I'm 5'-6.5" with a long torso relative to inseam and fit best on a M. I know someone about my height riding an S but an S was just too small for my body type. ML sounds like it could fit you, but I'd definitely try different sizes if you can. Fit will depend on your body type. I was able to have a bike fitter show me what was going on while I pedaled on a trainer in front of mirrors. Good luck!Lamdog said:ProudDaddy, what size Siena do you have? I guess how tall are you also? Just wondering how you fit on the bike. I'm 5'-9.5" and seem to fit the ML well ... guy at the shop said I'd probably fit a M or ML.
I rented one in Colorado with a Compact crankset.Lamdog said:Wanted to know some impressions and review from others before diving in ... thanks all!
