Praxis Works Forged Chainring Set – 130mm, 39/53T (2-Tone Buzz)

The Praxis Works Forged Chainring Set delivers top-class, performance-proven replacement chainrings for high-end road cycling. Designed for 5-arm standard, mid-compact, compact, and cyclocross setups, these chainrings combine durability, precision, and flawless shifting.

Manufactured using One-Shot Cold Forging, Praxis creates complex tooth profiles with alternating tooth angles, synchronized ramps, and strategically placed shift pins—features unattainable with traditional CNC machining. This process produces harder, more durable teeth while maintaining smooth and reliable shifting.

Praxis’ LevaTime® Shifting Technology ensures perfectly timed lifts by synchronizing the ramps with the inner ring, providing a clean channel for chain movement. This set is offered in the stylish 2-Tone Buzz finish for a premium aesthetic.

Note: Not compatible with Campagnolo/Fulcrum Ultra-Torque/Racing Torque cranks. The 39/53T set is custom-made for Praxis Works branded 110BCD road cranks and the new Specialized alloy 110BCD spider. Custom bolts are included for proper installation. This set will not fit prior-generation TURN cranks or other brands.
