KCNC SH8000/9100 Jockey Wheel System | 12/16T Gold

Unleash the full potential of your Shimano drivetrain with the KCNC SH8000/9100 Oversized Jockey Wheel System. Engineered for cyclists who demand peak performance and a distinct competitive edge, this system is a game-changing upgrade for your transmission. It is meticulously designed to replace the standard pulley wheels and cage on your Shimano Dura-Ace or Ultegra rear derailleur, transforming its efficiency and aesthetic.

The core benefit of this system lies in its advanced oversized pulley design, which significantly reduces drivetrain friction. By creating a larger, smoother path for your chain, the system minimizes articulation and energy loss with every single pedal stroke. This translates directly into saved watts, allowing you to ride faster and longer with the same effort. Whether you´re attacking a climb, sprinting for the finish line, or maintaining a high pace on the flats, the reduced friction gives you a tangible performance advantage.

Experience a new level of shifting precision. The KCNC Jockey Wheel System ensures exceptionally crisp, fast, and reliable gear changes under any load. Each pulley is equipped with ultra-smooth, low-friction bearings that spin freely, contributing to the overall efficiency and providing a silent, fluid ride feel. The precisely machined teeth on both the upper and lower pulleys guide the chain with unerring accuracy, eliminating hesitation and ensuring you´re always in the right gear at the right moment. This upgrade not only enhances performance but also offers remarkable durability, ensuring your investment continues to pay dividends in speed and reliability season after season.

Beyond the pure performance gains, this system offers a stunning visual upgrade. The striking gold finish and meticulously crafted cage add a professional, custom aesthetic to your bicycle, setting it apart from the crowd. As with all KCNC components, this jockey wheel system is designed with a focus on minimizing weight without compromising strength, helping you shave precious grams from your high-performance build.

If you are a competitive racer, a dedicated enthusiast, or any cyclist looking to extract maximum efficiency from their drivetrain, the KCNC SH8000/9100 Jockey Wheel System is the ultimate transmission upgrade. Elevate your performance and redefine your ride.

Miquel

Is it compatible with Shimano Di2 8150 12 speed shifting?

Answer of Imlay

Hi there I don't think so. Just for 11S .

Answer of Nicola

I don´t know, I got it for 11 speed...check the length because what it depends on in my opinion is the size of the largest gear you have in the back. Short cage. Or long cage.

Alexandru

I need to replace a brocken Dura ace 9100 cage, and I need to know if this system is the equivalent of the SS shimano cage (max. capacity 30 teeth) or GS shimano cage (max. capacity 34 teeth - but works with 36 as well).

Answer of Aleandro

I used it with an 11-34 cassette and it worked perfectly. I think it could also be used with a 36 and perhaps even with a 40 gravel...

virgilio

does it come with CERAMIC BEARINGS?

Answer of angel

No, if there is any advantage, in this model it is given by the size of the rollers... If you want the advantages of ceramic bearings, you should go to other models.

Hello, can you tell me if this cage is compatible with a shimano ultegra 6800 11-speed electronic derailleur? I currently have an 11-28 cassette and I want to mount 11-32 thanks in advance

I mounted the component on an 11v mechanical ultegra gearbox. If the attack is the same I think it is compatible.

Pont

Hello Can you tell me if this cage is compatible with a dura ace 9100 11 speed derailleur and an 11-34 tooth cassette? Thanks in advance

Answer of Claudiu

I believe it is compatible. I use it with a 11-32 cassette and i don’t see why it should work with a 34 cog. There is plenty of space between the cog and pulley wheel

Answer of Francisco Mateo

I mount it on an ultegra R8050, with 11-34 and it´s perfect.
