Always a tiny bit wary of recommending these in case someone dies, but, I use these, the red ones

Had them in all my bikes for a couple of years now, from dh bike to fatbike, they work great- wee bit noisy but super consistent, last well, and of course at £2.50 a pair you’re never tempted to piss around getting more mileage out of them or cleaning them or whatever. Had my doubts obviously but after a couple of weeks in france including the mega, some UK uplift weeks, and lots of orrible scottish #enduro all condtions rides, I’m totally happy with them. (in various old Formula The Ones). I wouldn’t use pads just because they’re cheap but cheap and good suits me.
People have varying opinions but I found Racematrixes really good for a few test rides here at home, then I went out to the alps and they absolutely shit the bed, outright dangerous- I assume it was just heat, but I’ve had the same brakes hotter without a peep. Definitely wasn’t the brakes, I binned the pads after half a day and just threw in whatever it was I had in my spares and they were fine.
