$29.58
Description
The Truvativ Descendant 7K crankset is a precision-engineered component designed to deliver unmatched control for mountain bikers tackling rugged terrain or high-speed descents. Built for seamless integration with SRAM’s Eagle drivetrain system, this crankset combines cutting-edge technology with durable materials to enhance performance in demanding conditions. Its core innovation lies in SRAM’s DUB platform—a streamlined spindle interface that simplifies bottom bracket compatibility while improving sealing against mud and debris for smoother shifts under pressure. Whether you’re navigating technical singletrack or charging through enduro stages, the Descendant 7K ensures consistent power transfer thanks to its direct-mount X-SYNC 2 chainring geometry.
The X-SYNC 2 chainring’s engineered tooth profile grips the SRAM Eagle chain securely, minimizing slippage even during aggressive acceleration or steep descents on loose surfaces like gravel or wet roots. Paired with an optimized 56.2mm chainline tailored for SuperBoost+ hubs (157mm spacing), this setup sharpens pedaling efficiency while maintaining stability across 12-speed gearing systems—a must-have for modern trail and all-mountain builds. Crafted from forged 7000-series aluminum arms, the Descendant 7K balances lightweight construction with rugged durability, ideal for riders prioritizing strength without excess bulk on long adventures or race days.
Designed specifically for mountain biking’s toughest demands, this crankset offers single-ring setups with a 32-tooth configuration perfect for climbing technical trails before unleashing speed downhill. The black finish provides a sleek aesthetic while resisting corrosion from frequent exposure to dirt and moisture common in off-road riding environments. With a standard 9/16″ pedal spindle interface (BB sold separately) and available in 165mm lengths, it adapts seamlessly to your existing build without compromising performance metrics like stiffness or weight distribution compared to bulkier alternatives
