Our Premium 1X 104 & 64bcd Oval traction chainrings are designed for any cranks that use 104bcd mounting interface. This is the most common mounting standard for Shimano and other 4 arm cranks.

It is ideal for 1x 9/10/11/12spd and Singlespeeds. Oval (elliptical) narrow wide chainring does not compromise the work of clutch mechanism in rear derailleur. It also does not require chain tensioner when using in singlespeed application. Riding out of saddle on the uphill will become more pleasant. These chainrings also help you to recover after knee injuries as pedaling becomes smoother and less exhausting. It is the most advanced oval chainring currently on the market.

The most advanced, Patent Pending narrow/wide tooth profile ever produced, guarantee minimum 12 months of excellent chain retention capabilities! We mean it. Always use a new chain with a new chainring.

Performance & Pedaling Efficiency

The oval design of this chainring improves power delivery by optimizing the pedal stroke. It reduces the dead spot during pedaling, allowing riders to generate smoother and more consistent power. This results in faster acceleration and easier climbing, especially when riding out of the saddle on steep terrain. The design also reduces strain on the knees and helps maintain rider endurance during long rides. Riders switching from traditional round chainrings often notice improved cadence stability and smoother pedaling without feeling the oval shape during normal riding.
