So I ordered a small red and white sunday factory frameset from them around 4 months ago. I waited 2 months and then decide to call and see whats up, they said that iron horse didnt make a ton of red and white frames and that if I wanted my bike now I would have to get green. I had just had surgery so I figured Id wait. About a month and a half later I called again. They said that they couldnt get any red and white ones and that I would have to take the green, at this point I didnt care so I said ok, and go-ride said that iron horse would ship the bike to them and then they would ship it to me. Another week later and I called to see what was up and they said that Ironhorse sent a seventeen inch frame in a sixteen inch box and the guy at go-ride said he would get it all figured out. I wait another month and the other day I get a phone call back saying that the people who make ironhorses frames didnt make enough sixteens and ironhorse has to make them from scratch and that would be another month. At this point I NEED a bike because I am just healing from surgery, so I am most likely going to take the medium. I am 5 foot 6 and im not so sure about the size. Could anyone tell me how they measure theyre frames and if you think I can get away with the medium. thanks and has anyone had any problems like this with Go-Ride?
