Compatible with Sram HRD(Apex,Rival,Force & Red) and Level brakes. High Quality organic pads with kevlar. I use these pads on one of my own bikes & they are powerful, quiet, long lasting and at least as good as the genuine Sram organic pads costing 3 times as much. Please check my feedback as I have now sold over 200 pairs of these pads all with positive reviews. Cheapest pads of this type for sale in Australia with fast local shipping from Sydney(not Sydney after drop shipping from China like most of the cheap Au sellers!). This listing is for one pair of pads. Free standard postage with discount if you buy more than 1 pair or express post for $12.20
