Don't replace your worn out hub (see last picture) - rebuild it - with HubDoctor® PRO! Convert your Mavic® Shimano or Campy Freehub to a full CERAMIC ball bearing system. Please note the photos of both of these hub types in pictures. The freehub is not included; this kit upgrades your freehub whether it is a Campy or Shimano type.

What our customers are saying about our HubDoctor® Pro Kit: PERFECT Solution, PERFECT fit, GREAT engineering, Superb Value, A+++++Buyer. This is how the hub should have been designed! Easy install, great instructions. Great Product, Better Than The OEM Set-Up, Worth Every Penny! Awesome product. Installed within minutes. Works great; saved a bunch of $$. Easy to install. High quality product. What else can I say? Thanks HubDoctor! 5 star product. After install; it is flying!! Should had 1 for ur self!! Just serviced after 2500 miles mostly mud and snow! Perfect! The outer bearing is a super smooth running Si3N4 ceramic ABEC 7 sealed ball bearing. The inner bearing spacer is included. A special light contact outer lip seal keeps out dirt and water. An Extra adapter seal is included in the kit. If you have a worn out hub journal, (see last picture), our new The HubDoctor® Pro kit will save you the cost of replacing the main hub since the new inner bearing sits behind the standard bushing journal on an unworn surface! Did you know the Mavic® freehub body shell is made of hardened steel and is practically indestructible! What wears out is the bushing and then you have to replace the entire hub and you’re stuck with an expensive paperweight! The new The HubDoctor® Pro Ball Bearing kit will fix and upgrade your wheel set for less than the cost of a new freehub! And with this new hybrid ball bearing kit you can eliminate replacing the bushings and a source of wear on your hub. Installation is similar to tapping or pressing in a headset and can be done in 30 minutes. Included with your kit are step-by-step installation instructions that walk you through every step, so it makes it easy to service your own freehub! Shipping is free in the USA! We ship World Wide! We ship Daily! Please Note: Photo 5 shows the bearing with the outer seal removed for illustration purposes only.
