Can you tell me what the diameter of the centre is?
I want to fit this to a Felt F1 FRD. The frame doesn't have a clip inside it but a slightly smaller diameter so a praxis bb doesn't fit.

SJS Customer Service:

Hi the diameter of the centre is 35mm

Installation

By Tim

Should this be installed with grease, or not necessary because of the o-rings?
How (and how well) are the bearings protected from dirt and water entry?

SJS Customer Service:

Hi,

These bottom brackets do not need to be installed with grease, they can be fitted as they come. The bearings are protected by an additional external seal.

Thanks.

Hi,

You can indeed change the bearings in this bottom bracket adaptor. The old ones can be pressed out and the new ones just need to be pressed in.
