I got this old Trek 720 Multitrack free from a neighbor down the street. I rebuilt this bike into a cool little hybrid-type bike just as a fun project. I added tires and tubes (it didn’t have any), re-trued the wheels (they were bad!), swapped out the cruiser handlebar with a straight bar, put on a new chain and built a new front brake cable for it. I added brakes, the rack, the fenders, a seatpost and seat (it didn’t have either of those), stuck on some bottle holders and reflectors, and gave it some brake shoes all around. I’d still like to get some new pedals and seat, but I think it’s coming along! :)
