SRAM EX1 E-MTB Drivetrain – Built for Electric Mountain Bike Performance

Engineered to conquer the unique challenges of e-mountain biking, the SRAM EX1 drivetrain delivers robust power transfer and smooth shifting under high-torque conditions. Unlike traditional MTB drivetrains, it’s optimized for the low-cadence, high-power demands of e-bikes, ensuring durability and reliability on rugged trails.

Key Features for E-Bike Riders

  • X-Horizon Design: Reduces chain slap and enhances efficiency for seamless 1x performance.
  • Wide Gear Range: Larger jumps between gears provide optimal cadence control for climbing and acceleration.
  • E-Bike Tough: Reinforced components withstand the extra torque of electric-assist systems.
  • Quiet & Low-Maintenance: Borrowing tech from SRAM’s premium MTB groupsets for smooth, hassle-free rides.

Ideal for aggressive trail riders and e-MTB enthusiasts who demand precision and longevity from their drivetrain. Whether tackling steep climbs or fast descents, the EX1 ensures consistent power delivery without compromising on noise or wear.

Why Choose EX1 Over Standard Drivetrains?

Feature EX1 Drivetrain Conventional MTB Drivetrain
Torque Handling High (e-bike optimized) Moderate
Gear Spacing Wider jumps for e-bike cadence Tighter ratios
Chain Retention X-Horizon reduces slap More prone to slippage
Durability Reinforced for e-bike stress Standard construction

Upgrade your e-MTB with a drivetrain designed to match its power—ride harder, shift smoother, and go further with SRAM EX1.
