absoluteBLACK Oval 1X Chainring for 104 BCD / Shimano HG+ 12-speed

The absoluteBLACK Oval 1X 104 BCD chainring for 4-arm cranks with 104 mm bolt circle diameter and Shimano HG+ 12-speed chains

This oval 1-speed chainring by absoluteBLACK is compatible with four-arm MTB cranks that have a bolt circle diameter of 104 mm. It was specially developed for Shimano 12-speed chains, namely Hyperglide+ chains, and cannot be used with other chains. Use it for cranks from Shimano, SRAM, Race Face, FSA or other manufacturers. The chainring is made of premium quality aluminium and features 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.
