Pads: Coustsinks in Pimp backings Time used: 4 months Rim: Try-all Grind: yes, once every 3 months, beginning of new pads. Fairly rough. Tar: F*ck no. Previous pads: Plazmatic crms, koxx bloxx red brown green yellow, koolstops, zoo!, heatsink blues reds honigs. Prefered brake: Lock, bite, working under anything in anything. Review Amazing. Working in wet, damp, soaking conditions. Makes Try-alls slip. Super solid due to the CnC'd backings, which at first i thought was a waste of money, but it is an ace investment for a solid brake and cheaper replacement pads. You don't need tar at all with these, so you might as well use it on your roofing. You don't even need a regular grind, jus when it smoothens out. After a while of use(about 1 monthish) the super bite starts to die down. But don't worry, you won't stop noticing it! Try not to drag your brakes down big hills like Shipley Glen, because your pads wear quickly www.heatsinkbikes.com to place your order
