SRAM Rival E1 XPLR DUB Crank Arms
The SRAM Rival E1 XPLR DUB Crank Arms are a robust and affordable solution for gravel cyclists looking to build or upgrade their drivetrain. These crank arms are made from aluminum and feature a cutout to reduce weight. The Rival E1 crank arms use SRAM’s 8-bolt direct mount interface for chainrings and a 47.5 mm gravel chainline. They are available in lengths from 160 mm to 175 mm and fit DUB bottom brackets.
Product Details
Key Features of the Rival E1 XPLR Crank Arms
- Lightweight Aluminum Construction: Engineered with a cutout for weight savings without compromising on stiffness.
- DUB Wide Spindle: A versatile and durable spindle designed for gravel frames.
- 8-Bolt Mounting Interface: An 8-bolt interface means you have a wide variety of options for chainrings and power meters.
Compatibility
The Rival E1 XPLR Crank Arms are compatible with chainrings and power meters that use SRAM’s 8-bolt interface. This crankset uses a DUB Wide spindle. See Compatibility tab for more information
Considerations
Because this is SRAM’s entry level offering, SRAM Force and RED crank arms are made from carbon and are lighter, but more expensive. These crank arms are also only designed for gravel frames and groupsets.
Advice From Our Staff
We believe the SRAM Rival E1 XPLR Crank Arms are a great choice for gravel cyclists running a SRAM drivetrain who want a cost-effective, aluminum crankset. Because they are made from aluminum, they are more durable than carbon cranksets which can be beneficial for those riding in terrains with lots of rocks and roots.
