after bumping into someone last nite at helios i was thinking of a 17tfreewheel, another question for you, i'm looking into carbon forks & it's been tough finding a rake match for the langster (40mm) so i'm wondering how much can tire size compensate for rake difference, ie: a 20mm tire with a 37mm offset or 25mm tires with a 44mm offset?

I should have freewheels. I don't think the tire is going to change the effective rake all that much, you have to raise the steerer quite a bit to get any kind of noticeable change.

Does the langster have rack or fender mounts?

rackmounts yes, not enough clearance for fenders, although you could get the full wood fenders & cut them, use the hardware to get around the brake mount. no eyelets on the fork though

I think that looks like a pretty cool bike, myself. Too bad about the integrated headset, that would be a deal breaker for me.
