Where the boss screws into the braze-on. I now know they are *not* the same size as the Hope hose guides ๐
They are 10mm, but does anyone know the TPI? I was thinking to make up my own.

Just checked my Instigator and it's 10x1. All Surly frames probably use the same bosses. If you still have the boss, and it's about that size, you could just try threading it into a derailer hanger to confirm. Or thread a derailer into the boss mount. Or, yknow, measure the pitch with a ruler.

Ta muchly for both responses. I shall be heading down the local hardware shop and thence to a nice man with a lathe that understands such matters.
