Octane One 2PCS Crankset Pro

The lightest & strongest & coolest Octane One tubular chromoly crankset comes in a popular & trendy two piece format. 170mm crank arms made of high quality seamless 4130 chromoly tubing with full heat-treatment.

The 19mm diameter hollow axle with 48 micro-splines eliminates the need of pinch-bolts making this crank arm lighter and gives it a clean look. 48 splines provide a large area of contact & eliminate the stress points. This makes the connection more reliable and durable. Right side sprocket mount only – this is a MTB set.

Will accept any BMX sprocket with standard 15/16” or 19mm central hole and standard mounting hole (23t and bigger sprocket sizes). The chain line is perfect for MTB! Great looking square crank arm shape. For 2014 offered without bottom bracket/bb available separately.
