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. 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.
“At BOX, we believe the Vector M35s with the Praxis, M35, 35-millimeter spindle is the way to go for any serious BMX racer, and we try to push anyone in that direction. But we recognize that not everyone has a BB30/PF30 frame, so we developed the M30-Ps. While the M35 Vectors are the ultimate BMX race crank, the M30-Ps are still stiffer than anything else out there,” said Michael Gamstetter, BOX’s design director.
Like the original M-35 cranks, the M30-Ps come in matte black with laser-etched graphics and come in 175, 177.5 and 180 millimetre lengths.
