Alright I give in seems too complicated this axial stiffness and come angle business. The closest cone match I got were ones where the ends rubbed against my dust caps ;/ I took the dust caps off so I can ride it for now lol
Thanks for the replies

Does knowing that it's a 10*1mm axle and Shimano hub automatically give me the exact cones I need? I'd prefer to order online than take it to a bike shop
