I want to buy a Surly Long Haul Trucker frame and build it up, but I’m not certain what the correct frame size for me is. I have always been a mtn biker and have no experience with road frame sizing. My mtn bike (Yeti 575) is a Med (18.5").
I went to my LBS and according to the Fitstik I need a 56 cm road frame. I also tried measuring my inseam according to Colorado Cyclist's instructions and I got 32 inches (I am 5'8" tall). Based on my 32" inseam using CO Cyclist’s calculations comes out to a 54 cm frame. But after getting on 56 cm bikes at the bike shop I believe 56 is the right size, however Surly's touring frame sizing is quite different from the geometry of the road specific bikes I was looking at.
My LBS put me on a 19" Trek 520 (the only touring bike they had), which has a 21.5" effective top tube length and a 28.6" stand over height. The Trek frame size felt pretty good, though they said I looked a little stretched out when riding with my hands on the brake hoods.
Given that the 19” Trek frame is probably the right size for me, I assume I need a Long Haul Trucker with a top tube length around 21.5", which would put me on a 52 or 54cm LHT. The 52 and 54 cm LHT frames have 21.3” and 21.9” top tubes respectively.
Any advice on picking the right frame size for me would me much appreciated.
