absoluteBLACK Oval 1X CX Chainring for 110/4 BCD

The absoluteBLACK Oval 1X CX 110/4 chainring for 4-arm cranks with 110 mm bolt circle diameter in cyclocross use

This oval 1-speed chainring by absoluteBLACK was developed for four-arm Shimano cranks with 110 mm bolt circle diameter. These include Dura-Ace R9100 and 9000, Ultegra R8000 and 6800 and many more, with the exception of the GRX cranks. The chainring is perfect for cyclocross or gravel cycling thanks to its dirt-repellent properties. It is made of premium quality aluminium and features a Narrow-Wide tooth profile to counteract chain drop. Thanks to the oval shape, you optimise your pedalling movement, reduce the strain on your knees and move forward faster.

Technology:

Oval Chainrings
Oval chainrings follow the natural physiology of humans. They maximise pedalling power the moment it is developed and minimise resistance when it is not. As a result, oval chainrings allow the rider to pedal more smoothly and stay loose on the climb.
In fact, your pedal stroke will feel " rounder" with an oval chainring than with a round chainring.
Compared to round chainrings, oval chainrings address more muscle groups - but each of them to a lesser degree. The total load of pedalling is therefore distributed over a larger muscle mass and the knees are less strained.
This has three advantages: 1. The legs remain fresher and more relaxed. 2. You can go uphill faster. 3. Spreading the load over more muscles reduces the susceptibility to cramps, even with great effort. Ultimately this will increase your riding pleasure. For MTB applications, the rear wheel traction is increased on loose and slippery surfaces, allowing you to make better progress on demanding terrain.
