After lots of reading and thinking and test riding, I have decided to go ahead and start my single-speed build. Bike purpose: hilly urban errand-running, friend-visiting, casual riding. I want to get a steel frame with semi-horizontal drop-outs, so I have option to go geared in the future.
Decision: Surly Cross-Check or Salsa Casseroll. The biggest functional difference between the two frames looks like the different brake requirement.
I am leaning towards the Surly [color, durability, fork design], but I read about problems adjusting cantis. Is this brake requirement a good reason to steer clear of this frame, and go with the Salsa? Or, am I worrying about nothing?
Thanks for your insights and advice!
