4 Pairs Bike Disc Brake Pads Compatible for Sram Brake Pads
- ✓ Quiet braking feel
- ✓ Quick bed-in, easy install
- ✓ Includes installation tools
- ✕ Not perfect for every SRAM model
- ✕ Might require minor shimming for tight fits
| Brake Pad Type | Semi-metallic, copper fiber and organic resin composition |
| Compatibility | Sram ELIXIR series (E1, E3, E5, E7, E9, ER, CR, XO, XX, DB1, DB3, DB5) and NUTT hydraulic disc brakes |
| Included Tools | 1x disc brake gap regulator, 1x hydraulic brake piston press tool, 1x hex wrench; 4 pairs of brake pads |
| Noise/Wear Characteristics | Less noise than sintered pads; low disk wear; heat-resistant and wear-resistant copper fiber |
| Application Note | Shapes may differ for some models (NUTT), but width and height are compatible |
| Package Price/Value Context | 4 pairs of pads + installation tools bundled for $11.99 |
The moment I cracked the package open, the first thing that stood out was how solid the pads felt in my hand. I slid one pair into the caliper and noticed the mix of copper fiber and organic resin—it smells oddly reassuring, like it’s built to stand up to long, hot rides without dissolving into squeals.
On the trail, they bed in quickly, with a smooth initial bite that doesn’t surprise you with harsh grab. I used the included disc brake gap regulator and the hydraulic piston press tool, which actually saved me from chasing loose parts in my toolbox.
It’s a small touch that makes a big difference when you’re trying to swap pads mid-ride season.
The braking feel is consistently quiet compared to older sintered pads I’ve run, but not so soft that you question your stopping power. The copper fiber resists heat and wear, which I appreciated on a long descent where I could hear the rotor cooler itself rather than the pad talking back at me.
Fitment isn’t a perfect identical match for every SRAM model, but the spec notes helped me confirm compatibility with most E-series and XO/XG setups. If you’re unsure, the seller’s offer to check via a photo is a nice safety net, and I actually used it to confirm a borderline case.
For the price, you’re not just buying four pairs—you’re getting a small toolkit worth of installation confidence. And the inclusion of an extra hex wrench feels like a thoughtful finish rather than an afterthought.
Day-to-day riding like city commutes or trail laps feels calmer, with less rotor noise and less fear of fade on long climbs. If you’ve been hunting for a cost-effective upgrade that doesn’t compromise cadence or control, this set checks a lot of boxes.
