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.

Had hem veel eerder moeten aanschaffen!

Ik rijdt hem op een Trek Stache. Dit is een 29+ bike die van nature al meer moeite kost om hem lekker op tempo te fietsen (door de grote banden). Van een standaard 30 blad naar een Oval 34 gegaan. Wat een enorm verschil. Het voelt inderdaad de eerste 2 km een beetje vreemd aan, lijkt alsof het doortrapt. Maar als je eenmaal bezig bent, trapt het veel lekkerder door. Ik merk het meeste verschil als je een heuvel/berg op gaat. Er is geen dood moment meer waar je altijd even overheen moet trappen. Nu is het een constant vloeiende beweging. Het is ook makkelijker om op een hoger tempo te rijden. Dit komt ook doordat het blad groter is geworden. Lang getwijfeld om het te doen, die twijfel was nergens voor nodig. Super blad!! Komt zeker ook op mijn ander fiets :-)

Pros

  • Geen "dood" moment
  • Minder weerstand bij heuvels/berg op
  • Vloeiende beweging tijdens fietsen
  • Vuil afvoer tijdens blubber ritten

Cons

  • Best aan de prijs
