The ultimate weapon for time trials and speed records!
This Dura-Ace 56T chainring is not available for retail sale. Coming directly from the "Service Course" stock of a professional team, it was designed to meet the raw power requirements of the world's best riders.
With 56 teeth, it offers a monumental gear ratio for Time Trials (TT) or Triathlon, allowing for reduced friction by staying in the middle of the cassette at high speeds.
