Description

Description

These Rotor Direct Mount Oval Sram GXP chainrings have been specifically developed for the Sram GXP or BB30 Direct Mount cranks.

The Idea behind Rotor
The thought behind the Rotor Q-Ring/QXL-Ring chainrings is a simple one: every pedal stroke encounters a dead point. This is where the cranks are perfectly vertical. You can't exert any meaningful power at that point, so you'll want to get past it as quickly as possible. Rotor Q-Rings/QXL-Rings have fewer teeth at this point, allowing you to get through it quicker. They then provide you with maximum gearing during the part of the pedal stroke where you can provide the most power. This theory helps you get through the dead spot quicker, meaning you loose less power when you try to reach your optimal power band. This increases your pedalling efficiency, and reduces the amount of lactic acid you produce as well as your fatigue levels.

The technology behind Rotor is all about efficiency. Rotor believes that their product might not necessarily be faster of themselves, but that they help you generate a more efficient pedalling motion, thus reducing the net time it takes you to cover a time trial for instance.

Various scientific studies have proven the positive effect of the Rotor Q-Rings/QXL-Rings by now. Maybe even better proof are the numerous victories achieved in the pro peloton using Rotor Q-Rings/QXL-Rings.

Pauvre dessin - va me bouffer ma chaîne ?

- Richard 9 October 2021

Aucun problème de pose, sauf 'offset' pas très précis (fallait rajouter une rondelle au guide de chaîne de mon Scott pour que ça ne frotte pas.). Plus sérieusement, beaucoup de bruit au pédalage avec une nouvelle chaîne 12v X01 (bien lubrifié au 'rock n Roll avant la pose), avec Sensation de résistance au pédalage. Il y a une problème d'usinage ou dessin du profilé longitudinal des dents. Je vais essayer un autre rando, mais si ça ne s'améliore, il va être retiré du vélo.

Pros & Cons

Bon conception générale
Relativement leger
Très solide
Sensation de résistance au pedalage
Très bruyant (dents mal calibré ?)

5 / 5

Prima tandwiel

- Erwin 6 August 2021

Zorgt dat je anders trapt ( voelt anders ) dat is even wennen. Maar verder super.

Pros & Cons

Geeft meer kracht als je de bult op gaat
Zorgt dat je soepeler trapt.
Moet je wel aan wennen trapt anders

Echte Spaanse top Engineering!!

- Daniel 18 July 2021

De chainring komt in een mooie verpakking. Afwerking van de chainring is top, het is mooi zwart geanodiseerd met de logo’s in het wit. Het is voor mij een enorme verbetering tov m’n standaard 32t rond chainring. Op vlakke stukken een flinke toename in snelheid, ik kan ook makkelijker en op constant tempo doortrappen. Met klimmetjes heb ik nog niet zoveel ervaring maar daar ga ik vandaag wel achterkomen als ik MTB Groesbeek gereden heb. Maar op mijn vorige hardtail had ik een Garbaruk oval en daar merkte ik wel een verbetering met klimmetjes (UHR) dus zal het met de Rotor ook zo zijn Dik tevreden met m’n aankoop en een aanrader!

Pros & Cons

Flinke verbetering tov standaard 32t rond
Kwaliteit chainring is top!
Licht in gewicht
Makkelijk te monteren
Mooie looks
Geen, voor mij alleen maar pluspunten
