Used Trek 2120
The 2120 was a popular carbon fiber road bike from Trek about 25 years ago.
It featured a mix of aluminum and carbon fiber frame tubes with an aluminum fork. Built up with Campagnolo Veloce parts, the 2120 had a triple chainring front crankset, with great gearing for long tours or hilly road rides.
If you’re somewhere between 5’ and 5’5” tall then you’re in luck. This bike has a 52cm frame and should fit you pretty well.
Only $399.
