🔥 Why Choose Sintered?

Our Standard Sintered compound is the workhorse of the Gorilla range. Unlike organic pads that can wear down quickly in the rain, metallic sintered pads maintain their friction profile even when saturated with water or mud.

  • All-Weather Reliability: Predictable lever feel in wet or dry conditions.
  • Heat Resistant: Fused metallic particles prevent "brake fade" on long descents.
  • High Durability: Lasts significantly longer than resin/organic alternatives.
