"Bontrager Speed Limit Brakeset" ... Any thoughts?

Wondering if anyone has had any good or bad experience with these?

Find it a little wierd that I have yet to find them in any of the "usual suspect" e-tailors (Wiggle; Ribble; CRC etc.), but I have found two places offering them below the standard £90:-

Has anyone used either of these two shops?
