The Sunlite SL-26 bottom bracket is a durable, service-focused replacement for bikes using JIS square taper cranksets. Built with robust steel components and sealed bearings, it is designed for reliable, low-maintenance performance on recreational, commuter, and older road or mountain bikes.
A chromoly spindle provides strength and wear resistance, while sealed cartridge bearings ensure smooth rotation and long service life. With a 68mm English-threaded (BSA) shell and a 118mm spindle length, this version is well suited for many double cranksets and narrower chainline applications.
