Let's talk about the JFOYH J02A disc brake pads. First off, the cooling fin design is legit. On long downhill rides, I noticed less brake fade compared to some no-name pads I've tried. The heat dissipation actually works!

Installation was a breeze - popped right into my XT M8000 brakes with zero fuss. The bite is surprisingly good for the price, with a progressive feel that doesn't grab suddenly. Much better than I expected from budget pads.

Now the downside: durability. Like other reviewers mentioned, these won't last through an entire season of aggressive riding. I got about 2 months of weekend warrior use before needing replacement. The resin material wears faster than OEM Shimano pads.

The big question is value. At half the price of genuine Shimano pads, you can afford to replace them more often. They're perfect for: - Winter riding when conditions eat pads - Backup set for long trips - Casual riders who don't need premium longevity

Final verdict? Solid budget option that performs well... just don't expect miracles in the longevity department!
