I have seen this quoted as 11mm x 1 for Italian hubs, but on taking the studs out of genuine SX200 front hub in preparation for fitting SIP Rims, I reckon that they are 10mm x 1.
Anyone have the definative answer?
(I know if the SIP studs fit who cares, but I am having to drill one stud out (there's always one that won't come out

). I only have normal right hand thread taps so I want to get a left hand tap incase I have to clean up the thread).
