CeramicSpeed Coated BSA Ceramic Bottom Bracket - BSA-73-DUB - black

Step up to a new and transformed riding experience.

For BSA frames with 73 mm case width and SRAM DUB cranks with 28.99 mm axle.

Threaded MTB bottom brackets are mostly English-threaded, aka BSA, and feature the same threading and the same 34 mm inner diameter, but a wider 73 mm shell. This kit pairs 28.99 mm SRAM DUB spindle cranks to the BSA MTB standard.

Bearings pressed into threaded cups, which are then threaded into the frame are the main components of this kit.

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.
