This bike gets pretty good reviews. It's supposed to be very aero as well. An interesting note about this frame is that it has been sold under several different companies over the years. Mongoose had it for a while, as did Martec and maybe even Epx (not sure about this last one, though). Right now, you can find the bp Stealth frame under the old Martec brand on
www.chucksbikes.com. It sells for about $385. The only thing about the Martec-branded frame is the color -- it's a rather bright yellow. If the yellow doesn't bother you (and if Chuck has your size), you can get the frame for about half the price of the black bp Stealth frame that is currently available. And for the record, I'm not affiliated with Chuck's Bikes, and have never even done business with him. But plenty on this forum have, and he's got a good reputation for customer service, and if he has what you're looking for, his prices rock.
