Could rubber parts on bike rack damage the rear shock? I have Specialized Stumpjumper Evo FSR and as all the FSR frames its' shock is underneath the top tube. Now the issue that the only option to put the bike on the rack is to put the shock shaft on the rubber U that's on the rack. The question is, can I do something to ensure avoiding scratching shock shaft? Or the only way is to get a new rack?
You can purchase a rack adapter thats primary use is for mixte, womens bikes or bike with angled top tubes. It is a removeable bar that attaches to the seatpost on one end and then attaches between the stem and the headset top bearing at the other end. You then hang the bike on the rack by the adapter.
