I bought this tank a few months back after i bent the swing arm mount on my Ironhorse Maverick 2.0. there was only a few hundred dollars difference between the RM-7 and the repairs needed to straighten and reenforce the IHs swing arm pivot. so i put all the bits on an Ironhorse Quantum II frame to use as an extra bike.

i was told that the RM-7 weighing in in the mid to high 40lbs range was damn near indestructible which was a huge selling point for me cause im short, fat, and not very light on my feet. So far ive replaced the cassette, chain, derailleur and shifter, bled/replaced the brake fluid, and done a once over to make sure everything is lubed, tight, and doesn't have any play. so far i love it. im curious if anyone more familiar with these has any suggestions on what else i might need to replace/take a close look at being that it is over 10 years old.

specs:
year/model:2003 Rocky Mountain RM-7 FR
forks: Marzocchi Monster Triple
rear shock: Fox Vanilla
handlebars: Race Face respond 785mm
wheels: OEM Rocky Mountain
crank set: Race Face 36t
cassette: Shimano XT 11-36
shifter: Shimano Zee
rear derailleur: Shimano Zee
brakes: Hayes hydraulic (g1/g2?) 203mm rotors

on with the pics!

Get in touch with a local machinist to make you some more dogbone links. I have a good friend in the industry who rode an RM-7 for many years until his business took off. He made his own dogbone links because they developed slop so fast. If I recall, he re-did his whole linkage setup 2-3 times a year. (He is an extremely aggressive rider though, who rides every day all summer). Rocky Mountain should have shipped those RM7s with a 6-pack of dogbone links, lol. The culprit was a very high leverage ratio, if I recall. Great-feeling suspension though! Usually they didn't end up with side-to-side slop, just vertical play (which got REALLY bad if you kept riding the bike).

Also, I would consider replacing that Monster T as well. I used to run a 2001 Monster, which was bad enough, weight-wise (otherwise a very nice fork for its time). Then, for some reason, in 2003, Marzocchi decided that the original 9.5 pound design of the Monster wasn't heavy enough, so they added 4 pounds to it and made it way taller. :)
There is no reason to run such a beast of a fork when you can get better performance and save approx. 7 pounds off the front end of your bike with basically any modern DH fork.

i have a mill and lathe at work so ill take a crack at making a new one when the time comes or mill out the ends and make bronze bushings. i checked out the links there is zero play in any of it. by "dog bone" are you referring to . the vertical piece from the swing arm to the two pieces that connect to the shock?
