The tungsten alloy sleeve spacer replaces the aluminum sleeve spacer in front BST wheels. The spacer mounts between the front wheel bearings (part of the front wheel assembly) helping to prevent wheelies under acceleration. Since the spacer discreetly mounts between the bearings, it does not affect the acceleration advantages of having lightweight carbon fiber wheels. By mounting in front of the bike’s center of gravity, the rider can leave the starting line faster resulting in lower ET’s.

Meets XDA, Man Cup, and NHDRO Real Street and Pro Street specifications. Completely hidden and undetectable, this spacer is designed to function with BST carbon fiber front wheels only. No wheel modifications required, reuse of ceramic wheel bearings is not recommended.
