Why We Like The G2 Ultimate Disc Brake

We have a saying around the office that brakes only slow you down, and while we joke that taking everything fast is where it's at, there's something to be said for slowing down and enjoying things around you (or stopping yourself in your tracks before you book it into a bull-moose that's straddling the trail up ahead). SRAM's G2 Ultimate Disc Brakes offer top of the line stopping power for those moments when locking your wheels up matter, whether it's to avoid an encounter with nature's freight train, to rail the perfect line around a steep banked berm, or simply to take in stunning views from the summit when the wildflowers are in full bloom, and the sun is casting just the right alpine glow on everything. SRAM's G2 Ultimate brakes pair technology from the previous Guide Ultimate, like 4-piston caliper, and carbon fiber levers, but with a new S4 caliper, SwingLink lever cam, and carbon blade that keeps things featherweight so you can roll with the stopping power you need, on a brake that's sub 360-grams.


As opposed to the basic Guide R brakes, the G2 utilizes SRAM's Swing Link lever. SwingLink utilizes a specially shaped cam that not only requires less travel and force to produce proportional amounts of pressure, it minimizes the "deadspot" of lever travel. Paired with the new cup-seal timing port closure system, this means that you receive perfect modulation immediately. Once the lever is squeezed, a cup seal swiftly passes this area and closes the port, pressurizing the system and forcing the pads to the rotor. The Ultimate's contact point adjustment feature is found just behind the lever attachment to the master cylinder, making it quick and convenient to dial in the brake's feel.


This pairs up with the new 4-piston S4 caliper. The new S4 caliper design incorporates a redesigned seal as well as aluminum pistons to simplify setup, and improve consistency. The forged aluminum construction means long-term durability and ease of pad removal via the top-loading design. Because some riders like instantaneous power of a short lever throw, and others prefer the feel of a longer throw, the brake levers up front utilize SRAM's Contact Point Adjustment system. This system allows you to pick the position you want your fingers to be in when the brakes engage, enabling you to quickly and easily customize the feel of your brakes without a need for moving the pads.


Another feature tossed in for the G2 Ultimate Disc brake is SRAM’s Bleeding Edge technology, which makes your brake bleeds easier and more effective. In the past, SRAM’s brakes have been notoriously difficult to bleed properly. Bleeding Edge does away with these bleed woes with new bleed porting and a new fluid path that make it easier to push fluid through the caliper. The dedicated bleed adapter for the S4 caliper plugs into the bleed port and seals the system to minimize air contamination and fluid loss. As always, SRAM uses DOT 5.1 fluid to provide heat-management, which dissipates heat and takes almost three times longer to boil than DOT4, allowing for a fade-free performance, even in extreme conditions.


SRAM's G2 Ultimate Disc Brakes come as a Front/Left or Rear/Right lever configuration, with the package-completing Centerline Rotor sold separately. The lever assembly is also Matchmaker X-compatible, meaning you're able to run your various controls off one tidy lever clamp.
