SRAM s XG-1351 XPLR E1 13-Speed 10-46 Cassette is built to deliver precise, consistent shifting across a wide 460% gear range. With tight cog spacing and a durable build, it s designed to meet the demands of modern 1x gravel drivetrains, providing the right gear for every surface, climb, and descent.Key Features and Benefits:13-speed configuration with tight 1-tooth jumps in the small cogs: This design maintains optimal cadence and smooth gear progression. It reduces abrupt shifts and helps maintain consistent speed and effort on mixed terrain.Wide 10-46T range (460%): Offers a broader spread of gears than a standard 12-speed cassette. It allows for better climbing gears without sacrificing top-end speed. This ensures you're prepared for steep climbs and fast descents alike.Nickel-chrome plated cogs: The plating enhances wear resistance and reduces chain noise. This leads to a quieter, more durable drivetrain that performs well over time in varied conditions.XDR driver body compatibility: Engineered to fit XDR freehub bodies, which supports the 10-tooth start cog. This allows for higher top-speed gearing within a compact cassette design.Compatible with Flattop chains: Designed for use with SRAM s 12/13-speed Flattop chains. This ensures optimal chain engagement, smoother shifting, and long-term drivetrain efficiency.Optimised for XPLR 1x drivetrains: Built to work seamlessly with SRAM s XPLR 1x 13-speed rear derailleurs. This ensures precise shifting and compatibility across the full XPLR gravel ecosystem.This cassette is aimed at riders who need a wide gear range without losing the close steps needed for cadence control. It pairs rugged reliability with technical precision, making it a smart upgrade for serious gravel riders using a 1x setup. With compatibility across Flattop chains, XPLR derailleurs, and XDR drivers, it integrates cleanly into modern drivetrains.Ready for steep climbs and fast flats, this cassette gives you the range, reliability, and precision to keep moving forward no matter what the trail throws at you.Specification:Speed (CS) 13Gearing 10-46tCog finish (Cassette) SilverTechnology (Cassette) XGCog sizes 10-46t: 10,11,12,13,15,17,19,21,24,28,32,38,46Drivetrain Configuration 1xCassette Size (Max) 46Cassette Size (Min) 10Chain Technology Road Flattop D1, Road Flattop E1Rear Derailleur Mount MTB, Road, Road L, UDH
