Gear ratio effect on stopping/skidding

Be careful with that, my flatmate's just gone from 44/17 to 46/17... I think it's turned him mental, he pulled the windscreen wipers off a car that cut him up yesterday... He wants more speed too so getting a 48 on the front now... There will be carnage...

right now i got a 47/18 and its too slow for me . . . so im lookin at 52/18 . . .
cant be having foldup bikes passing me . . .
