XT +1 – I’ve not used them *that* much but completely fit and forget so far with no maint for almost 2 years.
also used clarks pads with them on a 4 day trip round torridon ( that place eats pads for breakfast) and didn’t even use a full set where others wore out 2+ sets.
I’d love to attribute that to my lack of need for brakes or setup, but i fundamentally believe the pads retract further or have more clearance because i just didn’t use anywhere near the pad material that everyone else riding the same trail did.
they are reliable and powerful. doub’t i’d go back to Avids having had these
