Jockey wheels seized

The jockey wheels on my MTB have seized up, after leaving the bike
unused for about a month (been using the new road bike). I've taken
them out but there doesn't seem to be anyway of getting at the
bearings. A bike shop put them on for me, they're Tacx ones, about last
March. Given that the shop also initially put on an 8 speed chain I am
quite willing to believe that they're the wrong jockeys too.

I've looked for replacements, preferably not Tacx, but wiggle seems to
think that the Shimano LX "lower tension pulley" is no longer
available! I've not found them in stock anywhere else.

Can anyone suggest somewhere that does have them in, or could I put
SRAM (or other make) on instead?

Just fit the stock Shimano parts. They work much better than the ones
with fancy bearings IME. Get them from

You can't put SRAM jockeys in a Shimano mech - they're quite different.
I would use Tacx ones - and maintain them properly. You need to strip the
deraileur on a mountain bike fairly regularly anyway - they get full of
****e very quickly.

Better still junk the Shimano mech and put a SRAM one on, although you'll
need to change the shifter too. SRAM mechs index more accurately because
of the actuation ratio (this applies across the whole range, from
cheapest to most expensive), have a better cable lead design, and
price-for-price are better quality. Last year at the World Cup, most of
the pro teams were using SRAM (I didn't actually see any pros using
Shimano, but there may have been one or two).

I tried Tacx many years ago and they were fine, however in more recent years
I fitted some and they seized very quickly, a friend had the same problem.
Personally I prefer the older XT set up of ceramic upper and steel lower
bearings but these have now changed to a ceramic upper and ball bearing
lower, in fairness I've got through several sets of these without ball
bearing failure and they are still my choice.

An expensive way to sort out jammed aftermarket jockey wheels.

Pro teams go with whatever the sponsor pays for. I've not had indexing
problems with Shimano over many years. I have had problems with jammed
aftermarket jockey wheels but never with the original Shimano ones.

I prefer the simple bushing bearing. Its not as if the bearing quality
there is going to change the drive chain efficiency noticeably unless
they jam up and the bushing bearings are pretty much indestructible in
that respect.
