Three decades ago, SRAM was founded on a product called Grip Shift and an idea that shifting a bike should be easier, better and more intuitive. It’s more advanced than the original, but the XX1 Eagle Grip Shift follows in the same tradition of making shifting easier, better and more intuitive. The XX1 Eagle Grip Shift system includes robust internals that make it more durable and its shifting performance more precise. But just like the original, it is total control in the palm of your hand.

Sometimes less is more. With the 10-speeds, an 11-48T range, and evenly spaced gear steps, the ADVENT X cassette allows riders to shift less often to find the right gear, while still having enough range to ride what they want. Fewer cogs also means less weight and a wider chain for better mud shedding. It even fits on standard 10-speed freehub bodies so you don't need to buy new wheels for no reason. In short, it's everything you want in a high-end drivetrain. - Two alloy large cogs and a full alloy spider eliminate unwanted weight - Ramped cogs aid in shifting under load - Continuously molded construction maintains straightness and durability - Compatible with standard HG freehub bodies and 10-speed chains - Cassette Body Type: Shimano/SRAM 8, 9, 10 Speed - Cassette Cogs: 11-13-15-18-21-24-28-34-40-48
