1) I measure 120-92-103. The brakes appear to be 110's (or thereabouts). There is a DIN scale window missing on one toe piece...
M51 TwinCam 4-12 DIN. Obviously the toe is adjustable, but as is I can click in with a 317mm boot.
Yours if you want em. PM if you want me to do any other testing first.
2) For coining "Ludditious". ;-)
