What Is The Diameter Of The Centre

By Magnus

11 Apr 2017

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

SJS Customer Service:

Hi,

This bottom bracket is designed for 68mm cranks only, if you definitely require a 73mm option then the MTB version of this bottom bracket will be suitable. These are SJSC part number 33010.

Thanks.

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.

None

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.

Thanks.
