what kind of rear brake is that?
Hi Marcel- this is a home-machined brake. I guess a paul crosstop would have been the obvious choice to match the lever, but it didn't seem right. Too round. The detail on the rear end of the bike features box sections with drilled holes and pockets in the alloy, and I wanted to keep this style, - similar to the style of the early Ringlé skewers. As the machine was also a bit of a Ringlé tribute bike, I wanted the style to match.
They are very very sharp brakes. One day I'll get off my butt and maybe offer them for production, together with the special pad-holders. Spring tension adjustment is very easy, and the diameters of the adjusters even match the contours of the spanner perfectly when tuning them.
