Praxis 68-5001R Shimano BB30/PF30 Ceramic Pressfit Road Bottom Bracket - 68mm

The Praxis 68-5001R is a ceramic-bearing upgrade of the brand’s press-fit bottom bracket for BB30 and PF30 road frames running Shimano Hollowtech II cranks. It uses the same threaded collet-style system as its steel-bearing sibling to eliminate creaks and improve frame interface durability, but swaps in high-performance ceramic bearings for reduced friction and improved longevity under load. Housed in precision-machined aluminum cups, this BB is built for riders chasing every marginal gain — whether that’s smoother spinning on long climbs or snappier acceleration during high-output efforts. A solid choice for performance-focused road setups where quality and compatibility are non-negotiable.
