Wow can't believe I posted this near 10 years ago.

Went back to find this since don't feel like measuring myself again. Also can't believe the measurements I am seeing.

I got into fixed gear shortly after getting this (above) bike, and have since built 3 bikes. The bike I have been riding the past ~5 years has a 53cm seat tube, and 55.5 top tube. With a 70mm stem and risers. I put a 90mm stem on at times if I know I will be going for a longer ride (10 miles+) as a 70mm stem is a bit crunched (but best for wheelies and bar spins)

Hence my dilemma. Getting older now and when I take my bike out these days its to ride, not really trick and get smoked on the trails by guys simply because they have gears. And after around 30 minutes of riding fixed I am beat. And bored.

Have my eyes dead set on the surly midnight special. I have always liked surly bikes, had a steamroller for a couple years.

Does anyone own one? Its either a 54 or 56. Leaning toward 54. But unfortunately no LBS even up to several hours radius has this bike for test riding. So testing riding one prior wont be possible.

There is an LBS somewhat close by that carries cross checks. They seem to have similar geo in a way so going to test those to get an idea of how a 54 vs 56 surly feels in the drops.

My question to the forum is outside of owning own and being able to call out a 54 or 56 for me based on my above info, are there any other mainstream bikes that have similar geo / sizing I can test to get an idea on sizing for the midnight special?

Thanks!
