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 M35 crankset takes the oversized spindle action to an extreme with a colossal 35mm diameter cross-section courtesy of Praxis™. That dimension might seem massive, but we’ve also employed the use of cold-forged 7075 T6 aluminum. That's an alloy that delivers low mass but that also flirts with the toughness of steel. We then grind that spindle with the kind exactitude you’d expect from medical equipment. The very prominent crank arms are hollow-forged with much of the wall thicknesses pushed to high-stress zones. A stabilizer ring acts as an anti-twist brace between spider legs. A precision CNC-machined Chromoly/alloy self-extracting crank bolt system secures the package. Remember, you’ll need a modern frame to cope with this kind of technology.
