thanks !, I took into the shop today as I was buying new tires , they are very cool people, gave me the same advice, but I was told formula hubs dont really need the cone nut to hold the bearing ? as these are cartridge bearings i guess. but the same adjustment of bearing locknut and cone nut is required, kinda confusing, but i will figure it out. still new to fixed gear stuff, should be simpler you would think.
any way, they didnt have the size of cone wrenches i need, so still need those.
