although i've been skating for over 20 years, my go to wheels have always been spitfires or bones in size 52mm, the harder the better. now that i think about it, i realise that i don't really know how different parameters affect the performance of the wheels. I know about size and hardness and their effects, of course. but i'm wondering in particular: what is the advantage/disadvantage of conical shapes? what is the advantage/disadvantage of a wider/narrower wheel tread?
Thank you
