absoluteBLACK Oval Road 110/4 Chainring for Sub-Compact

The absoluteBLACK Oval Road 110/4 Sub-Compact chainring for Shimano 4-arm cranks with a 110 mm bolt circle diameter

This oval 2-speed chainring by absoluteBLACK allows you to ride your Shimano road bike crank with Sub-Compact or Super-Compact gradation. This has the advantage of a very small gear ratio and thus proves to be enormously helpful on steep climbs. The chainring fits Shimano cranks with four asymmetrically arranged arms and 110 mm bolt circle diameter such as Dura-Ace R9100, Ultegra R8000, 105 R7000, but also Dura-Ace 9000 and other older models. It is made of premium quality aluminium and is characterised by long durability. Thanks to the oval shape, you optimise your pedalling movement, reduce the strain on your knees and move forward faster.

Note from the manufacturer:

These chainrings are not compatible with power meters that have a circular spider (e.g. SRAM QUARQ, Power2Max).
These chainrings are not compatible with SRAM Yaw front derailleurs.
Combinations other than those mentioned above are not possible. The small chainrings are supplied with screws, which are absolutely necessary for assembly.

Features:

• Sub-Compact gradation for easier climbing on steep, long climbs
• higher cadence and more efficiency on the mountain even without a larger cassette
• oval shape for improved traction and performance uphill
• 46/11 or 48/11 as the largest gear ratio is sufficient for flats
• faster, looser riding with a natural pedalling motion with reduced strain on the knees
• ovality and timing (108 - 110.5°) matched to chainring size (TDC technology, Top Dead Center)
• durable construction, CNC-machined
• anodised
• premium quality
• designed in Great Britain, manufactured in Poland

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.
