Well, yes - once I wear the current set. Probably something in 1.75 width, with more city oriented thread; it will be my urban/suburban bike in EU. Time will tell which of Surlys - KM or Troll will be used as city/suburban bike, and which will be spending more time on unpaved trails. But but... the reason for only going to 1x10 on KM is that I can swap tires between KM and Troll... so one set of tires with city rubber, one with dirt / trail type tyres.
I will report on results.. next year :-)
