Pretty! I remember seeing these on Stephen Roche's bike in the mid-late 80's. Saw some years later on a bike I couldn't afford on a club run. Tragically, the road had just been surface dressed (resurfacing on the cheap). A layer of tar on the tyres picked up the stone chippings which wore through the brake bodies! There were tears that night!
They work incredibly well or not at all. Trouble is there is nothing else between the two extremes! Just look at them then! Please don't let your drool tarnish the finish!
