I put my new Madone on my trainer about a week ago. However I am hitting the chain-stay with shoes every so often. The chain-stay protector that came with the bike was installed maybe a bit too high and is not protecting the chain-stay from the lower side and my hitting the protector is lifting the protector up. So I ordered a new one to install over the old and lower. It says it comes with an alcohol pad to remove dirt grim etc. I have read there is things you can use and not use on carbon, can you use the alcohol pad on Carbon? Also would you recommend removing the old protector first or installing the new over the old. I would think a double thickness though not being double where I need it should not hurt any?
