Hi all, I usually partake in the clydesdale forum but I thought this would be more appropriate in here. One of my friends recently moved and before doing so, he sold me his Trek Valencia in size Medium with 20" frame. I'm 6'3" and my inseam is about 33-34". The frame sizes that I usually get are 22-22.5" (mountain bikes) and 60-63cm (road bike). I currently have the seat up about 6". Everything feels great and I it feels bigger than a previous bike I had which was a KHS Urban X size XXL with a 22" frame but with 26" wheels. So, I mean, this shouldn't be a big deal because its a wonderful bike. If it fits, it fits, right?
