Hi

Thanks for clearing that up - and the useful diagram.

I think i've been getting 'QR seat binder bolt' as the name of this part on google - does that ring a bell as it's proper name or can you recommend a popular term if not 'cam lever' which was also used on the links provided here.

One other thing - where previously stated - "You want the 6 mm 30 mm long" - does the 30mm refer to the length of the thread section only ? It seems too small for a length of the bolt itself ?

Thanks again for finalising these details.
