I figure this must be a common Ibis issue with their current linkage design. This is on a Ripmo AF with Assegai's which throw rocks constantly. Rocks get into this spot and get pinched by the linkage. I ride in the Sierra's so there's rocks everywhere. Does anyone have a fix for this? I was thinking of using some frame tape to just bridge across the area. I've heard of using a piece of foam but I think foam would just trap dirt and then constantly rub the dirt against the frame, causing damage as well.
