The most advanced evolution of the renowned D.I.D Racing Pro - Track Racing chain, the D.I.D Racing Pro 2 G&S x 116BJ (with BJ screw-type joint included) is engineered for professional Keirin racing and fully NJS-approved (Nihon Jitensha Shinkōkai).
Striking the perfect balance between lightweight design and structural integrity, every single millimeter of this chain has been optimized with a single goal: to guarantee maximum power transfer with zero energy loss.
This is not just theory: the Racing Pro 2 is already the official choice of some of the most successful federations and teams in the world, including the award-winning TeamNL Track Cycling (Dutch National Team) and the elite riders of Japanese Keirin.
Ultra-Fine PTFE Coating: Featuring high-density polymer particles on the bushings, this coating facilitates smooth sliding between the pins and bushings, reducing friction and maximizing power transfer.
Lightweight & Strength Without Compromise: Thanks to its hollow-pin structure (with zero protrusions), the Racing Pro 2 is lighter than conventional models, saving 27 grams with a total weight of just 375g. This weight reduction is achieved while fully meeting and exceeding the strict JIS/ISO standards for stiffness and structural integrity.
Aerodynamic Efficiency & High-Intensity Performance: The revolutionary pin design drastically reduces air resistance and ensures optimal transmission smoothness during ultra-high-intensity efforts such as Sprint, Kilo, Team Sprint, and Keirin. The prestigious Silverstone Sports Engineering Hub (SSEH) recognizes the Racing Pro 2 as the highest-performing chain among the products in its category.

Waxing and ultrasonic cleaning are suitable for this type of chain, as they do not cause the PTFE coating layer to detach.
However, excessively thick waxing should be avoided, as it may cover the PTFE coating and compromise the low-friction performance provided by the coating.
