Box Vector cranks look beefy, strong and like they should cost a lot more than they really do! Strong and beefy they are for sure but they don’t have a £1000 price tag, actually far from it. Box once again lead with design and back it up with technology, and the Box Vector M35’s are no different, running a 35mm axle diameter when the competition was running 24mm. We are featuring the Junior cranksets, the Vector M30-M on the BMX Race 100 because we know BMX Dad’s love to bling up the kids bikes just as much as their own.

The Box Cranks are available in 3 variants, M30-M, M30-P and the M35.

Vector M30-M, Featuring beefy hollow-forged crank arms and a massive 30-millimetre Praxis™ M-30 spindle cold-forged from 7075 aluminium and precision ground to extremely tight tolerances, the Vector M30-M Crankset is the absolute stiffest junior BMX crankset available today. A precision CNC-machined chromoly/alloy self-extracting crank bolt system makes installation and removal a snap.
Lengths – 145, 150, or 155mm

Vector M30-P cranks have a super-stiff, cold-forged, 30-millimetre, 7075 aluminium 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.
