The Wheels Mfg PressFit 30 Bottom Bracket is a complete PF30 replacement bottom bracket with super low friction Enduro ABEC 5 Ceramic Hybrid bearings. It is made with alloy cups and fully CNC machined in the USA. Great upgrade to replace a plastic-cupped PF30 bottom bracket and certainly worth a try if you are having creaking issues.

This BB is easy to install, as well as the quietest and sure fitting into your frame. Using the best Silicone Nitride material available, the Grade 5 precision balls and cryogenically treated ABEC 5 races will roll with the least amount of friction possible. Nylon retainers with graphite insure the lowest rolling resistance, while Rheolube grease provides the protection and micro-coated longevity. "LLB" dual lip groove seals and another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.

This adaptable bottom bracket fits PressFit 30 specific frames (46mm ID) with shell widths from 61mm to 86.5mm. It will accept current 30mm spindle cranksets, as well as 24mm and GXP 24/22mm cranksets using Wheels Mfg. adapters.
