SHIMANO Special grease for pawl-type Freehub bodies 50 g,White

Product Information

Once you have a clear view on all of that you can fiddle around with various lubes, change your cleaning method etc.

Opportunities to extend a freehub to fit a wider cassette are more limited though, with only the Campagnolo N3W system providing an adaptor to allow this.There are many different standards used by the different drivetrain makers – that’s mainly Shimano, SRAM and Campagnolo – as well as different ones for mountain bike and road bike freehubs. Brucey wrote:It is important to distinguish between shimano style freehub bodies and the others, where the freewheel body rotates on the axle using its own set of bearings, which is what I presume you have.

A pawl freehub consists of sprung levers that mesh with a toothed drive. James Huang / Immediate Media Dumonde Tech PRO X freehub grease has been designed specifically for freehubs that require a lightweight grease that will stay in the moving parts and provide long term high level performance. Within each, there are lots of variations in how they’re engineered and there are some well-known specialist designs such as Chris King hubs.When you have the two ratchets together and facing each other, coat the teeth around the outer with grease and slide them onto the Thread Ring sitting on the axle. Then slide the freehub body onto the axle, replace then end cap and there you go: one serviced freehub. It wouldn't be a bad idea to test the impact of the freehub ratchet and pawl system of a bike and see if high-tech coatings could reduce any residual drag. So my opinions are based only really on what I’ve seen, and the conditions I find myself in. What works for me may not be as effective in a different environment, or a different application, so it’s important to really feel things out and keep an eye on how things seem to be working. Talking to an experienced mechanic in your home environment may give some insight into what works well locally for the application you require. Local bike shops are probably the greatest underutilized resources to really dial in your lube theory if you can find a good one. There are two types of springs currently in use; multiple small coil springs and single-circle clip springs. The former are found in older Hope and older Campagnolo hubs. The latter is used in newer hubs from Hope, Campagnolo and a host of other manufacturers.

Our Freehub Grease is Exclusively used by: Industry 9 “Legacy”, “Hydra” and “101” hubs and Stan’s NoTubes, Hermes Sport and Hawk Racing. so if the axle is loose the whole wheel slides side to side in the frame. Hammering the inner race each time. Affects shifting and brake rotor World Cup mechanic Brad Copeland took the time to go over nearly every moving and clamped piece of the bike, sharing his knowledge from working on Kate Courtney’s Scott bikes as well as his off-season work at a local California bike shop. Copeland has shared loads of info with us in various tech articles and in a podcast episode. This time we asked for a lot, and he delivered. So let’s learn about lubricants together. Chris King’s ratchet slides on angled splines in the hub rather than the straight in and out ones of DT Swiss’s hubs. The left side of the axle is fitted with a hex hole. Use a 6mm hex wrench to hold the axle. Loosen the axle nut on the right side using a 17mm wrench.

Some greases really are special. But in other cases the grease doesn't really matter. Since so many companies just say to use their approved grease, it can be hard to tell apart which applications are really special and which ones don't really matter. I'm pretty certain this is one of the most neglected areas of a race bike. It surely does deserve some looking into.

Hi BobDopolina, ahh, so there's not one grease that does it all, in this area ... lets say sealed bearing hubs, sealed bearing freehubs with or without a needle bearing, and quiet or louder ratchet sound is ok (such as the Novatec hubs/freehubs that you sell) ...Be sure to grease this splined interface before reassembling Dave Caudery Servicing Campagnolo freehubs It will even reduce friction on Campa's much touted CULT bearings which are quieted down by a parafin based oil. A neat solution but it's actually adding friction..... Unfortunately it's not very clear which grease and additives is best, because bicycles are different from lots of other applications in that speeds are quite low, and temperatures not too high. Durability is likely to be important. Most rear hubs allow the freehub body to be removed. The body can then be flushed with solvent for cleaning, dried, lubricated with oil, and then reinstalled. Much of the process is similar to a hub overhaul. To service the freehub, begin by removing rear cogs. On a freehub, the mechanism is pretty well-sealed and greased from the factory. However, they are pretty easy to disassemble in most cases.
