    A top quality tool essential of you are serious about servicing your own hubs.

  12. A F –

    I used two of these, a Wheels Manufacturing Press-4, a 50mm hex socket (BGS 3450) and M10 Polyamide washers to change the hub bearings of a Zipp ZR1 rear hub.

    Removing the bearings with the adaptor and the socket as an extractor was very easy. The plastic washers helped protect the axle.

    For pressing the bearing back on the axle, the adaptor is about 5mm too short. I didn’t have an additional, shorter overaxle adaptor to extend it, e.g. the 7mm deep one from Wheels Manufacturing should work. So instead I had to give the adapter a bit of a reaming so that the axle could pass through. Once the hole was wide enough, pressing in the bearings was very easy as well.

    The Press-4 was just long enough, sometimes barely engaging the threads. Better get a press with a longer rod and a more standard thread, e.g. from Bearing Pro Tools.

Does this work for Zipp cognition V1 hubs ? TREVOR HALL asked on April 25, 2023

Hi Trevor, yes it will work. It's bearing size dependent not hub dependent. i.e. it will work for any 6903 bearing on any hub.
