ok.. im not one to buy into hype... and when i was in need of brake pads ( my stock ones were causing GALLING on my wheels) i said why not and lets see what these brake pads are about... i went with KOOLSTOP (full salmon) and (HALF salmon/half black) ... ive been on the half and halfs and after riding many miles you can really feel the difference ... i found them quieter on my rims... and very very solid for braking....
