KCNC Ceramic Derailleur Pulley Wheel

KCNC Ceramic Derailleur Pulley Wheel

KCNC pulleys are intentionally designed with an integral amount of "float," or lateral movement. This movement allows the pulley to settle into an optimum position under each cassette cog. The result is faster, smoother shifts and a quieter drivetrain. Each KCNC pulley wheel is equipped with a high quality hybrid ceramic cartridge bearing. The advantages of using a ceramic bearing in the rear derailleur's pulleys are the most dramatic of any other bicycle bearing system. This is due to the high speed at which the pulleys spin - often as high as 600 RPM. Each pulley is machined from light and strong 7075 aluminum and anodized, with laser cut logos.

  • Sold individually
  • 11T
  • 7075 anodized aluminum construction
  • 689 hybrid ceramic bearings
  • Weight: 8.5g
  • Compatible with all Campagnolo, SRAM (road and X0), and Shimano rear derailleurs.
    (Note: Campagnolo 10 speed derailleurs are equipped with 10 tooth pulleys, SRAM, Shimano, and 11 speed Campagnolo are equipped with 11 tooth pulleys)

Great Product
These are great. I had one pulley on my SRAM deraileur sieze up on me and decided to upgrade. I'm glad I did, despite the cost. Easy to install, really smooth, perfect shifting with these and the best thing is they don't seem to get a lot of dirt glued to them like the plastic ones and they are easy to clean.

PROS: Lightweight, Attractive Design, Durable, Easy To Install

BEST USES: Upgrade, Mountain Biking

looks great
The price is somewhat irrelevant when it comes to style! These pullys can set your bike appart from the norm, and are race ready in the same product.

Super easy installation, quality piece. Immediately noticed smoother shifting as well. Certainly a worthwhile upgrade over the stock jockey wheel.

Awesome!
These run SO smooth on my 2017 Rockhopper. Instantly noticeable feel when hand-spinning the crank. Highly recommended.

Love the bling!
Great addition to my bike bling! Could be my imagination, but the rear derailleur seems to spin better than with the stock plastic pulleys. Highly recommend the upgrade!

They work
They did not spin as freely out of the packaging, as videos had shown. I will check them next time I clean my chain.
