A bike I had acquired used had old Jagwire brake pads. Yet, the brake pads were still functioning as if they were new. I bought these brake pads for another bike. These pads are very smooth and sure, even when braking from a high speed going downhill. Note, there is a direction of travel and a left or right side when installing these brake pads, as marked on the outside (post side) of the brake pad. The yellow pads complement the color scheme of my bike as well.
