Included with your replacement kit are step-by-step installation instructions, with photos, that walk you through every step, so it makes it easy to service your own freehub! 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.
