Looking to sell our Trek 7.2 fx Hybrid Men's Bike. Seat tube measures 20". My roommate recently had to move state and wasn't able to take his bike with him! I am trying to help him out by selling to a new owner! Great bike for around the town as well as out on the trails. Great reviews online! He only had it for a few years and rode it mainly around town. Shoot me an email if you are interested and I can send pictures!
