Wolf Tooth Single Speed Spacer Kit

Wolf Tooth Single Speed Spacer Kit is designed to make dialing in proper chainline on a single speed drivetrain simple, precise, and reliable. Whether you’re converting a geared wheel to single speed or fine-tuning an existing setup, this kit provides the flexibility needed to achieve clean alignment and quiet operation.

The kit includes a carefully selected range of aluminum spacers that can be combined to create multiple common chainlines, allowing compatibility across a wide variety of frames and crank standards. By spacing the cog exactly where it needs to be on the freehub body, drivetrain wear is reduced and pedaling efficiency is improved.

Compatible with any standard HG freehub body, the spacers are machined from lightweight 6061-T6 aluminum for durability without unnecessary weight. An optional stainless steel lockring is available for riders who want a complete, ready-to-install solution with long-term corrosion resistance.
