Sunlite SL-55 Square Taper JIS 68x118 Spindle Alloy Cups Sealed Bearings BSA Bottom Bracket

Available from Good Weather Bicycle when we last checked. Sold from the shop’s own store; the price there is the one that counts.

The step up from the SL-26. Same idea, alloy cups instead of steel, which shaves a little weight and makes it a straight swap for a Shimano UN55 when you cannot get one. Sealed cartridge, forged steel body, chromoly spindle. A good call for a nice touring or randonneur build that still runs square taper and deserves better than the entry-level part. Shell: 68mm, English / BSA Spindle: 118mm, square taper JIS, chromoly Cups: alloy Sealed cartridge bearings Weight: roughly 295g MPN: 17138
