Know before you buy
The Red E1 is engineered for maximum power transfer efficiency. Its stiff construction ensures that the energy you put into your pedal stroke is translated directly into forward motion with minimal flex.
Crank length is typically chosen based on your inseam and riding style. Shorter cranks, like 160mm or 165mm, can improve hip clearance and cadence, while longer options like 175mm may provide more leverage for riders with longer legs.
This assembly is specifically optimized for SRAM's advanced, high-performance drivetrains. It is best suited for riders looking to upgrade their existing high-end setup to ensure full compatibility and precision shifting.
No, the Red E1 Crank Arm Assembly is sold as the crank arms only. You will need to ensure you have the appropriate chainrings and a compatible bottom bracket to complete the installation.
The E1 generation focuses on refined material stiffness and weight optimization. It is designed to meet the demands of modern competitive cycling where every gram and watt of efficiency counts.
