absoluteBLACK Oval Road 110/5 BCD Chainring for SRAM

The absoluteBLACK Oval Road 110/5 chainring for SRAM cranks with 5-arms and 110 mm bolt circle diameter

This oval 2-speed chainring by absoluteBLACK was developed for five-arm SRAM road bike cranks with 110 mm bolt circle diameter, which have a chainring bolt concealed by the crank arm. These include Red, Force 22, Rival and a few others. 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.

Note from the manufacturer:

Continue to use all SRAM chainring bolts except for the hidden bolt. The outer chainring is supplied with a suitable bolt for this position. If you are only replacing the inner chainring, continue to use all the original bolts.

Features:

• oval shape for improved traction and performance uphill

• ovality and timing (108 - 109.5°) matched to chainring size (TDC technology, Top Dead Center)
• 15% less shifting operations needed
• 5 mm thick and 15% stiffer than comparable chainrings
• 6 shift ramps, 12 downshifting points and design with cutouts for fast, smooth shifting
• 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.
