Mike,
I tried identifying and sourcing replacement parts at our local bike shops, but that didn’t work out, mostly due to poor inventory.
Here are the parts and sources for the brake upgrade on my wife’s bike; prices and availability seem to vary widely:
Rotors: Hayes V8 203 mm six-bolt from Wheat Ridge Cyclery
Brake pads: Shimano B05S-RX resin / organic from Amazon
“+43” Adapter (post mount) for front caliper: Shimano F203P/P from Amazon
“+43” Adapter (side mount) for rear caliper: Shimano R203P/S from Amazon
I also needed a couple of 6mm ID flat washers to use as spacers between the calipers and adapters to align the caliper and brake pad height with respect to the rotor braking surface area.
These are the parts I used for my wife’s bike, and they’ve so far worked out very well. However, not all bikes use the same specs for each component, so your needs may vary.
HTH,
Jim / crewzer
Caliper and pads are well aligned with “wide” front rotor for maximum pad-to-rotor contact area and optimal braking performance.
