I've got the same recommendation as Faust a few posts up. I still have my $900 2013 Trek Mamba hanging in the garage. Rides great, but also is in need of at least a fork seal job. I haven't ridden it since I bought the Giant right after Christmas. Was intending to make it my project bike, but...
... I've realized I'll never actually do anything with the Mamba and might as well move it on to someone who can/will actually use it. Now that I've thought about it, I'd be happy to let it go to someone who wants back in. Even if he has to put on a new fork, that will be his investment - call it a deal because selling it would be a PITA I'm not willing to deal with, and I've more than gotten my money's worth out of it, and why not? If he doesn't want it, eventually I'll end up giving it away to someone.
Everything else works just fine. I've ridden it hard, and it's got about 2,500 miles on it, but it has plenty of miles left, too.
I'm 5'7", 168 lbs. It's a 17.5" frame, G2 geometry; it would probably fit him perfectly. Triple chainring 44/32/22 and a 9 speed 11/34 cassette. Decent tires on it that will last another few hundred miles too. SPD pedals included, too, since I don't need them for something else.
I'm in west Anaheim, near Knott's Berry Farm. If he's interested, shoot me a text at 714 seven four three 6 seven oh eight. I'll come up with a pic or two. Win-win...he gets a bike, I get wall space in the garage
All I ask is that when the time comes, he passes it on.
