Absoluteblack oval road chainring for 110 5 bcd

Product Description The absoluteBLACK Oval Road 110/5 chainring for 5-arm cranks with 110 mm bolt circle diameter This oval 2-speed chainring by absoluteBLACK was developed for five-arm Shimano road bike cranks with 110 mm bolt circle diameter. These include Dura-Ace 7950, Ultegra 6750, 105 5750 and many more. The chainring is designed for super-fast and smooth shifting. It is made of premium quality aluminium and is characterised by particular rigidity. Thanks to the oval shape, you optimise your pedalling movement, reduce the strain on your knees and move forward faster.

Long bolts are required for the outer chainring. If you are only replacing the small chainring, continue to use the original bolts.

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.
