OSBB is Specialized's version of the ever-popular Road PressFit30 Standard, except that it is much narrower. The BBInfinite Specialized OSBB Bottom Bracket module works with all 30 mm spindle cranksets on the market, such as the stock FACT/Sworks crankset, Campagnolo OverTorque, and Sram carbon cranks, just to name a few. Our 30mm spindle bottom brackets ship with the special press tools and retaining compounds you'll need. All you need is the press for this specialized OSBB. FEATURES: Ceramitech Bearings: Our Si3n4 hybrid ceramic bearings feature ultra-spherical silicon nitride balls matched to SAE 52100 chrome steel bearing races that have been processed with additional heat treatment and polishing steps. The result is a hybrid-ceramic bearing that lasts longer than any steel bearing with spin performance no steel bearing can rival. We’re so confident in the durability of our Ceramitech bearings that we back them with a Lifetime Bearing Exchange warranty. These bearings feature mid-contact seals for extreme performance and endurance. Each bearing comes lubricated with Kluber Isoflex Topas NB52. Lifetime Warranty. ATTENTION: If you have a 2015 and up Venge, Venge Vias, Tarmac, and many more, you may have cups epoxied into your frame to convert your OSBB Pressfit bike to a BB30 bike.
