Do these have the metal spring clips on the back? And are they sintered (meaning, no bedding in required)?
I've used XP12 once and based on the wear I'd say they only last for about 4-5 days. Plus I'm just not sure they're as good (or maybe my braking technique needs lots of improvement).
I'm trying to decide for my next set of track pads, currently considering Pagids, Endless (on the $$$ side) and Cobalt Friction XR1/XR3 (under $500).
