has anyone tried the miche cog/carrier system? if so, what are you thoughts on this: im in search for a cheap, safe, serviceable method of converting rear wheels to fixed without buying a track hub. if the diameter of the carrier was smaller than the flange of the hub, i would think you could weld / jb weld the carrier to the hub allowing swapping of cogs, spoke maintenance, should be safer than bb lockring and would be cheaper & less labor intensive than a hub swap. any thoughts?
