Campagnolo HB-HY100 Nirosta CULT Ceramic Bearings - Upgrade / Repair Kit for Record Hubs

The Campagnolo upgrade / repair kit consists of 2 CULT bearings and is suitable for Record hubs with 17 mm oversize axle, e.g Campagnolo Zonda, Bullet, Bora or Hyperon as well as Fulcrum Racing 3, Red Wind or Racing Zero wheels.

CULT™ is the combination of the highest quality ceramic ball bearings available on the market and races made of Cronitect® chromium stainless steel, i.e. the technological wonder made by the German company Schaeffler.

Ceramic ball bearings make it possible to reduce friction to the minimum and maintain consistent performance over time; bearing races made of Cronitect® with thermochemical surface treatment make the sliding surface of the bearings extremely hard and resistant to wear.

But that's not all. Friction of the wheel and crankset is extremely reduced thanks to the minimal lubrication system required by CULT™: only a thin film of oil in the place of the grease traditionally used.



The results from the Campy Tech Lab™

• 9 times smoother than the standard solutions
• Zero wear on bearings and balls
• riction coefficient: the lowest in the world of cranksets thanks to lubrication with oil instead of grease
• 3.5 watts more power at each pedal stroke, increasing along with the increase in speed
