Box Vector Cranks

BOX Vector Crank

Ridden to a 2013 World Championships by Caroline Buchanan, a silver medal by Marc Willers and bronze by Manon Valentino, (In all there were four Vector cranksets in Elite Mains at the 2013 Worlds.) the Vector crank is the world’s first BMX crank with a Praxis 35-millimeter external bottom bracket and oversize aluminum spindle, making them about as stiff a BMX race crank as you can get anywhere, period.

Besides an innovative bottom bracket that boosts bearing longevity and stiffness, Vector cranks also have hollow-forged arms. Hollow forging results in hollow crank arms that are stiffer and lighter than any solid crank.
The fully CNC-machined 6061-T6 aluminum alloy BB30/PF30 bottom bracket is fitted with precision sealed bearings for smooth free-spinning pedaling performance. A precision CNC-machined chromoly/alloy self-extracting crank bolt system makes installation and removal a snap.

They are available in matte black with laser-etched graphics in 175, 177.5 and 180 lengths. Vector cranks only fit frames with PF30 or BB30 bottom bracket shells. Meets or exceeds ENBMX Category 1 standards. MSRP: $399
