    spacer and cog question

    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.

    What did you end up doing? I'm having the same problem with my setup. I still need to find a spacer to fit between my hub/cog.

    i wouldn't put the spacer on. 1mm off chainline shouldn't hurt. i wish i could find the thread, but there's something on here about a mechanic who's worked at the olympics saying, what...within 4mm is fine.

    i wouldn't go that far, but 1mm shouldn't hurt you, at least not as far as i know.

    i ended up buying a sugino 75 bottom bracket spindle for $32 and just bought some used but in good condition shimano cups. i spent $40 all together rather than spending $80 something for the whole sugino 75 bottom bracket.
