has anyone ever tried putting a spacer between the cog and the hub on a formula hub? i want to use a 1mm spacer so my chainline is dead on and i was wondering if there is enough threading on the formula hub. if it helps any i will be using an EAI cog and durace lockring. i'm just trying to figure out a way to get around buying a Sugino 75 bottom bracket till i have the money.
