So... here is my only geared bike. Originally a 2001 Trek 5200 (USPS model) I bought used for parts (the frame and fork both had cracks) to put on a 2012 Motobecane Vent Noir frame and fork from Bike Island.
Everything having to do with making the bike go or stop is Shimano Ultegra except for the pedals, which are Look KEO Classics. The wheels are Mavic Ksyriums, and the bars are Bontrager RaceXLite Blades. The saddle and seatpost were not original on the 5200 when I bought it, they're both Bontrager with the seatpost being, I think, RaceXLite (or Race Lite) carbon.
It's one hell of a fun bike to ride.
