Product Description

Q-Rings boost your performance by varying drivetrain resistance during pedalling in line with your legs natural strengths and weakness. They make better use of the strongest muscle groups (increasing positive work) and compensate for the weaker zones in the pedalling stroke (reducing negative work). A Q-Ring gives a silky-smooth “perfect spin” by smoothening out torque variations and making better use of your strongest muscles.
Professionally, athletes who have chosen to ride them have put to rest any doubts about their performance by winning two grand tours, more than 25 Ironman races and over 20 UCI elite Road, MTB and CX world champion titles.

OCP (Optimum Chainring Position)
You can micro adjust the position of your Q-Rings to suit your riding style. Q-Rings use your leg muscles at a different rate than round rings, thereby changing your intramuscular coordination of motor units. Thanks to the OCP of the Q-Ring, you will find your best position seeking both comfort and efficiency.

I am thrilled with this size - but mounting is not without
Bin begeistert mit dieser Größe - jedoch Montage nicht ohne
Translated from German To the original

Had previously 50 teeth oval of rotor. Final speed was missing but a lot. The 53 teeth can be kicked easily and has enough reserves for top speed. For the assembly it should be noted that they do not fit in 3-fold. The eye here is the front derailleur. Had hoped to have the egg laying Wollmilchsau but now I can no longer switch to the small sheet, which went with Shimano sheet and 52 teeth without problems. Now it will show how my strength develops but large increases are not possible with the 39 KB.

Hatte zuvor 50 Zähne oval von Rotor. Endgeschwindigkeit fehlte aber doch einiges. Man kann die 53 Zähne problemlos treten und hat für Top-Speed immer genügend Reserven. Zur Montage sei angemerkt, das sie nicht bei 3-fach passen. Das Nadelöhr ist hier der Umwerfer. Hatte gehofft nun die eierlegende Wollmilchsau zu haben aber nun kann ich nicht mehr auf das kleine Blatt schalten, was mit Shimano Blatt und 52 Zähnen problemlos ging. Jetzt wird sich zeigen wie sich meine Kraft entwickelt aber große Anstiege sind mit dem 39 KB nicht möglich.
