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.
