Lightweight Trek road bike with carbon fiber frame, hydraulic disc brakes, and Shimano 105 2 x 11-speed drivetrain (50/34 crankset). Bike is in great condition and fresh off a 100-hour tune-up and drivetrain cleaning from Cahaba Cycles. This bike rides like a dream and climbs like a mountain goat, but I'm selling it to move to a 58 cm frame, which is a little better fit for my height and build.
