Just noticed whilst tightening my rear mech that the bottom jockey wheel on my XT derailer Is kinda chewed up with a couple of dodgy teeth on It . The gears are slipping a bit which could obviously be a few things. My bike will probably be used as a second / winter bike fairly soon so was thinking of just getting a new lower jockey wheel . What would be the best one to go for and I presume they are easy to fit .?
Stanfree,
Just get a £10 pair of BBB jockeys from Dotbike and the job is done.
Under half the Shimano XT price and highly rated....you need to go XTR to get a cartridge bearing Guide Pulley!

I take It they are part number 3992-13191 BBB Pair Roller Boys Jockey Wheels?.
Thanks
Stanfree
The 3992-13190, 191 and 192 are all OK for Shimano 9-speed mechs.
I personally would not pay the extra for the ceramic bearing models.
I would remove the rubber seal and fully pack them with grease before fitting tho'.

just got some GUB cartridge bearing cnc'd alloy jockeys in red off some bloke in china for 8quid (ebay, other colours available) cant comment on quality though, not used them yet, failing that CRC have slx/lx ones for about the same and,, im not 100% sure,, i think you can mod them with a drill or file to fit your old XT ceramic sleeve/bearing internals,,, have done this myself on old xt mechs with no probs, before the advent of the shadow mechs though.
