Surly Steamroller

I'm just interested. Why have you chosen a steamroller? If you've not ridden one yet, pay the money to get somewhere to try one. I've also ridden a Charge for a bit, and the medium felt massive to me, so a 53cm Creamroller is my choice of commuter. But i had to ride it first to make sure.

The Plug is a big bike, I have both an M and an L. I hop between two locations during the week, with a bike in each, and am considering selling the M (I find it too small) and getting a Steamroller for the sake of something different.

I don't know where you live, but my shop stock the steam roller. I ride a 53, I'm 5'10", but I'm also weir proportion (aka female).
Come by Brixton cycles if you have the chance, we seem to be Surly central at the moment so there will be a few sizes to stand over.

I live in Ireland, so no chance of that ;)
