SRAM X-SYNC RED E1 Aero Direct Mount Chainring | 12s
Unleash your full potential against the clock with the SRAM X-SYNC RED E1 Aero Direct Mount Chainring, the pinnacle of performance engineering for dedicated road cycling, time trial, and triathlon athletes. Designed as an integral part of SRAM´s revolutionary 12-speed ecosystem, this chainring is crafted not just to transfer power, but to slice through the air with ruthless efficiency. Every rotation is an investment in speed, providing the aerodynamic advantage you need to shatter personal records and gain precious seconds when it matters most.
Experience the perfect synthesis of form and function. The RED E1 Aero chainring’s design is a masterclass in aerodynamics, minimizing drag to help you maintain higher speeds with less effort. This focus on wind-cheating performance makes it the ultimate upgrade for any serious competitor looking to optimize their setup for race day. When combined with the SRAM RED groupset, it creates a seamless, efficient, and visually stunning drivetrain built for pure velocity.
Our light, stiff, and durable direct mount chainrings let you pick the exact gearing you want and quickly swap sizes. Our X-SYNC technology keeps the chain where you need it to be, too. The Direct Mount system enhances this performance by creating a lighter and stiffer platform compared to traditional spider-based designs. This results in more direct power transfer from your legs to the road, ensuring no watt is wasted. The intelligent design also allows for effortless customization, enabling you to swap chainring sizes quickly to tailor your gearing perfectly for different courses and conditions.
At the heart of its unmatched reliability is SRAM´s proprietary X-SYNC technology. The wide-tooth, narrow-tooth profile engages the chain with surgical precision, providing phenomenal chain retention and control even on less-than-perfect road surfaces. This security allows you to focus completely on your power output, confident that your chain will remain securely in place. This chainring also integrates flawlessly with X-Range gearing technology, which delivers a wider gear range and a more logical, smoother progression between shifts. This intelligent system ensures you are always in the optimal gear, whether climbing, accelerating on a flat, or powering down a descent.
