Vector M30-P cranks have a super-stiff, cold-forged, 30-millimeter, 7075 aluminum alloy, Praxis™ M30 spindle that fits frames with European bottom brackets, paired with the same oversized, hollow-forged arms and 104 BCD spider as our Vector M35 cranks. An independent test lab compared a wide range of cranks to both the Vector M35 and Vector M30-P cranks. Both Vectors proved to be stiffer than anything on the market, with the M35's coming in at about 10 percent stronger than the M30-P's.
The M30-Ps include a Praxis™ external, BSA bottom bracket that fits frames with European bottom bracket shells. Compatible Praxis™ BB86/92 and BB30/PF30 bottom brackets are sold separately from Praxis™ and other dealers.
Please note: The installation guide from Praxis makes reference to bottom bracket spacers, but these are only required for MTB frames. Everything needed to run these cranks with BMX frames is included in the box. Also, do not use pedal washers when installing pedals onto these cranks. Vector cranks were designed to be used without pedal washers.
