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

Awesome brakes

I've put it through the wringer

Great modulation with lots of bite when you need it. Not one if the brakes that are either on or off. True mini-codes.

G2 Brake Broke

I've used it several times

Indeed, felt solid, great trail brake. I really appreciated no "wiggle" play in the lever. But, first season, had simple uphill wet root slip and the bike, with zero velocity, laid down. And well, the brake lever snapped, right at the hanger where it attaches to the bars. super simple and snaped straight in two.
