Neither.
CarboTech 1521, accept no substitute.
If you do a search on these pads you'll find MANY very happy users, including myself.
They aren't track pads, but they can handle the canyon runs, and The Dragon, no problem.
The stock wear sensor works with these pads as they use the stock backing plates.
They require no bed-in, just 300 easy in-town miles.
They DO require you to remove your stock rear shim and put it on the rear pads if you don't want that forward/backwards clicking sound. Fronts do no require the shim.
