Once when I was a better, less broken biker I caught a couple of guys on MX motorcycles on a rocky, nasty downhill. I have rarely enjoyed embarrassing someone so much as when I asked for (and got!) the trail from them.
I have trashed to many of my moving parts, too many times, to smoke the MX'ers any more, though. That is a beautiful bike, and I know what you're saying - that's the one that I'll build up some day.
Dean TI post, Marinovater brakes, Paul's love levers, Ringle cranks (maybe) - Nuke or White hubs, 28/32, MA-217's, and I have some ultralight Conti Cross-country tires salted away. And the mission control bars, of course. da bomb.
