Shimano BB ALPHA Bottom Bracket Adverse Conditions Service Kit

The CeramicSpeed Shimano BB ALPHA Bottom Bracket Adverse Conditions Service Kit is a targeted refresh kit for riders who put miles on their drivetrain in wet, gritty, or high-contamination conditions. By replacing the wear-and-tear sealing components and renewing grease, it helps the CeramicSpeed BB ALPHA maintain smooth rotation and consistent protection around the bearings—without replacing the entire bottom bracket.

• Adverse-conditions sealing refresh - Replaces the primary wear items that help keep water and grit out, supporting quieter, more consistent performance over time
• Complete kit for service - Includes (2) BB ALPHA seals, (2) BB ALPHA bearing dust covers, and (1) CeramicSpeed Long Life Grease (5 ml) for a straightforward maintenance reset
• BB ALPHA + Shimano 24 mm spindle compatibility - Correct replacement parts for maintaining a BB ALPHA bottom bracket built around a 24 mm spindle in adverse conditions
