Hi everyone, I just finished a Trek Calypso what a great bike and a very easy build. The frame is longer than a Schwinn cruiser, it's very comfortable and smooth. I added the prewar handle bars and`my good looking and great sounding exhaust. I tried something new with the exhaust most of it is silicone tubing, so far so good, I've put about 40 miles on it and it hasn't burst in to flames yet. I'll let you all know if it fails otherwise a very easy way to run your exhaust/ if anybody has built a Trek Calypso please post some pictures I would love to see them Please ride safe.
