Description

ROTOR chainring Q-Rings XC3 2x conversion kit LK64 Interior

This variant of the Rotor Q-Rings allows classic 3-speed MTB cranks with 104/64 mm bolt circle on a 2-fold configuration rebuild. Without having to invest in a new crank so you can take advantage of a 2-fold crank together with the advantages to enjoy, providing them with the Q-Rings! The small chainring, which is offered here must be mounted on the inner position of the 3-crank so that a 2-fold yields drive together with the large sheet.

The oval shape of the Q-Rings chainrings serves the best use of leg muscles, thereby increasing their own performance! The theory behind this is based the fact that the leg muscles of man is primarily aimed to straighten the leg while angling the leg is necessary only rarely and without much effort. The corresponding muscle groups are therefore less pronounced so naturally that even through hard training the performance of the different muscle groups can not be equalized to each other. From this difference, therefore, is always followed with round chainrings a non-circular passage and a significantly faster fatigue the pulling muscles while pedaling. Rotor Q-Rings set at this point and strain due to its oval shape more the pushing muscles, while reducing the pulling any muscles. This concept increased by making better use of anatomical thus both the sprint and endurance performance!
The chainrings are essentially for a plurality of holes for the chain ring bolts, which allow fine abgetuft adjust the alignment of the sheets on your own preference!

The particular shape of the chainrings allows you neatly executed switching ramps still clean shifts.
