ive got some, I swapped from the standard hs1’s on the x0 trail brakes
they have defo cured the turkey gobble/vibration in the WET! so that’s a defo way forward
they are completely silent in the dry as were the hs1’s, but they still squeal in the wet (with my uberracebike pads matrix mix anyways), but so does everyone else I ride with
ive got some new sram pads to put in so im gonna try them fresh with a new set of pads (as the old rotors, will have had an effect on current pads)
the main thing is they have defo cured that pretty horrid feeling braking in the wet
