DT Swiss 350 Classic Road Center Lock Disc Rear Hub

The 350 Classic Center Lock Disc rear hub by DT Swiss for road wheels

This 350 Road rear hub from DT Swiss is designed for J-bend spokes and a center lock brake rotor. Its core is a resilient freehub with Ratchet 36 System and precision star ratchets. Thanks to the no-tool concept, the hub can be easily maintained without the use of tools. The end caps are shaped in such a way that uncomplicated and, above all, quick disassembly of the hub is possible. This is an advantage especially during races, but easy wheel removal is also an asset if you have a second wheelset that you use depending on the course or conditions. The sturdy aluminium hub body ensures a long service life, as do the steel bearings. The bearing play has been minimised and optimised. This is made possible by preloading the bearings before the hub is not clamped in the frame. Once fastened with the thru-axle, the preload is released and the bearings are maximally slidable. Thanks to the precision seals, they are also excellently protected against moisture and dirt.
