Praxis Works MTB 1x 104 BCD NW Chainring

The Praxis Works MTB 1x 104 BCD NW Chainring is a durable drivetrain upgrade built for secure chain retention, long wear, and consistent performance across MTB and e-MTB use. It combines a narrow-wide tooth profile for chain stability with a threaded M8 interface for improved motor clearance, while finish options include a hard-wearing PVD coating to extend service life under high torque loads.

Key Features and Benefits:

• Cold forged 4130 high-grade steel construction: Cold forging compacts the steel structure to improve strength and durability. This increases resistance to wear and deformation under high torque, resulting in longer service life and reduced replacement frequency in demanding riding conditions
• Narrow-wide tooth profile design: Alternating tooth widths match chain links precisely, creating a tighter hold on the chain. This reduces chain movement and drop risk, leading to more stable pedalling and consistent drivetrain performance on rough terrain
• Threaded M8 chainring interface: The female-threaded design allows the chainring bolt to thread directly into the ring. This improves clearance around e-MTB motors and simplifies installation, resulting in a cleaner setup with fewer parts and secure mounting
• Standard Black oxide finish: The black oxide coating protects the steel surface from corrosion and general wear. This maintains structural integrity over time and ensures reliable performance in mixed weather and trail conditions
• Silver PVD coated finish: Physical Vapour Deposition creates a hardened outer layer that increases surface hardness and corrosion resistance. This reduces tooth wear under high torque loads, extending drivetrain lifespan and maintaining consistent engagement over time
• Wide drivetrain compatibility: Designed for Shimano, SRAM, and KMC chains across 10, 11, and 12-speed systems. This allows easy integration with mechanical and electronic drivetrains, ensuring flexibility when upgrading or replacing components

Consistent chain control and long component life are critical when running a 1x drivetrain, especially under higher loads. The combination of a secure tooth profile, reinforced steel construction, and finish options designed to resist wear ensures reliable power transfer and reduced maintenance. The threaded interface also supports cleaner installation on modern frames and e-MTB systems.

This chainring is a practical choice for maintaining drivetrain stability and reducing wear over time, making it well suited for riders who want dependable performance with minimal upkeep.
