I used to think that was just a crock of malarki until I stuffed some new Enduro seals in my Boxxer. The stiction was enough to make me hate the Boxxer. Factory jobbies on the way.
So I could easily see how slippery silver would improve the ride.
Enduro seals suck nards. Rock Shox in everything even in Fox. Always wanted to do some modding of my seals on my boxxer but I am lazy. I got to push a boxxer with the DLC and it isn't even funny how smooth it is. Out on a trail may be another but for a parking lot test... Dayum.
