SRAM RED Road Chainring Direct Mount 2x12-speed black

Deep Range
Racing bikes and their riders are faster and more powerful than ever before. But the gear ratio of our bikes has not kept pace with this change. It has been limited by tradition. With the sole aim of improving the modern riding experience on the road, we have completely redesigned the road bike gear ratio.
The new Deep Range technology. Not only does it offer more gear ratio bandwidth, but this bandwidth is also better. It has "depth": a smoother, more useful gear graduation. Intelligent shift settings, enabled by AXS, bring the simplicity of a 1-speed drive to 2-speed. So you always have the right gear and the gear ratio does not stand in your way. Drive faster, more efficiently and more comfortably with Deep Range technology.
