The SRAM Rival AXS E1 DUB Crankset is SRAMs most advanced aluminum road crankset, designed to maximize stiffness while minimizing weight. Material is precisely removed from the crankarms, cutting over 50 grams compared to the previous generation without sacrificing strength. Integrated chainrings deliver crisp and accurate front shifts for consistent performance under load. X-Range gearing provides a broader range and smoother progression to help maintain cadence across varied terrain. The DUB bottom bracket system enhances durability and simplifies compatibility across different frames. The crankset is available in 48/35T and 46/33T combinations to match a variety of gearing preferences.
