Apparently Cam Zink was so excited to show off his new Birzman Tiny Tanker and Maha Apogee III that he forgot his prototype YT Industries Slopestyle bike as in the background. Ok, not really – he even mentions it on his Instagram feed. Rumored to be soon coming to the U.S., the carbon prototype looks to have a BB concentric pivot due to the ability to run singlespeed.

In order to remove nearly every rear bicycle wheel, you have to separate the chain from the cassette. In certain instances, that can be prove to be tricky – not to mention the potential for grease to get on your hands, gloves, car trunk, etc. Jan Deckx thinks there is a better way.
As the inventor of D-Fix, Jan came up with a way to attach the hub and the cassette in a way that leaves the cassette in place when you remove the wheel. Sort of a thru-axle housed in a quick release hub, the cassette uses a spring loaded engagement system that retracts when the axle is removed. Jan tells us that he currently has 10,000 km on this hub pointing towards its durability.
Watch a video demonstration of the hub system next…
Last year, Yeti made the difficult decision to abandon the World Cup Downhill scene in order to support their Factory Enduro World Series Team, which included top contender Jared Graves, and up and comer Richie Rude.
Mid way through this years EWS Campaign, they released two well received trail & enduro models sporting their new Switch Infinity Platform, and shortly thereafter, Richie Rude was spotted testing a long travel aluminum prototype. Details regarding that prototype have been scarce, although on a post on MTBR, the Colorado based company claimed the test mule was simply being used to dial in kinematics and geometry, and that a new model was no where near production.
Despite these claims, Jared Graves just posted this incredible new build to his Facebook page.
Joseph Magee, the product developer of the VECTr, is looking for feedback on his design as he conducts market research. The name is short for the Variably Expanding Chain Transmission, and is a new way to change your front drive ratio. They have built a working prototype along their journey towards production.
The system is said to be better than typical current designs by reducing the wear and friction of a front derailleur, reducing wear on the chain from drastic chain angles (cross-chaining), can change gears quickly, and can be adjusted anywhere in between a 22t and 44t equivelant.

If there was one bike in the awards area at the show that epitomizes the idea of a design award, it would probably be the Rafael r-023 Ueberbike. From the driveside it may be easy to overlook if you’re not into tri bikes, but as soon as you take a glance at the non-drive side of the bike it stops you in your tracks…
The great thing about smaller shows like Philly Bike Expo is the laid back atmosphere, where we have time to hear the stories behind more than just the latest and greatest. Last time, Santana’s owner, Bill McCready, gave us a fantastic materials science talk. This time, he had less to say, mainly because this monstrous bike was built in his absence.
Santana leads group tandem tours overseas. On their last trip, while they were nonchalantly letting participants play around on the BionX equipped e-tandem shown at the bottom of this post, his employees were busy welding together this prototype fat bike. The expo was the first time anyone else had really seen it, and it was hard to miss…
In early 2012 when disc brakes were really coming on strong for road and cross, TRP was working on a project called HyWire. Combining the braking power of a full hydraulic system with built in Shimano Di2 shifting compatibility, HyWire was looking like a very attractive option. That was until Shimano went 11 speed and left companies like TRP in the dark. Without support for the new shifting standard the trail for HyWire went cold.
In the mean time TRP has been working on awesome road and cross disc brakes like the Spyre and HyRd, leaving us to think the Di2 project was dead in the water. That is, until we spotted this latest prototype on one of Ben Berden’s Raleigh RXC Pro Discs. Appearing to be a modified version of their HyLex single speed hydraulic levers, it looks like TRP might be closer to an 11 speed Di2/hydraulic lever set than we thought…
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…
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…
