SRAM Eagle 90 Transmission Crankset

Built for strength, reliability, and flexibility, the Eagle 90 Transmission Crankset combines forged aluminium crank arms with 8-bolt chainring compatibility for secure, efficient power transfer. A stamped steel T-Type chainring delivers long-term durability, while optional dual bash guards offer added protection for technical trail use. With crank lengths available down to 155mm, it supports precise fit and greater control across a wide range of setups.

Key Features and Benefits:

• Forged aluminium crankarms with 8-bolt T-Type chainring compatibility: The forged construction provides a high strength-to-weight ratio, withstanding heavy use without adding unnecessary bulk. The 8-bolt interface ensures a firm and consistent connection to the chainring. This combination delivers stable, reliable power output across variable terrain.
• Stamped steel T-Type chainring included: The steel chainring resists wear and deformation under load, maintaining performance over time. Its stamped construction increases material density and toughness. This results in fewer replacements and reduced drivetrain maintenance.
• Independently removable dual bash guards: These composite guards mount on either side of the chainring and are matched to specific sizes. They protect the chainring from impact during trail riding. This extends the life of drivetrain components and reduces the risk of mechanical damage in rough conditions.
• Crank lengths in 175mm, 170mm, 165mm, 160mm, and 155mm: A wide range of lengths enables riders to fine-tune fit and pedal dynamics. Shorter options improve ground clearance and support a lower centre of gravity. This enhances control and reduces pedal strikes on technical climbs and descents.
• Compatibility with GX and X0 T-Type chainring bash guards: Shared hardware and sizing offer easy replacement and interchangeability. Riders using other Eagle Transmission components can carry fewer spares and streamline setup. This makes maintenance more efficient and system integration easier.
• DUB Wide spindle for 55mm chainline (55CL): The DUB Wide spindle standard centres the drivetrain for modern frame designs. This increases rear tyre clearance while preserving chain alignment. The result is better shifting performance and frame compatibility with wider setups.

Designed for riders who need a crankset that holds up under pressure, the Eagle 90 delivers long-term durability and consistent power transfer. Its forged construction, steel chainring, and impact protection features work together to reduce failure points during sustained use. The range of lengths also supports riders aiming to optimise fit for better control and responsiveness on the trail.

Choose a crankset that combines strength and compatibility across your drivetrain. The Eagle 90 is made to handle tough terrain without compromise—ride after ride.
