Setting up a Sugino RD2 or XD2 crankset on your British-threaded road frame? Need a quality, sealed JIS square taper bottom bracket to mount the arms to? You are in luck. Sugino offers this cost-effective, silky smooth CBBF bottom-bracket in the common 103mm length for most of their square taper road double cranksets.

The CBB series bottom brackets have steel cups, axles and sealed bearings for stiffness, proper installation and long term durability under daily use. The JIS 4-taper spindle will work with any compatible crankset. With it's 1.37x24T( BSA) threading for 68mm bottom bracket shells, the CBB-103 will be the proper bottom bracket for many non-Italian threaded steel road frames from the mid-1970's on. If you aren''t sure what your frame calls for, or what your existing bottom bracket is, you can measure the length of the shell with calipers, as well as the existing square taper spindle. If you need more information beyond that, you should consult with a knowledgeable bike mechanic.

Sugino's commitment to precision and quality means proper installation of this bottom bracket and your preferred crankset will ensure smooth pedaling for many rides to come, with zero service required. Sugino even supplies a pre-applied threadlocking compound to the cups, which we recommend you also use common grease with. The 20-notch interface of the cups is shared with many other options, including Shimano, so a common tool such as the Park BBT-22 or BBT-32 will work perfectly for installation and removal.
