CeramicSpeed Coated T74/73 Ceramic Bottom Bracket - for 30mm MTB - T47-73-30 - black

T47 is a standard created by custom frame builders. It’s threaded, has an inner diameter of 47mm, and is 73mm wide. It has the design benefits of being oversized and wide, but also the practical benefits of threads. 

The cups have CeramicSpeed bearings pressed in. The Coated Bearing has CeramicSpeed balls running on a 3-micron thick coating placed on top of hardened-steel races for greater durability and less friction.

This BB is compatible with 73mm frames.

Bottom Bracket tool for installation: BBT-69 (not included).

T74/73 Ceramic Bottom Bracket - In The Box:

  • 2 threaded cups with CeramicSpeed Bearings installed.
  • 2 dust covers.
  • Spacer.
  • CeramicSpeed All Round Grease.

CeramicSpeed Coated Bearings

CeramicSpeed coated products are covered by a lifetime warranty*. The unique coating formula is a metallic layer that covers the bearing races and makes them 75% harder than steel. Thanks to this, they are highly resistant to corrosion and the coating provides an even lower friction than our standard bearings. Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible if you choose the coated version.


* the lifetime warranty covers all coated bearings and OSPW derailleur cages of CeramicSpeed - and this even retroactively to all products purchased from 01.01.2021. The confidence in our own products should be passed on to the customers at this point. Products outside the new warranty terms will continue to be covered by a four-year warranty.
