After finding the lower jockey wheel on my X9 mech has seized (and no amount prising off the seals and soaking in degreaser will free it) i'm bemused by the £30 odd quid wanted for two bits of injection moulded plastic and bearings.

So, I've popped out the bearing with the plan to shove a new one in myself. Finding it hard to read the code on the seals though. Anyone done this before and know A) the bearing code and B) a reliable supplier of bearings?

Cheers

It's been done before, and some-one even mentioned the right bearing but as the search on here is fubar'd I won't be able to find it. The two that have failed on mine where at the end of the jockey wheel life anyways (teeth worn down along with the bearing) and the bearing just fell apart, when I took em out.

Any decent bearing shop would be able to tell you whatyou nee if you supply the the out and inner diameters along with the width (make sure you order a 2RS version though… two rubber seals).

Macgyver,

Check out these BBB replacement sets at £14 delivered.

Friends have used them on SRAM and I have used them for years on Shimano.

Yep I asked this recently. Some useful info on this thread…

I replaced mine with X7 jockeys – cheaper to buy than X9 and the lower one is bushed like the upper, rather than roller balls, so lasts much longer. So much longer I transferred them to a new mech when the old one died.
