i shouldnt worry about it mate, unless you are trying to do a 'moto guzzi' with your nee on the ground. i ran a conversion on a low end peugeot for ages with 175's my pedals never clipped the ground once even on fast corners. get some 165's if your feeling angsty about it tho because you want to enjoy your riding and not be worrying about stacking it!
