New! The HubDoctor® Pro FULL HYBRID CERAMIC Ball Bearing Conversion Kit for Mavic® Freehubs ~ MTB and Road Note: For 2013 and newer see our listing for 2013 and up HubDoctor Pro kit. The 2013 model year uses a 9mm drive side axle and a silver outer bearing retainer cap. Please note: Does not fit the aluminum ITS-4 freehub. Get rid of the plastic bushing once and for all! Runs quieter too! Fits seamlessly into your hub, no special spacers required; looks identical from the outside. (The freehub bearings only spin when you are coasting). 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. The New HubDoctor® PRO kit features a dual sealed Hybrid Ceramic ball bearing with a full complement of 56 Si3N4 balls. ****The ultimate upgrade for Mavic® MTB or Road wheels using the FTS-L and FTS-X freehubs! Weighs only 12 grams!**** Fits Mavic® ROAD and MTB wheels with plastic inner bushing: Ksyrium, Aksium, Cosmic, Helium, Crossmax SL-Enduro-XL- SLR-ST-29-SX-UB, Deetraks, Deemax, Crossland, Crossland, Crosstrail, Crossride UB, R-SYS, Cosmic Carbon SL, Comet Route, Speedcity with FTS-L and FTS-X hubs (42.50mm or 1.67" long), 2001 to 2012. If you have a plastic bushing in the freehub this kit will fit. Wheels made after 2001 with magnetic freehub bodies are included in this group. Kit contents: inner and outer ceramic ball bearing (Si3N4), 6061-T6 aluminum freehub adapter, 1 outer seals, 1 bearing spacer, 1 sanding tool and sand paper, detailed instructions to walk you through installation. Please note: A new seal has been designed for 09 Crossmax SLR, ST, 29SS, R-SYS and others using this style design. From the non-drive side of the hub you will see a "keyhole" design where the spoke ends fits into. The external lip seal can be removed in these applications. The bottom line is that the kit will fit any of the Mavic freehubs using the plastic bushing and two pawl design. 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. This kit does not contain the freehub body or assembly, but is shown for demonstration purposes only.

What our customers are saying: Silenced my screaming freewheel! Thank you hubdoctor. Speedy delivery too!Comes with great documentation. Fixed my wheel for a fraction of the cost!! A++Fast shipment, very good documentation, in one word excellent ! These things really work ... a lifesaver for your wheel set... First Class ! Good instructions; Really Very Impressed; Came in 3 days, FANTASTIC Great item, fantastic seller. Hub just like new now. Thanks! Does your rear hub make a loud howl while coasting? Is the rear hub binding and turning in to a fixed gear? Grab the cassette and check side to side play. If it's more than two sprocket thicknesses and your freehub howls then your hub bushing is worn out! No Worries! The new HubDoctor® inner bushing replacement kit will fix your hub for a fraction of the cost of a new one! The Mavic® Crossmax freehub .000 standard sized bushing is for hubs with little or no measurable wear between the inner and outer axle surfaces. The HubDoctor new inner bushings are manufactured out of state of the art plastic and are tested and proven to last up to 2 times longer than the original bushing. (PV9700 rated). Now with 10% longer length and 50% thicker flange, fits perfectly and is twice as dense as the competition and much stiffer. Compared to plain clear Nylon, this material is stronger; lower friction coefficient or friction .1%; more heat and wear resistant, and will not absorb water. Nylon can absorb up to 13% compared to 0.3% for our bushing. And our bushing is made completely round on the flange so it fits just like the original part! This kit also includes an abec7 sealed outer bearing. For Mavic road and mtb wheels only: Ksyrium, Aksium, Cosmic, Helium, Crossmax SL-Enduro-XL- SLR-ST-29-SX-UB, Deetraks, Deemax, Crossland, Crossland, Crosstrail, Crossride UB, R-SYS, Cosmic Carbon SL, Comet Route, Speedcity with FTS-L and FTS-X hubs, 2001 to 2013. How to determine what size replacement bushing to purchase: To see which bushing size to purchase, standard or .003 oversized, take the freehub off the rear wheel and measure the hub surface next to the rubber seal which is all the way inside the hub. A digital caliper or 2" micrometer works best. If your hub measures .985-.984" order the standard size. If your hub measures, 983-.980 the .003 oversized bushing fits best. What if I’m unsure of the measurement? I suggest purchasing our kit that contains both the standard and oversized bushing to see which bushing fits best. Start with installing the standard bushing first and go to the .003 in needed. What if my bushing measurements don’t fit this range? Check my listing for the new HD Pro kit. (The hub picture on the right in the listing shows a case of extreme wear.) If your hub has extreme wear, in order to save the hub, and avoid the cost of a new one, its best to purchase our HD Pro Kit.Shipping is free in the USA! We ship Daily! Please Note: This kit does not contain the freehub body or assembly, but is shown for demonstration purposes only.
