Box Vector Cranks Black 35Mm Spindle (Bb30 Required)
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.
Vector cranks only fit frames with PF30 or BB30 bottom bracket shells. Meets or exceeds ENBMX Category 1 standards.
