Its weight is comparable to Shimano Dura-Ace level chains, and it delivers smooth, precise shifting while offering one of the most extensive colour selections in the high-end chain market. The Pro SL stands out for its industry-leading customisation, letting you match your drivetrain to your frame and components, something rarely offered in a high-performance chain. Despite the visual options, it keeps race-level durability and efficiency. Precision machining and surface treatment give consistent, low-friction performance across drivetrain systems, whether for road racing or a high-end custom build. Each chain undergoes strict tensile strength testing, coating inspection and wear resistance validation to ensure consistent quality and long-term reliability.
