Hey guys, what does everyone do to protect the area right below the seat collar from cable rub? My rear derailleur housing rubs right there since it moves with the suspension. I've put those Sram rubber boots around the housing and they lasted a few weeks. Any kind of stick on thing will get rubbed through pretty quickly as well. What would be ideal would be some kind of plastic that snaps around the seattube. Any of you guys engineered something?
