Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

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.
