The Classified Powershift Hub contains a two-speed shifting mechanism, but also contains bearings, just like any other hub. These bearings ensure that your wheels turn smoothly and you can enjoy your ride without any noise or lost watts.
Depending on the conditions you ride in, the amount of kilometers you ride, and adherence to the maintenance guidelines, your hub bearings will have to be replaced at some point in time. This is generally every 2 years, depending on the use and adherence to recommended maintenance of the hub it can be shorter or longer.
Here's a few checks for you to perform to find out when your Powershift Hub needs a service:
Before you check: place your bike in a bikestand, or ask someone to hold up the bike for you. Make sure the thru axle is fully tightened to 15 Nm (this is handtight).
- Listen: Rotate the wheel. In a smooth running hub you will slightly hear the bearings rotate. Worn out bearings make a grinding noise.
- Feel: Rotate the wheel and place your hand on the thru axle. If the bearings are worn out, you will feel vibrations in your frame.
- Look: Check if the wheel has play by shaking it a bit from left to right. You don't have to apply any force to do this. If you can move the wheel from left to right while the thru axle is fully tightened, it is time to send in your hub for service.
In the video below, we show you the difference between a smooth running hub, and a hub with worn out bearings:
If you have any doubts about the condition of your Powershift Hub, we advise you to consult your local bikeshop. They are best placed to do the diagnostics for you. The lifespan of our bearings is comparable with the lifespan of other bicyle wheel bearings.
