The Descendant 7K crankset delivers consistent performance every time. The Descendant crankset with SRAM X-SYNC2 tooth profile chainring is designed for complete chain control. The thickness of each tooth is precisely toleranced and controlled to work seamlessly with the inner and outer links of the SRAM chain. SRAM DUB technology features a better engineered bottom bracket and a new spindle design. Together, these allow for a more consistent approach to bottom bracket assembly, a better seal against contamination and better forward and backward compatibility. Now everyone can benefit from a new level of durability. - Intended use: MTB - Details: - The SRAM DUB technology features a unified approach to the bottom bracket mounting, a better seal against dirt and a forward and backward compatibility - Optimized arms made of forged aluminum 7000 series chainrings - Number of chainrings: 1 chainring crank - Chainline: 56.5 mm - Compatibility circuit: 12-speed - Type: Direct Mount crankset - Axle mount: DUB (28.8 mm) - Bolt circle: without bolt circle mm - Type of bolt circle: without bolt circle.
