I am currently shopping for a road bike, and have settled on the Trek emonda alr5. I went to the store, and got fitted using their 'machine' and it said 54cm. Online said 56cm, but truth be told perhaps I measured my inseam incorrectly. Anyways I tried an Emonda frame in 54cm and while I could ride it, the trek employee put the seat all the way to the bottom and my arms were fully stretched - it could not go lower, I could ride it but it def felt...stretched. I swapped to a 52 and it felt so much better, so much more natural and I think I will be going with the 52cm. My question is, is it possible that it could be too small? My height is 5'9-5'10 and it seems my height suggest I should be 54-56, and my inseam is 31 from what I measured. It's my first 'proper' bike, so I am a bit nervous.
