All Box One and Two cranksets are engineered and crafted using our Oversized Technology. We all know that there is no use pushing hard on your pedals if you can’t deliver most of that power to the rear wheel. To reduce lateral deflection at the bottom bracket the spindle has been enlarged and the crank arm interface. Not only are you going to be more efficient with power delivery, but you’ll also feel the instant response of acceleration. Key differences: The Box One M30 crankset is just as tyrannical as its big brother the Box One M35. Since it's designed for the smaller rider, the now 30mm spindle is as extreme to a smaller rider as the 35mm is to a burly world champion. The crank arms are hollow-forged but reduced in size for their application. These cranks are engineered for the smaller-sized racers.
