SRAM RED E1 XPLR DUB Wide Crank Arms
The SRAM RED E1 XPLR DUB Wide Crank Arms are SRAM’s lightest and stiffest cranks. These crank arms use SRAM’s DUB Wide spindle for additional tire clearance and an 8-bolt direct mount interface. This makes them compatible with 1x 8-bolt direct mount chainrings and power meters. In addition, they are now available in sizes as short as 160 mm.
RED E1 XPLR Wide Crank Key Product Details
Compatibility:
The SRAM RED E1 XPLR Crank Arms are compatible with chainrings and power meters that use the SRAM 8-bolt chainring interface. This crankset uses a DUB Wide spindle.
Key Features:
Lightweight carbon fiber crank arms, DUB Wide spindle, power meter compatible and SRAM 8-bolt chainring interface.
Advice From Our Staff:
These crank arms are best-suited for gravel riders who are looking for an ultralight crankset for their 1x gravel drivetrain. SRAM has taken the best tech from their road crank arms and used it to build these lightweight, durable gravel cranks. In addition, we like that these cranks as they can be run as an analog crankset without a power meter or easily upgraded to include one.
