Are these still available? I was searching online for "m10 titanium brake boss" for an early Kona HeiHei and your thread here was on the first page results along with one from Pip.
I am looking for m10x1.00 mm pitch. These are 1.00 mm or 1.25 mm? A bit hard to tell from the picture. Also the overall length of the threaded portion up to the machined face that 'bottoms out' on the frame looks deceaving too. The ones I have on hand measure 8 mm along the threads to that machined face.
Cheers
