These brake pads are perfect for keeping your mountain bike stopping smoothly and safely! The semi-metallic compound handles high temperatures like a champ without fading, giving you consistent braking power even on long downhill runs. Each pad measures about 28.5mm long x 22.5mm wide x 4mm thick - just check your current pads match these dimensions before ordering. The resin semi-metal material is wear-resistant and dissipates heat efficiently, so you get longer life between replacements. Installation is super straightforward - no special tools needed, just pop out the old pads and slide these in. You get 5 complete pairs in the package, which is awesome because brake pads wear out at different rates and now you'll have spares ready to go. Compatible with many popular brake systems including JAK-5, BBB7, TONGLI, and others - as long as the dimensions match, you're good to go. The strong braking force gives you confidence on technical trails, and they operate quietly without annoying squealing. Perfect for riders who want reliable performance without breaking the bank. Keep a couple pairs in your trail repair kit - you'll be glad you did when you need a quick trailside fix!
