Praxis 40T Direct Mount Black Wave Road

Praxis 40T Direct Mount Wave Road Chainring Black is a premium 1X drivetrain chainring designed for road, gravel, and cyclocross riders who demand reliable chain retention, lightweight efficiency, and long-lasting durability. Engineered with advanced Wave™ tooth profile technology, this chainring delivers superior chain security and smooth drivetrain performance across muddy cyclocross races, rough gravel rides, and fast-paced road adventures.

Developed in collaboration with Mountain Racing Products, the Wave™ tooth profile applies alternating lateral force to each chain link to actively retain the chain more effectively than traditional narrow-wide designs. The open tooth design also improves mud, grit, and debris evacuation, helping maintain drivetrain reliability in challenging riding conditions.

Precision CNC-machined from premium 7075-T6 aluminum and finished with a hard black anodized coating, the chainring offers excellent strength, wear resistance, and lightweight performance for high-mileage riding. The 40T gearing provides an efficient balance between climbing capability and high-speed performance, making it ideal for gravel racing, cyclocross, endurance riding, and 1X road setups.

Compatible with Shimano, SRAM, and KMC 10, 11, and 12-speed chains, the Praxis Wave Road Chainring is designed specifically for Praxis 3-bolt direct mount road cranksets.
