Driven by the project's goals of light weight, higher efficiency, and advanced materials, for the second year in a row SRAM created the lightest, most advanced shifter in the world. Built around SRAM's revolutionary DoubleTap technology, the new SRAM Red DoubleTap controls are designed to exceed the needs of even the most serious racers. The Red Shifter uses a highly developed version of DoubleTap, which is enhanced by new pawl geometry that results in zero-loss travel. Additionally, the Red front shifter mechanism gains a new trim feature to optimize chainring selection. With less effort, Red controls deliver faster shifts, more precisely.

The shifter's ergonomic design factors in comfort and light weight, with a ground-breaking brake and shift lever reach adjustment capability that allows you to achieve a more natural, aggressive, and comfortable riding position. Additional refinements in the lever's design further improve shifting efficiency and performance, as does an even lower weight than its already-light SRAM Force counterpart. These refinements include Dual Cable Routing, so no matter what type of bars you use, you don't have to compromise comfort for performance. SRAM Red DoubleTap controls also take advantage of a redesigned trim feature that gives you precise adjustment and greater compatibility with the big ring.

Light weight, precision, and fluid performance put the new SRAM Red Rear Derailleur in a class of its own. Based on the already-superior design of the SRAM Force Rear Derailleur, the Red offering delivers even greater advantages thanks to a diet of structural carbon and titanium. Hybrid ceramic bearing pulleys and titanium parallelogram pivot bearing refinements further supercharge the overall component speed, accuracy, and durability. Amazingly, these design choices yield an astonishing 153g mechanism.

Fatigue, flex, and friction, enemies all, and they'll rob you of speed and performance over both the short and long hauls. The SRAM Red Crankset does its part to keep them from affecting your ride. The integrated carbon spider's design is lightweight and extremely stiff, allowing for instant, efficient power transfer.

Speed-sapping friction? The Red Crankset virtually eliminates it with new hybrid ceramic bearings housed within the GXP^TM BB's case. Ceramic bearings ride in a stainless steel race, are more efficient, use a lighter seal, and are lighter, stiffer, and longer-lasting than normal bearings.

Matched to the new crankset is an equally revolutionary pair of chainrings. Optimized exclusively for Red components, they're stiffer than anything ever before, for greater efficiency as well as incredible power-transfer ability. The Sram GXP Team Ceramic BB must be purchased seperately.

The end result: a crank that's evolutionary in its design and revolutionary in its ability to put you at the front of the pack no matter which size you choose. .

SRAM's GXP Ceramic BB Bearings exceed the needs of even the most demanding riders. They offer a performance advantage over traditional bottom bracket bearings that's almost too great to believe. Besides being 10% lighter than standard bearings, ceramic bearings require an astonishing 78% less energy than the next most efficient BB on the market.

Ceramic bearings are more resistant to dirt and moisture and, when properly maintained, will outlast and outperform any other BB on the market. They utilize a lighter-than-normal seal along with stainless steel races and high-polish cups and have no equal when it comes to helping you reach terminal velocity more quickly and easily than ever before.

SRAM's Red Front Derailleur takes precision shifting to its limits, offering the smoothest up- and downshifting. Bolstered by a NEW hardened titanium cage, shifting and trimming are fast, easy, and smooth as silk across the entire range for both traditional and compact ring sets.

The perfect complement to the Red gruppo's ability to gather and maintain speed, the Red Brakeset offers superior stopping power and modulation in a light, windcheating package. Based on a new, upgraded version of SRAM's race-proven skeletonized Dual Pivot design, these brakes bring cold-forged aluminum arms, alloy pivot bolts, and an easy-to-adjust padset together for maximum effectiveness with minimum weight. Plus, modulation and power control are feather-light and extremely weatherproof, a benefit of their new high-precision bearings.

There are times when the simplest solution is the best one. In the case of the new OG 1090 Cassette, simplicity also means elegance, efficiency, and performance. SRAM took up the challenge of re-engineering the cassette from a component made up of many parts down to strippeddown but exceptionally strong set of cogs that stick firmly to SRAM Red's core principles of light weight, higher efficiency, and maximized technologies.

The main cogset of the OG 1090 cassette is machined out of a single forged form that is heat treated and then shaped in a complex series of CNC-guided operations never before seen in this type of application. This is truly a revolutionary design that will take you by surprise with its ingenious simplicity. The sprockets themselves (including two free cogs) have all been designed with SRAM's proprietary OpenGlide^TM design for smooth-as-silk up- and downshifts. Weight, stiffness, and strength-wise, the radical OG 1090 Cassette delivers titanium's desireable weight, with solid steel's superior strength and stiffness.
