Installed and went on 2 short rides with the luftkappe before removing. In perfect working order with no signs of wear. I had air shaft issues and had to swap mine with the new debonair unit so I dont need this anymore. Originally $85 + 15 shipping, looking for $65 and can bring to mtbnj ride. Side note, the kit came with a o ring for the air shaft bolt which was used and is not included. Good time to install this is with a rebuild as the rockshox kit comes with the needed o ring.
