SRAM Rival XPLR E1 DUB Wide Direct Mount 1x Crankset

The SRAM Rival XPLR E1 DUB Wide Direct Mount 1x Crankset delivers maximum chain control, cross-compatibility, and efficient power transfer in a precision-engineered aluminium design. Its direct mount chainring, wide chainline, and extended spindle combine to offer unmatched drivetrain stability, reliable fit across frames, and reduced weight without sacrificing stiffness.

Key Features and Benefits:

• Direct mount chainrings in sizes from 38T to 46T: Enables a clean interface between crank and ring, reducing weight and complexity. This simplifies maintenance while improving power transfer across the drivetrain.
• SRAM X-SYNC wide-tooth, narrow-tooth chainring technology: Uses alternating tooth profiles to grip each chain link securely. This results in maximum chain retention and fewer dropped chains under load, ideal for rough gravel terrain.
• Wide chainline design: Positions the chainring further out from the frame for compatibility with Full Mount derailleurs. This supports smoother shifting and better drivetrain alignment when used with modern gravel or MTB-style setups.
• DUB bottom bracket spindle interface: Offers a stiffer, larger diameter spindle with better bearing integration. This increases durability, reduces friction, and keeps the drivetrain running smoothly in all conditions.
• Extended DUB crank spindle: Accommodates both Road and MTB bottom bracket widths. This ensures the crankset can be fitted to a wider range of frames without adapters, making it highly versatile.
• Supports 135mm, 142mm, and Boost rear spacing: Provides rear axle compatibility across a wide variety of frames. Riders benefit from greater flexibility in bike setup without needing to compromise drivetrain performance.

Designed for riders who value drivetrain security, frame compatibility, and low-maintenance reliability, this crankset offers a balance of strength, precision, and adaptability. The wide chainline, X-SYNC technology, and versatile spindle length work together to deliver consistent performance across varied terrain and frame types.

Upgrade your gravel drivetrain with confidence. This crankset delivers reliable chain control, wide fitment compatibility, and lightweight strength in one streamlined unit.
