Profile Racing Race Cranks 175mm Bossless Chromoly 3-Piece BMX Crankset
The legendary Profile Racing Race Bossless Crankset is American-made 3-piece BMX crank system engineered for maximum strength, reliability, and performance.
Profile Bossless, or No Boss cranks, are exactly the same as the Race Cranks, except they don't have a boss to bolt a sprocket onto them, they require a Spline Drive Sprocket or Spider. They can be used for left or right hand drive.
Originally designed for BMX racing, the Profile Race cranks are the benchmark for BMX freestyle, and are often used for MTB as well. The Profile Race Cranks deliver exceptional performance thanks to heat-treated chromoly construction and Profile’s proven 19mm 48 spline interface.
This crankset includes everything required to run Profile cranks — except the bottom bracket, allowing riders to choose their preferred BB standard.
