I just bought a 1999 Trek 820 MB off Craigslist with the intention of
getting a good deal on a used bike. Wal-Mart was not an option for me.
He said the bike has been hanging on his wall for years and has seen little use.
The chain has surface rust and the tips of the gears have some as well.
There is no lube on the gears or chain, and it makes a clicking sound like it's
trying to shift gears. The left grip slides off when riding too.
What maintainence do I need to do in order to bring this bike up to snuff?
BTW, I picked it up for $120. Good deal, or not??
