After a year of hard work by the R&D team, KMC TT12 Racing won the 2025 Silver Award under the strict review of the Taiwan Boutique Review.

In response to the high-end road bike market demand, KMC has surpassed itself by developing the TT Racing Chain with the goal of being the "fastest." This chain allows top road bike and triathlon riders to feel a significant upgrade, fully utilizing their daily training results in competitions.

To achieve maximum transmission efficiency, the TT Racing Chain features a new double-bridge design with thin inner and outer chain plates, precisely accommodating the limited space of 11/12-speed cassettes commonly found on the market. The chamfered waist design of the chain plates seamlessly matches the new thick-thin chainrings available today. Whether starting from a standstill or shifting gears due to terrain changes, the TT Racing Chain always perfectly engages with the chainring teeth, driving the cassette for acceleration and reducing tooth interference, capturing every shift moment accurately. Additionally, the TT Racing Chain relies on the best steel toughness and strength, and through multiple refined processes, it further provides riders with optimal pedaling efficiency, reducing kinetic energy loss. It is also compatible with the chainring and cassette tooth profiles of the three major transmission systems: SRAM, Shimano, and Campagnolo. Tests have shown that during high-speed cruising at 45 km/h with a 100 kg load, the TT Racing Chain can save riders at least 5% more kinetic energy loss compared to competitors. Therefore, whether starting, sprinting, or cruising at high speeds, the TT Racing Chain consistently maintains high-level output, further enhancing rider control stability and safety for optimal performance.

The award for the TT Racing Chain is not only a significant recognition for the KMC R&D team but also represents KMC's alignment with the market, always listening to the needs of cyclists. KMC will continue to uphold the spirit of "ONE CHAIN FOR ALL," continuously developing the most suitable bicycle chains for cyclists.
