How about a picture of your setup? The Riv picture shows oodles of clearance using brakes that aren't IRD.
Your brake pads probably have a set of spacers that have a thick side and a thin side. If the thick side is on the rim side of the setup now, swapping the thin side spacer to the inside will move the pads off the rim, which you'll fix by pulling out some slack in the cable, raising the arch and getting you some clearance. Raising the arch on low profile cantilevers does change the brake geometry, and will reduce your mechanical advantage somewhat. Throwing out that arch wire and replacing it with a separate straddle cable and carrier will enable to keep your straddle height as low as possible while still clearing your rack. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
