Shermer, I have had a 1×1 for the last five years and it is great to ride. To be honest I find Surly’s a bit lonbg in the top tube, I have a 20″ 1×1 and a 58cm Cross Check and I wish I had an 18″ and 56cm, respectivly, but I manage with shorter stems and a good choice of bar.
I mix it up, running it rigid with 2.4 tyres and with a Reba 100mm Dual air and a set of 2.25s. A very capable bike, heavy, but then its a Surly and it will last for ever. Its a bike that just wants to be ridden anywhere and everywhere. I cannot recommend them highly enough, but it is not for the racer in you, more the long day in day out rides and the chance to switch to rack carrying urban cruiser.
