MIPS Diagram

If you’re unfamiliar with the technology, MIPS is the biggest buzzword in helmet safety today. The acronym stands for Multi-directional Impact Protection System, and is a technology that seeks to reduce the damage from angled impacts. It works by using a liner inside the helmet as a low friction slip plane, which allow the helmet to rotate slightly in a crash and helps absorb rotational energy.

Both Giro and Bell will be launching helmets with the technology that span their commuter, road, and mountain bike line ups.

At trade shows everyone seems to ask the same question – have you seen anything cool? Most of the time there are a lot of interesting products, but especially in a show the size of Eurobike it’s hard to really stand out. Schwalbe seems to have no such trouble thanks to their game changing tire technology – Procore.

After a few good teases, the production version of the system was unveiled tonight at the Dornier Museum Friedrichshafen which happens to be a fitting shrine to German engineering. Since we last reported on the technology a few things have changed including the amount of compatible rims. Full details next…
