absoluteBLACK Oval 1X Chainring for Shimano XT M8000 / SLX M7000 / HG+ 12-speed

The absoluteBLACK Oval 1X chainring for Shimano M8000 and M7000 cranks and HG+ 12-speed chains

This oval 1x chainring by absoluteBLACK is compatible with Shimano XT and SLX MTB cranks M8000 and M7000, respectively, which have an asymmetric bolt circle diameter of 96 mm. It was specially developed for Shimano 12-speed chains, namely Hyperglide+ chains, and cannot be used with other chains. I also use it for the Deore M6000, M5100, M4100 and MT700 cranks. The chainring is made of premium quality aluminium and has a Narrow-Wide tooth profile that counteracts 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.
