Why We Like The SRAM G2 Ultimate Disc Brake

SRAM's G2 Ultimate Disc Brakes offer top-of-the-line stopping power suited for aggressive trail riding, when stopping power is key but weight is still a concern. The G2 Ultimate brakes pair technology from the previous Guide Ultimate, like 4-piston caliper and carbon fiber levers, but in an even lighter package. The contact point adjustment dial lets us fine-tune the bite point of the lever pull, and reach adjustment dials let us adjust the lever blade positioning for comfort.


  • Beefy but light brake for slowing things down on the dirt
  • 4-piston S4 caliper for powerful stopping with every squeeze
  • SwingLink lever cam and cup-seal timing port for improved modulation
  • Carbon lever blade and titanium lever hardware shave weight
  • Stainless steel heat sink reduces braking temperature
  • Revised bleeding port for easier, more reliable bleeding
  • Matchmaker X-compatible streamlines bar set-up
