The CLBs in question are not the lightest nor last of the superlight brakesets they produced. The SpaceLine was the last/ultimate, and they also were first produced in the Ti shaded color of Al and then in white at the end of the run (I'd say mid to late 80s from my reading of Le Cycle)-- any have any leads on those white ones???. The cable/housings were stretch-prone, otherwise the brakes themselves were just about the same as sidepulls of the day, which is to say that when I mount my vintage Vitus with SpaceLines, I have to factor in the less than adequate by today's standards braking.

I don't believe these are ti. Logically there would be no reason to make them out of titanium. Titanium is heavier than aluminum and CLB makes (made?) aluminum brakes just like everyone else did beginning in the mid-1930s.
