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

Product Information

There’s more potential for wear with a pawl system, as there are a small number of mating surfaces rather than the multiple intermeshing teeth of the ratchet. Thus if you keep the thing well lubricated, and the water out, the freehub should last almost indefinitely. 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) .

There’s a good chance that if you don’t regularly maintain your hubs, then everything inside will be pretty filthy. Going the other way if the stuff you use is too thick it won't keep the seal lips wetted (and they will then wear) and it may cause the pawls to be so sticky that they wont always engage simultaneously, which is very bad; it causes breakages to occur. For brake fittings, since you mentioned it, there are even products that don’t react negatively with the fluid or hose material or bladder/seal material within caliper or lever; SRAM offers a DOT grease to be used with its DOT-fluid based braking systems on the coupling nut.probably meant to justify a more expensive hub with an inner spacer in and a drive ring with a few more points. With my Shimano freehubs I just remove them from the hub, remove the rubber seal from the rear and squeeze grease into the recess behind the seal until it comes out of the other end of the freehub (the bearing cup), and clean out the purged crud before greasing the bearing cup. In the nastiest conditions we usually even have a strategy where Kate might be prepared to stop to re-lube mid-race. Also, simply wiping the chain off after a ride goes a long way and is probably not done enough by most folks. Although it’s one of the more fiddly bike maintenance tasks, it’s not beyond the capabilities of a home mechanic.

Often if you try and clean this area it just forces dirt into the gap and this means that noise-wise you can 'make things worse'. I agree, some really light oil might thin out the grease a little, assuming that high viscosity is the problem. If you use the right semifluid grease then it has all the advantages of oil (keeping the seal lips wetted etc) with none of the disadvantages (it doesn't leak out at anything like the same rate).DT Swiss freehubs are all now built on the ratchet system and come with between 18 and 54 points of engagement. If one of the pawls fails or doesn’t engage effectively, there’s a greater risk of damage to the freehub’s internals and the freehub failing. Anti-seize is great when combining two dissimilar metals because it acts as a barrier preventing chemical bonding (seizing) from occurring.
