I have a 1 year old Trek 820 mountain bike with an RST 191 front fork. I know that the fork is a low-end jobbie, but, hey, I got the bike for free as an airline frequent-flyer premium, so I can't complain. I mostly use this bike as an "unimproved-roadie" - riding on gravel roads, MUPs, etc., as opposed to "real" mountain biking. I have a feeling that the fork will probably hold up OK under this duty.
I've Googled for info on this fork, and other than hit after hit of people saying how cr@ppy this fork is, I can't find any sort of on-line manual that applies.
I have seen where mountain bike forks require maintenance, but Trek sent absolutely nada maintenance info with this bike. Outside of applying a little grease on the telescoping part and keeping it wiped clean of dirt and grit, what should I do to maintain/adjust this fork - at least until I retire it?
