The Box Two M30-P Cranks are engineered using Box’s Oversize Technology design philosophy to provide the ultimate in stiffness and the low end of the weight curve. These being Box Two they have not gone full zealot with the Oversize, but they have included a Praxis made 30mm aluminum alloy spindle with the aim of increasing pedaling stiffness to the max. Fun fact: the crank arms and spider are actually from the Box One M35 Crank, so you’ll have that going for you...which is nice.
