the amount of skid patches you get completely depends on the gear ratio.
you can check 2 ways either by using the simplification rule - you treat the ratio as a fraction eg 42/14 and simplify until you can't any more. so 42/14 becomes 3/1 meaning one skid patch, 46/20 becomes 23/10 = 10 skid patches and so on.

or you can just use this thing which tells you your gear inches as well

38/14 gets you 7 skid patches and is about 71 gear inches which is a fair bit softer but by no means a spinny ratio.

aha it's all becoming clear,well kinda. Just haven't a clue what gearing really,i don't want to change hub as that is new so the only thing i can change is the chain ring,i'm happy with the gearing i already have......just could do with shorter crank if i can.

But thanks v much for advice guys appreciate it...
