Calling Tandem Jeremy to the thr… Oh.
I use the kevlars, not because they’re cheap, they’re just my favourite pads. They’ve been properly tortured- swampy XC racing, fine. Being dragged constantly all the way down the world cup dh route, fine, caliper was burning hot but the brakes never faltered at all- I’d not blame the pads if they’d melted and dribbled out the bottom. Lifespan isn’t amazing but it’s good enough.
I don’t think I’d try them in Avids, too many people have reported problems with the fiddly Avid fitting system (is that just Juicies?). Also people do mention delamination, but tbh that’s just something brake pads do sometimes, I’ve had Shimano OEM pads do it and Disco pads break up a bit (and EBC on the motorbike). Never yet with Superstar but I’m sure it happens.
