Re: My Jamis Dakar I picked up at the swap meet...it looks like the sellers just recently either built it up from parts or it was beaten up in its former life. The rear wheel needs to be trued...it's at least 1/2" outta whack. The rear hydraulic brake hose or tube or whatever is about 6" too long...probably robbed from a larger bike. The front caliper is way too tight, and I don't know squat about adjusting disc calipers. The rear caliper is way too loose, and I think I need to re-bleed the brakes...which I don't know how to do. Both derailleurs are terribly maladjusted.
Other than that, it's a fantastic bike.
Theoretically, I should have known this, but when I was checking it out, it only had the front tire on it, and that was flat. The rear was still in the back of the truck...so I couldn't test ride it. I figured I could fix whatever was wrong with it.
