CeramicSpeed Bottom Bracket, which converts the PF30 standard to fit a 24 mm spindle like Shimano, FSA or Rotor. Available with CeramicSpeed Standard or Coated Bearings, this bottom bracket is suitable for MTB bike frames with a shell measuring 46mm inner diameter. The mounting cups can be red or black.

If you want to install Shimano, FSA or Rotor cranks with 24mm spindles on your off-road bike, this CeramicSpeed BB PF30 Shimano MTB Bottom Bracket not only delivers you the unique mix between low friction and long lifetime, but it also comes as an extremely lightweight system.

To secure the best properties this MTB bottom bracket comes with their special LongLife grease. 

When going off-road, wear and contamination is a risk that you should not have to worry about, the coated version offers extra protection. 

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.
