Wheeler 9800. Most likely Tange Prestige tubing.
The only high end parts on it yet are the XTR derailleur/shifter, and the titanium stem. But I plan on upgrading the rest piece by piece, whenever I can find something nice on the cheap. The goal is to get it under 10 kg.
I have two bikes that I consider 'upscale' from the other--a 2011 Marin Belvedere 24-speed commuter in gunmetal and my vintage 1981 Trek 412 roadie in excellent shape. Different eras...different riding experiences. (Photos to follow.)
