Absoluteblack Oval Road 110/4 Chainring for FSA ABS

Product Description The cranks with 110 mm bolt circle diameter and four or five bolts This oval 2-speed chainring by absoluteBLACK was developed for FSA road bike cranks with asymmetric bolt spacing (ABS). It fits both 4-bolt and 5-bolt cranks, as they are identical except for the fifth, hidden bolt, which is not actually required. The chainring is made of premium quality aluminium and is designed for smooth shifting. Thanks to the oval shape, you optimise your pedalling movement, reduce the strain on your knees and move forward faster.

For the SL-K crank, continue to use the original FSA bolts and covers. The chainrings are not compatible with K-Force cranks as there are no matching bolt covers. Combinations other than those listed above are also possible, but these slow down the shifting process and require further adjustments to the front derailleur. Please note the maximum permissible difference of 16 teeth.

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.
