The Vector M30-P cranks have a super-stiff, cold-forged, 30-millimeter, 7075 aluminium alloy, Praxis M30 spindle that fits frames with European bottom brackets, paired with the exact same oversize hollow-forged arms and 104 BCD spider as the M35 Vector cranks.
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 and available though Praxix and its dealers.
An independent test lab compared a wide range of cranks to the Vector M35 and the Vector M30-P cranks. Both proved to be stiffer than anything on the market, with the M35s about 10 percent stronger than the M30-Ps.
NOTE: RaceFace BB92 Bootom Bracket will not work with this Crankset
