🔥 Compound Type: Semi-Metallic (Standard Range)
The Semi-Metallic Compound offers quiet, consistent braking and excellent modulation. It’s ideal for Road, Gravel, and Cyclocross riders who value control, minimal noise, and rotor-friendly braking under mixed conditions.
Gorilla Brakes is trusted by riders worldwide, with over 13,000 verified positive feedback ratings.
We also work closely with race teams and sponsored riders to validate performance in real-world conditions.
The Stealth compound is a welcome variant of a more regular sintered compound. Same power with the added bonus on low noise, especially in wet conditions.
The bedding process was surprisingly quick as well.
I had a chance to test these pads on local trails without issues. No signs of fading after long downhill braking
