SRAM Rival XPLR Wide E1 Cranksets

SRAM Rival XPLR Wide E1 Cranksets

SRAM Rival XPLR Wide E1 Cranksets (FC-RIV-1W-E1) stands as SRAM’s most advanced aluminum 1x gravel crankset. Built directly to service both high-performance 12-speed and cutting-edge 13-speed gravel drivetrains, this lightweight alloy crank handles everything from fast-paced fire roads to demanding, mud-soaked backcountry routes. By removing excess weight and utilizing an optimized stiffness-to-weight profile, the Rival XPLR E1 delivers instant power transfer and rugged structural reliability without breaking the bank.

Key Advantages

• Massive Tire Clearance (Wide Configuration): Built with an extended DUB spindle that moves the chainline outward by 2.5mm (47.5mm chainline). This adds massive clearance for aggressive, ultra-wide gravel tires up to 2.1 inches without risk of frame or rubber contact.
• Flawless 12 and 13-Speed Versatility: Fully future-proofed to operate seamlessly alongside both 12-speed and 13-speed XPLR rear derailleurs and chains.
• Unbeatable X-SYNC Chain Retention: Equipped with a solid aluminum Direct Mount chainring utilizing narrow-wide tooth architecture. This profile mechanically locks onto your chain to eliminate drops on punishing, bumpy terrain.
• Stiffness-Optimized Alloy Construction: Features a heavily revised, modern aesthetic over previous generations that sheds over 50 grams while focusing material density strictly where high-torque rigidity is required.
• Universal DUB Frame Integration: Designed around SRAM’s standard-setting DUB spindle ecosystem. This single spindle design guarantees maximum bearing durability, excellent contamination sealing, and cross-compatibility with nearly every bottom bracket standard.
