About This Product

The Box One M30-M Cranks, as with most of Box’s higher end offerings, follows in the Oversized Technology design philosophy. In designing these products, Box moves material from less stressed areas to areas of higher stress, thereby achieving greater stiffness without adding any extra weight. The result of all this is that you will have a more instant response when pedaling. More efficient power delivery is the goal and Box has really achieved it with these cranks. A note on sizing: These 30mm spindle cranks are designed for smaller-sized racers. If your rider is bigger, then opt for the 35mm spindle cranks.
