Description

Description

The Rotor Aldhu chainrings + R9100 cover set is a good combination to smoothly connect your Rotor chainrings to the Shimano R9100 crankset. The Rotor Aldhu chainrings are equipped with an asymmetrical fit in a 110 mm stitch. The original Shimano chainrings are thickened at the connection and the Rotor covers are made to eliminate that difference. Do you have a Shimano R9100 crank set and would you like to drive with oval chainrings? Then this is the product you need!

Technology

The thoughts behind the Rotor Q-Ring chainring are clear: each pedal movement has a 'dead center'. This is the moment when your cranks sit vertically. At this point there is no possibility to keep pressure on your crank/pedals which makes you want to get beyond this point as fast as possible. Rotor Q-Rings have less teeth on its dead center which makes you go faster past this point. The next thing that happens is that you feel maximum resistance, at this point you can get maximum power out of your rotation. With this technology you will pass your dead center faster which ensures less power loss before you point of maximum power. This results in an efficient pedal movement, and less fatigue in your muscles.

The technology behind the rotor is characterized by efficiency. Rotor believes in fact that its products are initially not so much 'faster' but it's mostly the efficient pedal movement which improves the actual net time.

Several scientific studies have proven the positive effect of Rotor Q-Rings chainRings. Perhaps even the best proof is the many victories achieved in the pro peloton on Rotor Q-Rings / QXL-Rings.

Super aankoop!

- Eddy 7 April 2020

Na lang wikken en wegen toch de keuze gemaakt om in ieder geval te proberen te overstappen naar ovale kettingbladen. Online nodige min- en pluspunten voorbij zien komen, maar vanaf het eerste meteen tevreden. Voor mij voelde het eerste moment tijdens het fietsen alsof je een “hupje” meekrijgt in de omwenteling. Ook viel me op dat je met meer gemak een hogere cadans haalt zonder dat het onnatuurlijk voelt. Ik ben hartstikke tevreden en die bladen blijven erop. PS: meteen de fiets verder gepimt door de gouden KMX ketting via Mantel na te bestellen.

Pros & Cons

Afwerking
Ideaal dat het een setje is
Ziet er straks uit
Het is een beetje puzzelen met installeren
