After spending some quality time refurbing my Record OR brakes the other night I've got to say I think these are a damn sight better than Graftons. I bet most people don't know that these have a grease hole on the base of the arms and you can adjust the bushing slop using the adjustable front cover. Campag quality at it's best.
Actually maybe I spoke too soon...I can't see the grease hole or adjuster on the Icarus but, in that case, I'd say they are equally as good as Graftons!
