Hi All, Can anyone confirm the size for the replacement Cannondale cantilever brake boss size please? Does anyone have a front & rear set they'd sell, or know of anywhere that sells them?

appreciate any info

Not sure if they are in stock though.

Got mine from qwerty, but they are out.
They are a strange imperial thread that no one else uses. I considered going down the helicoil route and just fitting standard 8mm.

The size you need is imperial: 5/16-20. Do NOT try to screw in the M8 ones that are very close in size but you'll ruin the fork or frame (almost happened to me).
If you want to spring the big bucks for a pair of titanium ones there's this e-bay seller that has those:

Re:

I don't think the ti ones are that expensive! Surely it's better than having a useless frame and fork?

Sorry for the necro-post, but if anyone reading this from a casual web search looking for the correct brake boss size for a vintage Cannondale, this is incorrect. They are 5/16-18. You'll be looking for a very long time for a 20 tpi brake boss because they don't exist.
