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)

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.

Less than expected

These pulleys look nice, but have more drag than the standard pullies that came with my red derailleur. Did not install due to high level drag. For appearance only, not performance.

Bought these for replacements an XO rear der. Easy swap. Lighter. Shed mud and grease better. Something about the ride is noticeably smoother, perhaps the ceramic bearings.

Needed to replace my old pulley wheels and was curious to try a ceramic option. Really amazed at how smoothly they turn - almost like they are not there.

Comments about KCNC Bike KCNC Ceramic Derailleur Pulley Wheel:

I needed to replace some derailleur pulleys and saw these. Mostly I love the look of them and they are easy to clean when you get that mix of chain lube and dirt on them. Probably no better or worse than some other stuff on the market, but they look awesome and are strong and tough.
