I run 1×9 but I can see the arguments for s/s Quirrel.
a) less to go wrong/break.
b) less maintenance/no cables to stretch.
c) different riding experience (are you a spinner or a grinder?)
would sir like a coffee to finish?
I see the benefit of a 1×9 or a 1×10. You have a chance to get up those hills, but SS, either legs of steel and tungsten or not bothered about pushing up them.
However on a flat city street, then it would be pretty good, or a dirt track, but then it that just saying ss are glorified BMX's. If that is the case, then I see the point, BMX's are great fun, even though I look like a clown riding one with my long legs.
