The latest version of the SRAM Red Aero chain is even lighter. Thanks to the new Exogram technology process, the weight has been reduced by a few grams, mainly due to the hollow carbon fiber outer plates. The weight reduction compared to the previous generation reaches up to 29 grams. The carbon not only allowed for low weight but also significantly increased the stiffness of the construction, effectively transferring power during riding. The aerodynamic chain, following the latest trends, operates exclusively with a 1x12 drivetrain system, and its single-chain design cuts through the air, which will be appreciated by all those competing for seconds in time trials or triathlons. Complete chain control, even on rough terrain, has been achieved thanks to the combination of wide and narrow teeth. Attention should be given to the chain’s Direct Mount system, which reduces aerodynamic drag. The DUB axle, with its increased diameter, offers much greater stiffness. Additionally, there is the option to install a power meter, which will help improve training and increase performance.
