Box Components Vector M30-P Race Cranks

The Vector M30-P cranks have a super-stiff, cold-forged, 30mm, 7075 aluminium alloy, Praxis M30 spindle that fits frames with European bottom brackets, paired with the oversize hollow-forged arms and 104 BCD spider.

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 Praxis and its dealers.

An independent test lab compared a wide range of cranks to the Vector M30-P cranks and proved to be stiffer than anything on the market.
