Profile Racing Outboard Bearing Bottom Bracket kit. Outboard Bearings are larger, stiffer, smoother, and more durable than a standard Euro bottom bracket.
Available in various colors. Accepts 19mm spindles.
Installs with Park BBT-9. (Sold in our "Tools" section)
Please note- Since the introduction of these bottom brackets, Profile no longer etches their name or other logos on the BB cups. As we sell through our inventory and order new stock from Profile, bottom brackets may, or may not contain the Profile etchings. Rest assured, ALL of these bottom brackets come to us direct from Profile!
