I want to have a go at replacing the BB on my Singular Swift. Never done this before so was wondering what BB I need that will fit my XT cranks and will fit the Swifts EBB? What is a good BB?

T.I.A

Assuming you mean an external BB then pretty much any Shimano compatible mtb one will work. As it goes, I have a Superstar Components one on my swift and despite me expecting it to die quickly, it’s going strong three years on.

Top tip is to make sure that when you’re fitting the crank, don’t over tension the cranks – just enough to remove play.

XT? Hope

the EBB takes a standard 24mm external cup BB or for that matter a proper english thread square taper job, though assume you have through axle hollowtech 11 XT cranks?

Get an MTB BB….the road versions are limited to a 68mm shell and would need a different spacer to fit the XT cranks.

What they said, SLX/XT/XTR all fit.

Thanks for your help chaps. I’ll get on to this asap. I’m running single speed at the moment so a strong bb would be nice for peace of mind.

If it’s an external, I’d go with a Hope – contrary to Clubber’s experience I saw a SuperStar one disintegrate 3 laps into a 12 hour, so YMMV – they are cheap though.
I got a ceramic Hope and it’s been silky for 18 months, destroyed an XT in about 4.

How do I know if it’s an external? I’m not up to speed with bottom brackets :-S
