Maintenance-free igus® bearings on SRAM dérailleurs

Mountain bike derailleurs are exposed to the highest loads. Whether mud, dust, water or a combination of all of these - the environmental influences on the world's trails are extreme. In addition, there are root carpets, blocked passages, berms and steep turns. And what would a really nice single trail be without airtime? Exactly: boring! So there are also plenty of jumps. When you press the gear lever, you naturally expect the chain to land in the right cassette sprocket as quickly as possible. This is exactly where the iglidur ® G plastic plain bearings from igus® come into play, because the rear derailleur has to move extremely precisely and quickly to the correct position in order to change gear. This is done by moving the guide roller of the mountain bike rear derailleur to the correct position using a parallelogram mechanism.

The plain bearings from igus® have a number of advantages over direct bearings in plastic, aluminium or brass bushings: they require no external lubrication and are resistant to dirt, sand, dust, oil and water, plus they are unbeatably light. In contrast to the old bushing solution, the igus® bearings enable high precision with extremely low friction, which makes them virtually indestructible when used on the rear derailleur. The economic efficiency is mainly determined by the long service life of the bearings, which can be calculated using our online tool. As the igus® bearings do not need to be lubricated, there is also no need for bearing maintenance, which is otherwise quite difficult at this point. And the bearings are of course absolutely rust-free. So you can shred through mud and sludge in the worst rain without having to worry about damaging the bearings on the rear derailleur. Here you can already see how practical our bearings are when they are used on the rear derailleur.
