Hollow bottom bracket bearing ordering

[skudupnorth]

Need some help on how I size these new fangled bottom bracket bearings for my Boardman SC Comp fixie.
Checked on the usual online suppliers and no numbers match what I have on the original unit.
This has lasted 7 years and has finally given up !
So, how do I size this lump ?

That has BSA (British thread) marked on it so that’s your answer. You buy the entire unit as shown. Don’t over tighten.

So all bearing diameter sizes are the same, just go off the British thread ? Thanks for that, it’s the first time I have had to order one

The actual bearing sits inside the adapter and it’s this that has to have the correct thread.

I’ll measure the length. Many thanks for your advice chaps, damn this modern stuff
It’s as bad as modern cars which I why I drive a 23 year old car with no gizmos

Its a SRAM GXP bottom bracket cups - you will need to get the same type to fit your cranks

SRAM GXP bottom bracket

GXP differs from the likes of Hollowtech 2 as the spindle is stepped - 24mm dia drive side and 22mm dia non-drive - SRAM-Truvativ.
Would be very surprised if not 68mm.
