I have 26x2.1 front and 26x1.9 back on my MTB. The grip is good, but it takes alot of effort cycling so now I'm looking into replacing the tyres to other which has low rolling resistance and puncture resistant so it's going to go quicker, but more energyefficent (so I won't come exhausted to classes).
I'm not sure about the wheels, how low I can go and I can't buy new wheels too. The wheels is like 1,9 mm width |---| like the --- is 1,9 mm. I want as small tyres as possible. Any ideas how far I can go?
I'm not going offroad, maybe a shortcut on grass, gravel, but never in the woods. But it highly likely I'll ride on wet surface. And when it's snow, I'll switch back.
