digirit TRACK CARBON CHAINRING

Unlike keirin, where parts are restricted by the NJS standard, track racing sees not only the athletes competing but also various frame and parts brands vying with the latest technologies. This particular part has caught the attention of the competitive world as well. Upon seeing it, everyone invariably asks the same question: "Is a carbon chainring safe?" I had the same concern and approached everything with skepticism.

The manufacturer claims it undergoes durability testing of 25,000 kilometers without wear. Doubting this claim, I intentionally subjected a used chain to 1,500 kilometers of abuse without lubrication, but as seen in the photo, there were no signs of wear. The resistance to everyday wear and tear is remarkable.

While riders like us who ride in the city might not use the "ultra-weight gear ratios (even over 5.0)," riders who push hard on them have no need to worry about strength concerns.

I was also concerned about noise due to its irregular tooth shape compared to the familiar Sugino products, but it proved to be just as quiet as the ZEN series, if not better.

The Canadian national team was quick to adopt it and has used it in races, with plans for supply to other national representative teams in various countries in the future. (Apologies for the vague information about gear ratios, adopting teams, countries, athletes, etc., as much of this information cannot be disclosed.)

Above all, its aesthetics complement frames handled by BROTURES, such as LEADER®️ and DOSNOVENTA, as well as disc-shaped direct cranks like ROTOR, VISION, and MICHE, very well.
