Description

Rotor BB30 bottom bracket converter. With this bottom bracket converter you can mount a regular BB24 crankset in a BB30 frame. This set reduces the diameter of the bottom bracket from 30mm to 24mm. A new advanced labyrinth seal ensure a smooth rotation of the cranks. The bearings are well protected against dust, water, and mud. New cups, completely black.

Suitable for all conventional BB24 cranks like the Rotor, Shimano, and all Shimano-compatible brands. For a 68mm wide bottom bracket. Once assembled, the distance between the outer points of the bearings measures 91mm. Mountable with Shimano TL-FC32 bracket tool. Tighten to 40 Nm.

3 / 5

Best on-line price for this BB.

- Keith 9 April 2017

Care is needed to ensure the plastic covers protecting the bearings does not come off when pushing the crank axle through the bottom bracket. I've had to buy two of these BBs, because when fitting the first one a plastic cover came off and when re-fitting it it crumpled. I've taken a cover off the second BB to replace the crumpled one. The low rating is due to the problems with installation. (I've installed many BB and I am a competent mechanic and this has been the first I've had to buy a second BB for spares.) Operationally it's a great BB and runs smooth.

5 / 5
