I Tried to put a 110/100-12 perelli sl26 tire on my bike with RCM forks but the tire does not clear the forks. I have fast ace clamps and i was wondering if the fast ace clamps were narrower than the RCM clamps? The way it looks I dont think I would clear a 90/90-12 tire. Can someone with RCM forks mesure the distance between the legs so I can copmare it to mine. Can anyone help please.
