Box Two M30 Crankset Black

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 Two M30-P crankset is a slightly less acute embodiment of our Oversized technology for cranksets. We squeeze in a show-stopping Praxis™ made 30mm that’s been cold-forged from 7075 T6 aluminum and then painstakingly ground to precision. You’ll be relieved to know this will all fit in a European bottom bracket. The crank arms and spider are poached from the Box One M35 model and as a result, you get all that hollow-forged generosity to help you put that power down. These cranks are engineered for the larger-sized racers.
