Ridden to a 2013 World Championships by Caroline Buchanan, a silver medal by Marc Willers and bronze by Manon Valentino, Box One M35 Cranks have proven themselves as the go-to choice for elite BMX racers. What makes these BMX cranks so special is that they are the world’s first with a Praxis 35-millimetre external bottom bracket system. Hollow forged crank arms and a massive 35 millimeter Praxis spindle cold-forged from 7075 aluminum make this the absolute stiffest BMX race crank on the market today, period. A precision CNC-machined chromoly/alloy self-extracting crank bolt system round out the system, making installation and removal a snap. Fits frames with BB30/PF30 bottom shells. M35 cranks will not fit frames with BSA (Euro), BB86 or T47 bottom bracket shells. ###section### Product Specs Type:2pc Spindle Diameter:35mm Includes BB Bearings:No Weight:750g ###shogun-image-section###

Traditional chainring geometry forces a compromise between up and down shift locations, none of which have ideal timing. In fact, half of the possible locations are skipped on each crank revolution. The more shift locations you try to incorporate, the worse the timing compromise will be: either your chain jams, causing chain suck, or the chain just fails to shift and runs across the top of the rings until it hits the next shift location. Those days are over with X-Glide. X-Glide is the common denominator that gives XX its unmatched shifting performance. With the X-Glide, all four upshift locations are identical and can be picked up by any outer link. The result? Up and downshift locations have perfect timing for an almost instant shift - even under load.Manufacturer's Part Numbers: 90390210005 / 5056389548195Buy Truvativ Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
