Improved cadence and efficiency: the Sub-Compact oval chainrings by absoluteBLACK


absoluteBLACK now provides oval gravel/road 110 mm 4-arm chainrings for Sub-Compact gradation (Super Compact), with which you can increase your climbing abilities and cadence. A higher cadence is crucial to reduce the perceived strain. With the 30-46 and 32-48 t chainrings, you can ride anywhere and master any climb. Even alpine terrain will no longer be as difficult as it was.
These special Super Compact chainrings are compatible with all Shimano 4-arm cranks with 110 mm bolt circle diameter and work with 10-, 11- and 12-speed drivetrains. 30 and 32 t chainrings allow you to ride uphill at your chosen speed, with improved cadence and efficiency.

Technology:


Function
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.

Advantages of Oval Chainrings
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.

Ich finde die Teile super. Konnte sonst nichts finden mit 46/30 für die Ultegra-Kurbel und wenn man lange unterwegs ist/war braucht man sowas halt einfach!
Ich hatte genau 1x einen Chain-Drop auf ~14.000 km mit diesen Blättern und das war ganz am Anfang von mein Mechaniker dann nochmal etwas nachjustiert hat.

Einzig die komplizierte Lieferung ist ein echter negativ Punkt.

Auffällig ist das ich mit diesem Blättern deutlich weniger Knieprobleme habe als mit dem anderen Rad. Ob es natürlich an der Ovalität oder am Rad selbst liegt - schwer zu sagen.
Wer aber Schmerzen hat für den wäre es einen Versuch Wert!

P.s. Noch besser wäre wenn sie 46/28 anbieten würden.

Klasse! Jetzt komme ich auch mit meiner Kondition wieder gut lange Berge und Pässe hoch. 46/30 auf der Ultegra Kurbel. Sieht seltsam aus, aber ich finde es fährt sich richtig gut. Und bis 50 lohnt sich auch noch das reintreten :-)
