Praxisworks MTB eRing Chainring

E-bikes generate significantly higher torque and power loads than standard mountain bikes, which accelerates wear on aluminum chainrings. The 4130 steel construction provides the necessary hardness and durability to withstand these forces, ensuring the ring lasts much longer before needing replacement.

Yes, the Praxisworks eRing is fully compatible with 1x10, 11, and 12-speed systems, including SRAM Eagle, Flat, and T-type chains. The narrow-wide tooth profile is specifically engineered to maintain secure chain retention across these modern drivetrains.

The female-threaded design allows you to bolt the chainring directly to your e-bike motor spider using a standard M8 bolt. This eliminates the need for extra nuts or spacers, ensuring proper clearance and a clean, secure fit on compatible motor systems.

While the narrow-wide tooth profile offers excellent chain retention on its own, we strongly recommend using an upper chain guide if you frequently ride on rough, technical terrain. It provides an extra layer of security against chain drops caused by high-impact vibrations.

For the best performance and chain security, you should pair this chainring with a 'clutch' type rear derailleur, such as a Shimano Shadow or SRAM Type 2. The clutch mechanism keeps the chain tensioned, which works in tandem with the narrow-wide teeth to prevent derailment.
