I recently purchased a Surly LHT that is 58cm for a cross country tour and commuting. I bought it used for a good price, but unfortunetly, it is far too big. It is the first road bike that I have ever had and ridden, so I didn't really know what would fit me best. The reach on the bike is far too big, (I have heard that surly LHT run a longer top tube) and the top tube comes right up to my crotch when i stand over it.

I am about 5'10", my inseam is 32.75 inches, and I'm am not very flexible. I am going to be buying the 2016 Fuji Touring Bike, and I'm not sure which frame size to get. I think the 56cm would fit me, but I'm not sure if a 54cm would fit me better. I was planning on going to a bike shop and trying a few bikes to try and see, but its hard to tell without riding the actual bike. I need a bike that I can stay on the hoods for pretty much all day if I want. Thoughts?
