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. During the creation of our cranks, we were obsessed with Power delivery AKA pedaling stiffness. To reduce lateral deflection at the bottom bracket we chose to enlarge the spindle and the crank arm’s interfaces. We robbed material from unloaded sections to reinforce these zones of high stress. Not only are you going to be more efficient with power delivery, but you’ll also feel the instant response of acceleration. Seen through another lens, less energy will be required to achieve the same elapsed time.

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. It is possible to add too much stiffness where the rider will not feel the benefits. Going beyond that point simply adds material which is surplus weight. We’ve removed the stabilizer rings from the spider and removed unneeded material from its legs. These cranks are engineered for the smaller-sized racers.
