Hello everyone, I picked up a bike with Rock Shox Magnesium forks, Mag 20. After finally finding that the air fill is the center screw on the dampening dial (three local LBS did not know this even after seeing the bike, thanks to Jesus I found a thread with the Rock Shox service manuals). I'd like to know how much air to add. Air starts to escape from the shock as soon as I remove the air needle, but I've managed to set the screw under a little pressure but I can't tell how much. Not nearly as much as indicated in the Mag 21 manual. Most of the air escapes before I can set the air inlet screw. Must I set the air inlet screw faster or is there some way to actually tell how much air is in the Mag 20 shock?
I'm feeling very tentative about riding this bike after going over the handle bars during my first test ride when the shocks bottomed out on top of the front wheel, causing the front wheel to come to a abrupt stop. I would hate to have the air leak out during a ride and get hurt.
I'm not sure if I have enough air and oil in the shock and certainly don't want another trip over the handle bars. Help this Noob out, and tell me what I need to know about using and maintaining.these shocks.
After adding air the shocks SEEM ok. They do not bottom out and when I put my full weight of 208lbs. on the handle bars. I'm hopping they will not bottom out after taking a bump or a jump hard and fast. The bike has 26" x 2.2" knobby tires.
Does anyone have a link to the Mag 20 User's manual?
After thinking about the Rock Shox bottoming out on top of the tire, this fork appears very dangerous, if the one that I have is installed correctly. If the shock losses pressure the rider can be ejected from the bike, if the fork or fork brace bottoms out on the tire, resulting in serious injury or death. Please see photo.
Thanks in advance for your help,
