Harris appears to have replacement Kool Stop Modolo pads that don't involve kludging KS-CSRA pads. I don't see them anywhere on Kool Stop's site or another vendor.
For those of us with piles of Modolo/Mavic/Sachs brakes with dried-out or RimShredder "sinterized" pads, these are a great development. Now brakes may actually STOP the bike instead of issuing suggestions.
