i bet if you phone royce ,cliff will sort you out, he's not far from me and has always been helpful to us as a shop, top bloke. tip though, massage his ego abit! he likes it!
remember, you never heard of x type or hollowtech 2! and shimano is the bastion of evil! and you'll be using his stuff forever and ever till you go off to the trail in the heaven!
Did you ever track one of these down? I need one too, for my RTS.
A friend of mine was telling me that Ben Haywards in town used to stock Royce stuff, and that it might be worth asking them if they still had any tools knocking around their workshop.
