Specific cups and variants are available for Cannondale-compatible frames and other proprietary interfaces. * Designed for compatibility with all SRAM DUB cranks, offering a consistent interface and chainline options for road, gravel, MTB and fatbike builds. Ideal for riders seeking a durable, serviceable upgrade that streamlines crank-to-frame fitment.
