Absoluteblack oval road 1x aero chainring for sram direct mount

Product Description The absoluteBLACK Oval Road 1X Aero chainring for SRAM Force and Rival cranks with Direct Mount The oval, closed Aerodynamic 1x chainring by absoluteBLACK is ideal for triathlon, time trial and criterium use, where aerodynamics and increased performance are important. It fits SRAM 11-speed cranks like Force and Rival, in which the spider can be removed and replaced with a direct mount setup. Its particularly favourable aerodynamic properties are due to the grooves on its surface. These significantly reduce air resistance compared to a smooth surface, especially at the revolutions and speeds encountered in performance-oriented cycling. The chainring 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 are faster on the road.

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.
