So do these various new "wonder pads" work well on steel rims? "Old Schwinn 3spd" and "60's vintage Raleigh" sound like steel rims to me, and BITD, Mathauser pads had a rep for being SUPER grabby (as in dangerously so) on steel.
Oh, and the comment about Campy brakes not needing KS or other aftermarket brake shoes made me laugh. My first set of Campy NR brakes stand out as the absolute effing WORST brakes I've ever used until I switched out the Campy pads for Mathausers. No stopping power a tall. Modulation? Sorry, gotta have stopping power for that. And even with the new shoes, they were marginal compared to most other brakes I've used. Pretty, tho'.
