Do work! The bottom one fits a treat
£2.99 from crc
Tried the top one as well?
Is it the top one that's supposed to be problematic?
Thought x9 had an off-set guide wheel and the jockey was "normal" ?

It's the bottom one, though it's really not too bad if you pop the seals off the bearing and put a more reasonable amount of grease in there.
As i keep saying its the bushings that grind and seize NOT the bearing underneath
Yes, it's the bottom one that always seizes up (and can be cured by disassembling, degreasing and re-greasing) - but I meant isn't the top one the awkward shape?
I assume that because people say the Tacx ones don't fit, but a replacement bottom wheel was fine on mine (haven;t needed to replace a top wheel yet on 3 mechs, touch wood).
my solution was to get some SKF bearings with the double seal. No problems yet.
BBB do replacement jockey wheel sets to fit X7/X9/X0. They're £9.99 a pair I've had one jockey seize up after a mind-bogglingly muddy ride around Bath in June a couple of years ago, when my (then) 32lb hardtail doubled in weight and the wheels stopped going round! A couple of days later I went to ride it and the gears just jumped. On dismantling them I found mud forced right behind the seals on one jockey. A quick soak in hot water and a scrubbing with a toothbrush got things moving, a squirt with a grease gun and then back on the bike. Still going round, like it has for six years.
the top pulley has an eccentric bolt (i.e. it is mounted off centre) whereas the lower pully is same as shimano/BBB/Tacx etc.
strange that the X0 runs normal jockey wheels both with centre mounted bolts.
