what is 4yr Trek Fuel 90 worth?
This bike looks in really good shape. It has all the stock components that came with the bike new (deore XT were some of them). I don't really know much about mountain biking so I'm not sure what to look for. I'm 5'11.5 and have a 31 1/4" inseam. Measurements taken in bare feet. I had one bike shop fit me on a fuel 90 and tell me I needed a 17.5 and a different shop fitted me on a fuel 90 and said I needed the 19.5 bike. How can I tell what size I need? Any advice would be greatly appreciated. Thanks in advance for the help.
