I had to install mine twice because the holes used to thread the skin can be very hard to distinguish between the perforated sections on the black skin. I enlarged the holes before the second install, helped very much. Be sure to count the holes in the rear of a spoke when skipping in the front so you match up exactly. If you don't you'll end up with extra leather bunched up. Take your time, enlarge holes first and count stitches and it should go ok. My 2nd time around was much easier.
Skeptical at first. I've used the slip on style covers (different brand) and the very old rubber lace up style and was not impressed with either. This cover is a pleasant surprise. After following the enclosed instructions carefully, the end result looks just like the factory wrap on the wheel. ( I was hoping to get a more "hand filling" feel from the cover and that accomplished that in spades. It did take me the bulk of the hour, but for the end result, it was an hour well spent.
