Why choose absoluteBLACK?

• Very light weight compared to other chainrings on the market
• Striking design and color selection!
• Narrow/wide tooth profile, no chain guide required for use
• Special 3D tooth profile ensures good self-cleaning and makes the sprocket quiet when in contact with the chain
• Made from a single piece of lightweight 7075 aluminum
• Type II anodization used in the finishing of the gears protects the material from oxidation and keeps it looking fresh for longer

Specifications:

• *Oval cog
• Asymmetrical 4-bolt mounting
• 110/4BCD
• Only compatible with Sram APEX 1 cranks with asymmetrical bolt pattern and 110mm spacing
• Use the original bolts from the crank to attach the sprocket
• Not suitable for use with Shimano HG+ and Sram Flat Top chains

*Main benefits of oval chainrings:

1. Pedaling efficiency increases by minimizing the “dead zone” – since human muscles are unable to maintain100% consistent power output in the pedal cycle, the oval chainring amplifies the part where the power output is greatest and minimizes the sector where there is practically no output.
   • For example, an oval 36T gear behaves like a 34T round gear in the “dead zone” and like a 36T round gear in the effective sector. This effect allows you to quickly overcome the “dead zone” with less energy expenditure and maintain a constant flow of energy into forward motion.
2. The pedaling frequency (cadence) increases and the work of the legs becomes smoother – the oval inspires more use of the “pull-push” technique
3. Smoother pedaling helps save muscles, recover faster and reduces stress on the knees
4. Climbing steep hills becomes easier because, thanks to more consistent power output, the rear wheel doesn’t spin out as easily (we tried it – it’s actually quite difficult to achieve!)
5. The oval sprocket helps you learn the correct pedaling technique, so if you go back to using a round chainring in the future, your pedaling technique will be smoother than it was before you switched to the oval chainring.

We encourage anyone who experiences knee pain when cycling or who wants to improve their pedaling technique to try oval chainrings. There is no need to worry that using an oval chainring will mean having to “relearn how to ride a bike” – quite the opposite, in fact – pedaling with an oval chainring feels “rounder” than with a round chainring!
