Carlo and the guys at Proper have delivered the goods again with this new brake of theirs. Heres what they had to say:

This is the new brake from Proper. It comes with a CNCed hanger and all the hardwear including the clear pads (Baradine/Plasmatic style) that we recommend for use with Proper wheels and rims (or any other coloured rim brand). Available now in the UK in black, white, gold, purple, blue, red, and magnatitanium grey.

Splendid!
