Gear ratio effect on stopping/skidding

That has nothing to do with your gearing, you just need to pedal faster.

We're not talking about a superbike here - increasing your chainring size isn't like tuning an engine to make it go faster.
thats the point . . .
dont wanna pedal faster and look like a donut . . .

my mate has a 52/18 and its fine and jus have to get used to it . . . standing up . . .
