Overview

The Avid Brake Adapter with Stainless Mounting Bolts is an IS (International Standard) bracket set that enables riders to mount SRAM/Avid post-mount disc brake calipers onto frames and forks equipped with International Standard mounting tabs. This is a common need when upgrading brakes or swapping components between bikes with different mounting standards. The adapter is engineered to position the caliper at the correct offset for a 160mm front rotor and a 140mm rear rotor, ensuring proper pad-to-rotor alignment and consistent braking performance.

The included stainless steel mounting bolts are built to handle the demands of cross-country, trail, and mountain riding, resisting corrosion from rain, mud, and trail spray that would degrade standard hardware over time. Installation is straightforward — the brackets bolt directly onto existing IS tabs with no frame modification required. For riders running SRAM or Avid disc brakes on IS-mount bikes, this adapter provides a clean, reliable mounting solution that maintains stable caliper positioning and dependable stopping power across varied terrain.

Pros & Cons

👍 Pros

  • Stainless steel mounting bolts resist corrosion in wet and muddy riding conditions, extending service life.
  • IS-to-post-mount conversion enables use of SRAM/Avid post-mount calipers on frames and forks with International Standard tabs.
  • Supports both 160mm front and 140mm rear rotor configurations, covering common cross-country and trail setups.
  • Simple bolt-on installation requires no special tools or frame modification.

👎 Cons

  • Limited to 160mm front and 140mm rear rotor sizes, so riders wanting larger rotors will need a different adapter.
  • Designed specifically for SRAM/Avid calipers, which may not guarantee fitment with all third-party post-mount brakes.
  • Does not include rotor or caliper — only the adapter brackets and mounting bolts are provided.
  • Plastic adapter components may wear faster than all-metal alternatives under heavy use.
