aluminum road bike set up for commuting - hopefully the pics say most of the story. Front chain rings are 46/36; rear is a 30 tooth cassette (I think - I would have to verify). Tires are 25C. Shifters are Tiagra 9 speed. A lot of improvements from original build: i.e. carbon seat post, carbon fork. Rear rack, cross top brake handles, fenders. Fits 5'5" to 5'7" (i'm 5' 8 1/2/"). Pedals are SPD You're welcome to go for a test ride, but you have to put $600 in my hand first as insurance against theft...
