Avid Shorty 4 Carbon Brake Pads I have Avid Shorty 4 brakes on a cross bike. I would like to use zipp 303 carbon wheels, but I am not sure about brake pads. The brake pads on there now are a combined cartridge and pad set. You cannot replace the pads. Any recommendations on pad holders and brake pads for carbon wheels that would fit well on Avid Shorty 4 brakes?

Thanks-
Assuming your current pads are V-brake style, these pads should work well: http://www.swissstop.com/rimbrakes/rxplus/yellowking/

As for the pad holders, it's not easy to find them sold without pads, nor with carbon pads.  That's too bad, but you can buy these anyway and use the pads on another bike: http://www.koolstop.com/english/v_type2holder.html
