Any question answered...

Cycle Surgery in Southwark Bridge had some generic one in stock (Clarks) if you're not too fussed. They'll do the job.

Alternatively sell me your HS66. Pls.

Ha! You really want those brakes don't you. Dont worry, if I ever do sell them you are numbers 1 2 and 3 on the dibs list.

I want to try the red magura pads. Ta though.
