Dude, they're only like 12 quid or summat from Brixton Cycles... I was very pleasantly surprised when I didn't have to cough up the normal 20 notes...
edit: I'm talking DA cogs...

Nope then. If it was short term I could lend you one.
What the hell ratio are you going for?

HH jumble. I paid 5coins for an unused DA 14t cog.
It's on the affinity but waiting for the Surly's new chainring to turn up so I can have a sensible gear and a polo gear.

Any offers over £50.00 accepted.

This seems like a good point to ask this. Short of fitting it to the bike, how will I know if I can use a 14th without reducing my chain size. Is there an algorithm I can use or some measurement or other. I can just fit an 18t with about 5mm to spare on campag drops.

Every drop in tooth count shifts the wheel 1/8 of an inch further back.

The chain is 1/2 inch pitch. Add or remove a tooth and you're talking about half the pitch which is 1/4. This is split between above and below the chainstay so divide it in half again.

1/8 pitch FTW.
