I’ve had a few sets, switched from Superstar when they were out of stock of Hope X2s. They are at least as good as Superstar power wise, but they don’t seem very long lasting. However, because conditions vary hugely it’s hard to compare directly.
I just got some uberbike race matrix pads, they’re as strong as my standard xt pads in the dry good conditions but yeah in the wet they’re pretty shitty. Mega loud and not very strong at all so come the grotty weather ill be swapping to something else and keeping race matrix for the drier days.
I really like the race matrix and sintered ones. The race ones are great- very powerful and very long lasting. The sintered ones are the only pads I’ve ever used that stood up to the Strathpuffer. No howling either for me.
Using them here on my rental bikes. The sintered ones seem to last really well and stop just as well as anything else I’ve used. Can’t comment on wet weather performance or noise as we don’t really get any 😆
