CeramicSpeed MTB Bottom Bracket that combines a PF30 frame with SRAM or Quarq GXP 24/22.2mm spindled cranks.

Suitable for all off-road frames that feature a shell of 46mm inner diameter. Cups available in red or black and bearing, and choice of CeramicSpeed either standard or coated.

Run your favourite GXP-spindled cranks with the smooth CeramicSpeed PF30 Bottom Bracket to enjoy the technical tracks and the off-road rides on your MTB frame.

This bottom bracket is fitted with the high quality CeramicSpeed Bearings that deliver low friction and 3-5 times longer lifetime than standard steel bearings usually used in cycling. To secure the best properties this MTB bottom bracket comes with our special LongLife grease.

The perfect choice for your MTB frameset are the CeramicSpeed Coated Bearings as they have increased resistance to the damaging effects of corrosion coming from water, dirt, or other contaminating foreign objects.

Did you know that this product has a lifetime warranty? That’s right: as of September 1, 2021, all CeramicSpeed ‘Coated’ products and OSPW cages (purchased after January 1, 2021) are covered for life -- that’s how confident CeramicSpeed are in the durability of their products.
