NEW SRAM G2 Ultimate and RSC Brakes [Video]

SRAM G2 Ultimate and RSC Brakes

The evolution of the SRAM brake line continues with the introduction of the new G2 Ultimate and RSC brakes. Moving into the second generation of Guide, which is where the G2 moniker comes from, the G2 brake is completely redesigned, increasing power and lever feel. It's no secret there were previous issues with older SRAM/Avid brakes, but those should have been long forgotten with the introduction of the Guide, Level, and Code brakes. A generation of riders were converted after SRAM proved the power and reliability were there to stay. Guide brakes have been the staple for the SRAM brake line for a few years now, going on bikes from light trail rigs to even DH bikes for a while. The Levels have been reserved for XC extremists and Code brakes eventually found their home on DH bikes and some big, aggressive trail riders’ bikes. G2 builds on the success of the Guides, which now in its second generation offers some amazing improvements.

The New G2 brake is being called the “mini Code”, and while the power has been increased by about 7%, these are now the lightest four-piston production brakes.

What’s New

Well, the entire G2 brake has been redesigned so really it’s all new, but some of the main improvements are to the caliper, which suffers from less flex, less pad pocket, and a better piston seal caliper interface. Also, there is a new brake hose, new lever bearings, and bushings as well as an all-new brake pad compound called “Power Organic”.

Caliper

The caliper has been fully redesigned, taking what was implemented in the new Code caliper and moving it into the G2 package. There is a smaller pad pocket area, as well as the mounting points for the caliper, have been increased, creating less flex. The square piston seals have not changed but rather the amount of movement has been improved, and now controlled piston movement through the seals allows for consistent piston roll back and pad advancement.  The calipers also use Phenolic Pistons, which eliminates the need for the HeatShield that was previously used in Guide S4 calipers.

”Power Organic” Brake Pads

The addition to the brake pad line now includes the Power Organic brake pad. A new compound that provides more power than the original organic pad previously used, but still quieter than a metallic pad. This new pad will have a Lunar grey backing to help separate it visibly from other pads, and will also be available as an aftermarket upgrade to slap in your Guide brakes. There will still be the organic and metallic pad options, and pad shape has remained the same from Guide to G2.

Lever

The leverage rate and lever feel have not changed, as SRAM wanted to keep the same feeling that everyone has come to like with the Guide however, the pivot bushings and bearings have been updated. For the RSC, a new pivot dowel and bushings provide a stiffer connection that is felt through the lever, as well as some refined small parts that allow SRAM to lower the cost a bit on RSC brakes. For the Ultimate, there is new pivot bearings and a carbon blade that helps for a stiffer and snappier lever feel, helping reduce finger fatigue on the longest, steepest descents.

How Do They Perform?

We have been on the G2 RSC brakes for a few weeks now, and also had a solid multi-hour ride on the Ultimates as well. Coming from SRAM Code brakes, there wasn't much getting used to how the power is delivered, but also I was slightly skeptical as the Code brakes deliver a punch of power and I’ve really come to love the Code brake. The G2 really is the new “mini Code” as SRAM calls it. Initially, we went out and rode some of the steepest trails we have close to our shop in SoCal. Midway down the trail I had a hard time realizing I wasn't braking with Code brakes.

The power is very consistent and the lever feel is greatly improved. SRAM said this isn't a brake revolution, rather an evolution, and they are exactly right. It’s a solid step forward in braking power, about 7% actually. While 7% might not sound like a lot, I’d bet you’d take huge issue if you experienced a 7% loss in power with your current brakes. In other words, that small percentage is worth rejoicing over.

My favorite aspect of the new G2 brake is the new lever feel. It really is a bit snappier and has a great positive feel with a solid stop when the pads are fully engaged. Going from the Code to the G2, I could happily ride the G2 on my current 150mm trail bike on the steepest terrain. There were no issues with brake fade, power loss, or just not enough power. The G2 brake is a great second generation and really is the new “mini-Code”.

Pricing and Weights

• SRAM G2 RSC: $180 & weighs 255g with 850mm hose
• SRAM G2 Ultimate: $280 & weighs 242g with 850mm hose

Final Thoughts

The G2 brake is an amazing step forward and redesign of the original Guide brake. With all new parts, increasing power by 7%, and a new brake pad compound, Sram really hit the target. With competitive pricing and being some of the lightest 4 piston brakes on the market, backed by one of the best brands in the industry, it's hard to have anything bad to say. The G2 RSC and Ultimate brakes are a great option for your current trail or enduro bike.
