Sunlite Repair Bottom Bracket – 68x113mm Square Taper, JIS, Threadless for Stripped Shells

Condition: New

The Sunlite 68x113mm Repair Bottom Bracket is a threadless, press-fit solution designed specifically for frames with stripped or damaged bottom bracket shells. Perfect for saving otherwise unusable frames, this bottom bracket utilizes an expanding cup system to securely anchor in place without threads, making it ideal for emergency repairs or cost-effective frame restoration. It uses a square taper spindle compatible with JIS-standard crank arms, and the 113mm spindle length offers a moderate chainline suitable for most hybrid, road, and mountain bikes.
