Disassembling Roadmaster bicycle shaped object. Crank has 99 mfg date and mfg in Mexico,
so maybe one of last bikes before Pacific buyout?

More dirt and sand than grease in BB.

Pulled the fork off the RockRat for the first time in over 25 years. I believe the hard crusty stuff was grease at one point.

Does anyone think this looks salvageable? Made me very sad when I opened it up. Poor baby, stuck with ME for an owner

yeah it's good. Use a brass wire brush and light oil like 3 in 1 or Rem Oil for guns on the threads, but any oil is better than none when wire brushing. Steel wool and metal polish or a brass brush and oil on the fork stem and an all new head set as the bottom race looks like it could be bad but it might need to just be cleaned. Any pitting, gouging or looseness on the race and it's no good. After brushing you can clean up the threads with a top race and oil if you don't have a thread chaser. Should be good for another 25 years.

Yeah, it's the guts of the shock I'm worried about. Out of production for 25 years, and Specialized isn't famous for supporting old products. The oil has been in there since new, and it's not leaking, so I'm hoping that the seals are still useable.

Is it elastomer suspension? If so, there are cheap ways to replace them. I can't remember what they are, but it can be search-engined and I think there's even youtube videos. I was going to do this to my old mountain bike, but my ex's kid needed a bike and that was the "coolest" bike I had to give away that a teenage boy wouldn't mind riding. I wish I had the pink rocket bike at the time and could have pranked him with thinking I was giving him that!

No elastomers, oil and air. It's the Specialized version of a Mag21

This will eventually be pulled apart, with mods to add a few mm of travel, maybe bump it up to a whopping 60 mm! Watch for the post on my RockRat thread. My antics should be pretty comical, I expect a bike mess
