[QUOTE=Hamatt;1016802]For a start, that chainring/sprocket combo gives you one skid patch if I'm not very much mistaken, so that's the first thing I'd change. Also good luck finding cranks much shorter than 165. I don't think changing the crank length by 5mm or something is going to make much difference to the way the gearing feels. Sorry that's a bit negative.

What do you meanone skid patch?surely no matter what gearing you would wear the same part of the tyre down? or am i just being completely blonde 'ere. So what about a 38t/14t combo? bit easier on the legs uh[/QUOTE]

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.
