SBI PF30, Carbon OSBB
Specialized's (SBI) PF30 and OSBB standards are unique to Specialized bikes. In other words the PF30 on a Specialized is not the same PFC30 on another bike. If you have a PF30 equiped Specialized this bottom bracket will work on your frame. If you have an OSBB frame make sure youhave a carbon OSBB.
