Have a Trek Pilot 5.0 endurance road bike, size 52cm (small) should fit riders up to 5'-6" give or take couple inches. This is a great looking bike, the red really pops in the daylight, hard to tell from pics since I took when cloudy but trust me it looks great. It also has really good components. It's an older model, around 2008, but it's in great shape. This is a fast bike with an OCLV 120 carbon frame and fork. Nice fast bike with mid-level components without breaking the bank. The drivetrain is a 30-speed (3x10) Shimano Ultegra/105, brakes are Cane Creek SCR-3L caliper rim brakes, wheels are Bontrager Race 700c paired with Continental Gatorskin 25mm tires. Weighs in at around 17lbs w/o pedals. Bike has been cleaned up, tuned up, it's ready to ride. Text number listed, thanks.
