DUB bottom brackets seem a bit fragile, I don't like wasting resources on throwing away the cups if I can replace the bearings. Have 5 bikes with BSA DUB, so it is worth a try!

Anyone tried this and can recommend a bearing puller and replacement bearings?

Yes, I think.

Got a nukeproof dub bb on the commuter, currently keeping the bearings alive by popping the seals and squirting in fresh grease.

I do have some fresh bearings I picked up from Kinetic but haven't got the puller to do the job yet.

I've bought from these guys before and been satisfied so will probably go to them for puller and press.

I found them and asked about which one might fit. Good to know they are recommended. Thanks

Do you know the bearing size you purchased?

I believe these are specific to nukeproof and whatever they're rebranded from

KINETICBIKEBEARINGS.COM "https://www.kineticbikebearings.com/mr2940h6-8-2rs-bottom-bracket-bearing-nukeproof.html"

You can Google the specific BBs you have and see if there's an online source for the bearing specs, that's how I found the above. 🙂
