Used Trek 2100
The Trek 2100zx was a popular and affordable road racing bike from Trek about 15 years ago.
The 2100 featured a mix of aluminum and carbon fiber frame tubes along with an aluminum fork. This model was built up with Shimano 105 10-speed parts with a Truvativ triple chainring front crankset. The light-weight build coupled with great wide-range gearing made it a good pick for long tours or hilly road rides.
We have updated the design a bit by making it a flat-handlebar bike, with Shimano Tiagra 3 x 10 shifters and flat-bar brake levers.
If you’re somewhere between 5’8” and 6’ tall then you’re in luck. This bike has a large 56cm frame and should fit you pretty well.
Only $449 and it comes with a 1-year warranty.
