Featuring oversized hollow-forged crank arms and a massive 30-millimeter Praxis™ M-30 spindle cold-forged from 7075 aluminum and precision ground to extremely tight tolerances, Box Two™ M30-P cranks fit frames with European bottom brackets, paired with the same oversized, hollow-forged arms and 104 BCD spider with a flex-resistant ring as our Box One™ M35 cranks. An independent test lab compared a wide range of cranks to both the Box One™ M35 and Box Two™ M30-P cranks. The Box Two™ M30-P cranks proved to be stiffer than anything on the market, being second only to its Box One™ M35 big brother.
Each crankset includes a Praxis™ M30-BSA Threaded Bottom Bracket that is compatible with all BSA European style bottom brackets. For frames with BB86 or BB30/PF30 bottom bracket shells, compatible adapters can be purchased separately from Praxis ™.

I've been riding for years and with different crankset, this one feels way better. Stiffer and smoother. The construction of the cranks seems amazing and i really like the oversized spindle for BMX.
