Can anybody tell me about this? Does it actually have a coil?
I'm rebuilding my friend's MTB and he doesn't want an air sprung fork. But I was looking at a RS Duke and they have Hydra Air ciol system.
Fubar the Duke Race, SL, and XC are all air sprung.
How about the Duke C? According to RS website it is has an air spring and a coil. Which cuts weight but makes it low maintenance and gives a wide range of adjustment options. \
The guy I'm doing this for is a low maintenance maniac, is the Duke C the wrong fork for him?

not that I can explain this very well but... I have the Duke xc and it is as I am told a air shock, you have a small pump to raise the internal pressure, but there is also what seems to be a spring adjustment which you can tighten or loosen to gain rebound time. so maybe there is a small coil inside. It is a excellent suspension fork though, I am very satisfied with it. :)

if it's an air sprung fork, it's usually (not all) higher maintenance...that is if you want it to keep working smoothly. I wonder if the coil is similar to the first generation SID that had a coil negative spring to aid the air spring. If he really wants low maintenance but doesn't mind the weight, tell him to get a coil sprung Marzocchi fork (Atom 80?)...as long as it has boots on the stanctions, he'll be fine for a while..

well it appears to be, in the manual which came with the susp fork, it said to air up the fork to a specified psi according to weight, and to use a thin teflon lub on the fork itself. other then that there are only 2 other adjustments, one for racing the other for rebound. seems pretty simple to me, but I have yet to fully service them.
