Obviously i know how to change a BB, What i'm after is the type of bearings or code and supplier of GXP sized bearings.

My BB is starting to creak so rather than replacing the whole units, i was thinking of replacing just the bearings with a good quality possibly ceramic bearing set. They're only press fit so should be easy enough to change?

Anyone done it?

(Eccles i'm looking at you )

Now that's what I'm talking about, repair kits and ceramics.

That is a great price for ceramic bearings, and the postage is good as well. I may have to invest in some.

GPX uses none standard bearings I believe (like Shimano XTR) to try and get you to buy the whole thing again. I believe they are 6804RS 20x32x7mm (the 7mm width is the tricky bit). The enduro ones use a shim I think to make their more standard size fit.
You'll either need something like a blind bearing puller or some careful use of a socket/punch/flat headed screw driver and hammer to get the old bearing out. I've used a headset press to get the new bearings in straight without applying pressure to the inner race.

I knew I could rely on you rob

Changing my bb tonight for a wheels manufacturing one and they have three bearing replacement options Enduro bearings have a 1yr grantee also. I'm fitting mine with my headset press enduro bearings and shim seem like a good option

Right dismantled all ready to be identified. Took one original sram one and one superstar one apart. Quite different for something that does the same job.

When I changed mine I noticed wear on the chain ring bolts from the stinger. It just showed how much play the drive side bearing had

The steel wheel manufacturing one with non ceramic bearings is super plush

Could try these they sell Enduro bearings in this country, I've used them in the past.

Cheers Robert, out of stock

How's the foot/leg now?

There is a bearing place in Maldon. Essex bearings. They may well be able to help.

I forgot them today i was going to take them to a place near one of my offices, stupidly put them in a mug that i've been meaning to take in since xmas. nope, still forgot.
Think i better order a std one just in case i dont get it sorted before the weekend.
