Easton BSA 68mm Bottom BracketThe Easton BSA 68mm Bottom Bracket was made to work with their 30mm Cinch interface system. The Cinch system uses a 30mm spindle to provide a stiffer bottom bracket/crankset interface, but previously this would limit you to BB30/PF30 frames, not with Cinch! These new BSA 30 bottom brackets will allow you to fit your 30mm spindle crankset in a standard threaded bottom bracket. Don't let your bottom bracket shell width keep you from experiencing 30mm spindles!SpecsStandard 6806 retainer bearingsBearings are factory filled with Phil wood greaseCups are machined for a high tolerance frame fitIncludes an industry exclusive inner sleeve to protect against water ingest from inside your frame | Easton BSA 68/73 Bottom Bracket BSA 68mm, 30mm Spindle
