Semi metallic and resin compounds both offer useful choices for braking feel. Start with your riding conditions, bicycle type and the specific Gorilla Brakes range.
How the materials and compounds compare
Semi metallic
Semi metallic materials combine metallic particles with a resin based friction mixture, giving a balance of bite, control and wear resistance.
Our Semi metallic Performance compound is for everyday conventional bicycles. Enduro Pro Semi Metallic Blue is the separate Enduro Pro option for more demanding riding and electric bikes.
Resin and organic
Resin based pads combine a binder with fibres and other friction ingredients. The formulation determines braking feel, wear resistance and temperature response.
Enduro Pro Resin Black combines smooth modulation and a quieter feel with the Enduro Pro focus on pad life. Factory Racing Organic is a separate compound for quiet braking and feel, particularly in dry road, gravel and cross country riding.
Choose the braking character for your regular routes
Semi metallic is a useful starting point for conventional commuting, road, gravel and lighter trails. Resin options are worth comparing when smooth modulation and a quieter braking character are your priorities.
Enduro Pro Resin Black combines that feel with the Enduro Pro focus on pad life. Factory Racing Organic is another resin based option, suited to quiet braking and responsive dry weather feel. For touring, electric bikes, cargo bikes and longer descents, consider the separately developed Enduro Pro Semi Metallic Blue.
Check suitability before changing compounds
Match your pad shape and rotor specification first. Our Performance range is for conventional bicycles and is not rated for electric bikes. For demanding electric bikes, heavy cargo bikes and long alpine descents, start with Enduro Pro Ultimate Orange or Enduro Pro Semi Metallic Blue in an approved fitment.
Use the full compound comparison for riding recommendations and measured braking power in watts. Follow the bedding in instructions for the pad and brake combination you choose.
Questions riders ask
Does semi metallic also contain resin?
Semi metallic compounds commonly use a resin binder alongside metallic and other friction ingredients. The names describe broad material families rather than identical recipes.
Which resin compound should I compare for trail, road and gravel?
Enduro Pro Resin Black offers smooth modulation and a quieter feel with the Enduro Pro focus on pad life. Factory Racing Organic is a separate option for quiet braking and responsive dry weather feel.
Does more initial bite mean better modulation?
They describe different aspects of braking. Initial bite is the response at first application; modulation is how progressively you control braking force. Compare the specific compound and complete setup.
Can I choose by the material name alone?
Choose the named product, approved fitment and intended use. Performance Semi metallic and Enduro Pro Semi Metallic Blue have different recommendations even though both names include semi metallic.
