EB14: Roundup – Silverback’s Superbike Concept, Plus Asian Examples, Ti, Carbon & Other Hacks

silverback-sbc-superbike-concept-full-suspension-XC-race-29er

Outside the exhibit halls were the award winners, among them Silverback’s SBC 29er full suspension race bike. Standing for “Superbike Concept”, it takes their technology to the brink to see what they can do. It’s not their only one, but this one caught our eye for the rather unique suspension design.

The closeups of that are after the break, but there’s more to it than that. The frame uses internal mandrels to help shape it and provide a strong enough base to layup longer strands of carbon. The result is a lighter, stronger and stiffer frame. The rear derailleur cable runs under the downtube in full length housing, and there’s room for a front mech’s cable, too, even though this one’s spec’d with a Race Face Next SL single ring crankset. There’s also a removable front derailleur mount, keeping things clean when you’re running a 1x.

Out back, a replaceable threaded insert fits 12×142 thru axles. On the left, a strut connects the seat- and chainstays to not only provide a rigid braking platform but also cool the rear brake. It’s angled, helping direct air over the rotor to blow heat away. Now, about that suspension…

Prototype Ritchey Timberwolf Long Travel Hardtail Mountain Bike Spotted

Prototype Ritchey Timberwolf long travel hardtail mountain bike

Looks like Ritchey’s expanding their steel mountain bike collection with the new Timberwolf. It’s not the first time it’s been spotted, and we’ve pieced together a few details from comments here and there. Word is it’s designed for a 140mm fork, which means it must get a tapered headtube…and from the looks of these pics, it’s a beauty of one, too!

Other early information includes a 67º head angle / 71.5º seat angle, 180mm rear rotor post mounts, 30.9 seat post and  QR/12×142 convertible dropouts. The pic above shows it on the trail with 27.5×2.35 tires, so it’s got clearance and it’s 650B. This pic and the next popped up on their Facebook Page over the past couple days, but then an anonymous tipster spotted it headed out for a ride, giving us a much closer look at the bike…

Putting the Mavic Crossmax XL WTS and Fury Shoes to the test with Jeff Lenosky

photo 1 photo(14) copy

It isn’t every day that a mountain bike super hero calls you up to go for a ride. Naturally, when Jeff Lenosky asked for us to show him around the trails at Brown County State Park in Indiana I jumped at the chance. He would get an opportunity to ride the notoriously difficult trail known as Schooner’s Trace, and I would get a chance to try out the latest treads – for both the bike and my feet.

This wasn’t my first time aboard the Mavic Crossmax XL Wheel Tire System, but it would the first time that I was able to ride them on trails in my backyard. On a perfect late Summer’s day we set out on what turned out to be an awesome ride with Jeff clearing all of Schooner’s. That may not sound like much, until you see the video of one of the more challenging sections next…

Factory Tour: The Garage Shop & Growth of Gamut USA

Gamut Chain Guide

The word Gamut means broad or far reaching, and judging from the Gamut’s presence at all levels of racing, it’s easy to imagine they’re a large corporation. Yet despite the polished website and big name sponsored athletes, Gamut is actually a small, rider-owned company.

Their idea for a better chain guide came about because Co-Founder Juan Graziosi wanted a lighter & more reliable solution for racing. Working in conjunction with his father Ed Graziosi, a machinist, they fabricated a working prototype in their garage. The idea would have likely ended there, but soon friends and fellow racers wanted guides as well, and selling the home made components quickly became a way for Juan to offset the cost of racing. The project began to look like a viable business venture when older brother Mateo and riding buddy Michael Poutre joined to to help crank up production and craft a business plan.

Today, Gamut continues to produce a large quantity of their products in the garage where Juan and his father created their first chain guide. Learn more about the process after the break…

IB14: New Co-Motion Disc Brake Road Bike, Gravel Grinder, 29er & 650B Touring Bikes & More!

2015 Co-Motion Camino disc brake road bike

C0-Motion has a way of making steel look really, really good, and their latest new and updated frames continue to make the classic material modern.

The Camino is their all-new disc brake road bike. They introduced disc brake cyclocross and gravel bikes over the past couple years, and now there’s a proper pavement pounder in the mix, too. Its geometry is a bit more relaxed, like a Gran Fondo bike. It’s paired with a new tapered, full carbon fork with 47mm rake.

The frame is Reynolds 853 with a tapered headtube. They built in fender and rack mounts front and rear along with a frame pump tab. The dropouts are particularly interesting…

Atomik Carbon Rolls In On New Carbon Fiber Wheels and Handlebars

Atomik Carbon Press Kit Tailwhip

Photos from Atomik

Atomik Carbon has been working on their new tubeless wheel line for over two years.  We had a short test on them earlier this year, and had a closer look with them as well during their development.  Now, ready for launch to the public, they are giving us the full specs, details and prices of the product line.

Atomik has created a line of rims that do more than just change width for the differing purposes of XC, Trail and AM.  They all use a thicker sidewall with a proprietary material designed to absorb impacts, and a combination of Toray T700 and T800 fibers.  How the rim is used though, will affect the final design…

Vee Tire Co Offers Manufacturers Easy Customization

Vee Rubber easy OEM customization

You’ll probably be seeing more Vee Tires equipped on bikes in the future. That’s because the company is making a big push into the OEM market with their new guidebook designed to make the customization process as easy as possible. Offering companies the chance to pick their own tread patterns, color options, hot patches, sidewalls, and even special treatments on the shoulders, the move means we’ll not only see more Vee tires, but tires that will probably match the bike.

Obviously this is bigger news if you are a manufacturer, but it does mean the possibility for stock bikes to ship with better tires thanks to low prices and low minimums.

EB14: Rotwild Brings Schley’s Shredder to Life, Make Race Bikes Lighter & Show AMG Team Road Bike

2015-Rotwild-Richey-Schley-RG1-gravity-bike

Spotted in prototype form this summer at the bike park, Richie Schley’s new 200mm gravity bike is not so much for downhill as it is for him to crush trails in Whistler.

They finished up testing this summer and, thanks to a killer response from riders after seeing it in prototype form and Schley himself, made the commitment to go into production. It’s designed with a low BB, low standover and a short rear end (440mm chain stays) so he could whip it in the air. Goal was to give it the bigger roll over capabilities of 27.5″ but keep it as nimble as a 26″ bike.

More details on this, plus the revised team 29er FS and hardtail bikes, the road bikes they train on and *gasp* e-bikes, below…
