I am also looking for U-brake studs, M10 x 1.25 thread for a Sandvik titanium frame as well. Mine was produced for a local company called Asama. Hesitant to order the studs from brake-stuff.de since they look so different. https://brake-stuff.de/en/canti-studs/27/canti-studs/brake-mounts-for-u-brakes-in-size-m10x1.25. I have a friend with the same frame but complete, annoyed that mine were missing. trying to keep this thread alive
