Product details


KCNC Rear Derailleur Cage System for Shimano Ultegra 8000 / Dura Ace 9100 | 12 + 16 teeth ceramic

This Jockey Wheel System from KCNC is the logical consequence of friction minimization. Due to the large rear derailleur wheels with 12 teeth at the top and 16 teeth at the bottom, the looping radii of the chain are clearly minimized, which results in less friction.
In addition, the larger derailleur rollers, which are provided with smooth-running ceramic bearings, a longer life than other commercially available systems. Thanks to the narrow-wide profile of the teeth, your chain stays exactly where it belongs in any situation, making the Jockey Wheel system compatible
with single -speed drives.
The bearing cage is made of a lightweight and torsion-resistant 7075 aluminum alloy, so that the forces can be better distributed and recorded and your derailleur works perfectly even in the most adverse conditions.

Note: When traveling, please remember to dismantle the complete rear derailleur, as few bicycle transport bags offer enough space for the Jockey Wheel System!
