Sugino Zen Track Chainring 144mm - 51T through 54T

The Sugino Zen Track Chainring 144mm is machined for the velodrome — a competition-grade ring built to the tolerances that matter when you're driving maximum power through a fixed drivetrain with no shifting ramps to hide imperfections. The 144mm bolt circle diameter is the track standard, and the black anodized finish keeps weight down while adding genuine corrosion resistance.

Available in 51t through 54t, the Zen covers the gearing range most track riders work within — from the shorter ratios suited to pursuit and points racing to the bigger gears favored in flying 200m events. Sugino has supplied track components to Olympic and World Championship-level programs, and the Zen sits at the upper end of their track range, where chain engagement consistency and torsional stiffness are the priorities that shape every machining decision.
