White Industries ENO Single Freewheel

White Industries ENO freewheels are a benchmark for smooth, reliable single-speed riding. Precision-machined from high-quality materials with nickel-plated, hardened-steel internals, they feature three pawls and a 36-point engagement for quick, positive power transfer. Fully rebuildable and made for long-term durability, they’re a premium upgrade for any single-speed drivetrain.

Note that White Industries has discontinued the red lockring, so we are adopting the blue lockring as our default color.
