Box Two M30-P Cranks



The Box Two M30-P cranks are made to be strong as an ox and have a super-stiff feel!

The 'P' in the M30-P stands for 'Pro', so these are the pro sized crank lengths.

Featuring a cold-forged, 30mm, 7075 aluminium alloy, Praxis M30 spindle that is paired with the same oversized crank arms and 104 BCD spider as the 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. Both systems proved to be stiffer than anything on the market.

Each crankset includes a Praxis™ M30-BSA Threaded Bottom Bracket that is compatible with all European style bottom brackets.
