SRAM developed an all new road race group set, called the New Red. According to SRAM each element of the Red group has been redesigned and features new technologies. Less weight and improved noise reduction were key elements in this process.
SRAM’s engineers managed to reduce the weight of the complete group set from just under 2,000 grams to less than 1,800 grams.
The New Red will be available to the after market next March. The New Red rear derailleur is designed with SRAM’s Exact Actuation technology for precise, efficient shifting. To save weight SRAM paid attention to details; adding a hollow titanium anchor bolt and refining the tooth geometry of the jockey wheel.
To eliminate the need for shifter trim on the front derailleur SRAM developed the Yaw technology. The new cage does not simply move back and forth, but actually rotates to maintain a consistent angular relationship with the chain.
The Red Exogram Crankset is completely hollow all the way to the spider. Its hidden bolt pattern makes better use of carbon fiber to further improve stiffness and shed weight. To reduce the frontal area, the new brakeset has been created with a host of aerodynamic features.
The patented AeroLink also improves braking performance and modulation. The Red Powerdome cassette is super light and very quiet. Just like its predecessor the eight cogs in the middle are machined from a single block of steel. New are the StealthRing elastomers between each cog to reduce vibration and noise.
Next autumn SRAM will enlarge the Red group set with a hydraulic rim and disc brakes, especially for cyclocross. Electronic shifters aren’t in the offing for SRAM at the moment. The components manufacturer first wants to experience how the market picks up this product and how OEMs will handle assembly issues.
