Pure Mechanical Precision

SRAM delivered the dream of the perfect mountain bike shift, and now that dream is mechanical. Eagle 70 Transmission delivers incredible mechanical shifting performance, responding instantly to every pedal stroke, so the harder you push, the smoother it shifts. No derailleur hanger. No adjustment screws. No batteries to keep charged. Just pure durability, reliability, and affordability.

Unrivaled Durability

Built tough from the ground up, the Eagle 70 derailleur mounts directly to the frame using our ultra-strong Full Mount interface. It’s so strong, you can stand on it. Paired with a tool-grade steel chainring and T-Type tooth profiles for unmatched chain retention and longevity, this drivetrain is designed to withstand anything the trail throws at you. Add an optional single or dual bash guard for even more protection and extended ride life.

Effortless Maintenance

Less time wrenching, more time riding. Eagle 70 is low maintenance and easy to care for – just keep it clean, lube the chain, and swap cables when needed. Thats it. No headaches, no complications, just consistent, worry-free performance.

Shift Without Limits

Whether you’re hammering up a climb or pushing the watts on an E-MTB, Eagle 70 shifts without hesitation, even under full power. With X-Sync tooth profiles and 44 precisely designed shifting points on T-Type cassettes, you’ll experience the smoothest, most precise mechanical shifting under load ever.

The Perfect Mechanical Cockpit

Nothing beats the satisfying, tactile click of a perfect shift. Eagle 70s refined ergonomics and streamlined stealth-mounted shifter pair seamlessly with SRAM brakes and dropper levers for a clean, integrated look that enhances your ride experience.

Eagle 70 is more than just a drivetrain, its mechanical shifting, redefined.
