I cracked the guide pulley on my XTR derailleur and had to rob an old XT G-pulley off an 8spd Trek. The XTR uses an 11 tooth and the XT, a 10 tooth. Are they compatable? The XT uses a ceramic bushing while the XTR appears to be a sealed bearing. It seems to work well enough around the yard but I have not had it on the trails yet. Why did Shimano change to 11 teeth? Thanks.

I take that to mean that they are interchangable? Thanks
