I have quite a bit of experience with cycling in general mountain bikes especially. This bike got me stumped, it has a Titan racing stem, vintage Easton peregrine carbon str8 bars, Easton answer Manitou front shocks, headlock headset, deore LX groupset, and a seat post that has an "A" and a star and USA. The frame itself has a couple numbers under the bottom bracket but I haven't been able to come up with anything. Also on the under side of the down tube it has what appears to be an "easton" "E" stamped. Thanks for any insight!
