Yep - RC36 require a crown race shim and mine came without one as well! Took me a week of head scratching to realise and a few weeks to find a 1 1/8th version! Eventually realised that Tim (justbackdated) had some and he supplied mine and plenty of other very good advice too! Might be worth booking them in for a service with him, tbh, to check all is well, has the appropriate 500 grades of loctite applied in the relevant places and everything is torqued up properly (carbon legs and all that) and everything is still bonded correctly. Also RC7 grease isn't always easy to locate - ask Tim for some while you're at it. Apparently PACE forks like to be nicely maintained after every ride. Nice forks though and look gorgeous.
I have a spare 1 1/4 shim somewhere, but from the sound of it that won't be much use.

Wanted: lots of things. But my money has all gone... for now...
