Item number: 66363

absoluteBLACK Oval 1X Gravel Chainring for 110/5 BCD - grey/50

The absoluteBLACK Oval 1X Gravel 110/5 chainring for 5-arm cranks with 110 mm bolt circle diameter

This oval 1-speed chainring by absoluteBLACK has an offset of 1.5 mm and was developed for five-arm Shimano cranks with 110 mm bolt circle diameter. These include Dura-Ace 7950, Ultegra 6750, 105 5750 and many more. The chainring is perfect for gravel use thanks to its offset and 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.
