Ok, here’s the deal. A couple of months ago I finished my single-speed bike. I started the project just for fun to have a backup from my commuter and to build a bike from the scratch, but in the end the new one is very competent and I’m using it more to exercise than for commute. The thing is that I live in a very flat city, but with good climbs in the surroundings that I would like to, eventually, explore biking… so I was wondering up to what point it’s feasible to climb with no gears? Or, what’s that inflection point where you have to move inevitable to gears? I guess that the answer depends to many factors, including physical resistance, gear, experience, etc… but I just want to hear your experiences regarding climbing using nothing but your SS.

BTW my setup:
Crankset: 170mm 49 tooth
Tires: 700 x 23c
Cog: Shimano 18 Tooth
Steel Frame 52mm
Total weight: 9,3kg

Thanks!!!
