Just installed these bad boys on my gravel bike after my OEM pads started fading on steep descents. The difference? Night and day.

PROS: The aluminum cooling fins actually work - did a 2,000ft descent last weekend with zero brake fade. The magnetic attachment is genius; swapped pads trailside in under 3 minutes. Wet weather performance is insane - rode through a thunderstorm and they bit harder than my old resin pads in dry conditions.

CONS: The break-in period is real. First 20 miles felt sketchy until the transfer layer formed. They're definitely louder than organic pads when wet (makes a metallic 'zing' sound), but that's the tradeoff for this level of stopping power.

BEST FOR: Riders who prioritize consistent braking over absolute silence. I've used these for everything from loaded bikepacking to crit racing - they deliver Shimano's legendary modulation with the durability of metallic compound. Pro tip: Keep isopropyl alcohol handy to decontaminate the pads after muddy rides.
