absoluteBLACK Oval Boost Chainring for SRAM Direct Mount 3 mm offset
The absoluteBLACK Oval Boost chainring for SRAM Direct Mount with 3 mm offset
This oval 1-speed chainring by absoluteBLACK for SRAM MTB cranks with Direct Mount and MTB cranks with a removable spider features a 3 mm offset. It is therefore compatible with Boost bikes with 52 mm chainline and an over locknut dimension of 148 mm. It can also be used on Super Boost Plus bikes with a chainline of 56.5 mm and an over locknut dimension of 157 mm. Use it for newer and older SRAM cranks with a GXP, long BB30 or DUB axle, for various Truvativ models and Cane Creek eeWings. 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 ChainringsOval 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.
