I'm running into some potential clearance issues. I'm switching a bike from 8spd to 10spd and the front derailleur is very close to the tire, not the cage, the body. I have installed a low clamp SRAM X7 3X10 derailleur, between the body and the rear tire is about 1/4" with an old Cont RaceKing 2.2. Would a Shimano SLX provide more clearance? If I use a high clamp I believe the issue would be worse due to the angle of the seat tube. It's a Trek/Fisher Wahoo 29er frame, same frame as a Marlin/Mamba and perhaps some others.
