Play in Bora Ultra rear hub- help please

[tbike4]

This is a Bora Ultra rim brake wheel from what year I do not know. It has some minimal side to side play. I looked at the hub and it is a foreign object to me. I have adjusted my share of non Campaq hubs over the years. Eazy peezy.

I did not find the help I need in a Google search. Do I need to remove the cassette? I think I would.

Have you seen these diagrams of Campi hubs?

If you think other hubs are easy, then you should be able to do the Campy hubs in your sleep. Not only do you not have to remove the cassette, you don't even have to remove the wheel from the frame (in fact, it is better to adjust the bearings with the wheel in the frame and QR tightened).

On the left side of each wheel (front and rear) you'll find what looks like a split collar tightened by a screw. That split collar is the threaded bearing pre-load adjuster. Loosen the screw on the collar, then rotate the collar CW to the tighten the bearings or CCW to loosen the bearings. Tighten the bearings just enough to remove play. Then tighten the collar screw to lock the collar in place. It should just take a couple of minutes to adjust each hub.

Thank you. That does sound like it could be done while sleeping.

Good to know. I have a couple of the 2mm allens which feel like they might break if you twisted it too hard. If you wanted to adjust the hub on the bike it looks like maybe this Park tool in the photo would be nice to have.

Opinion?

If you dont already have them, ask Santa for a set of these. Best hex keys on the market and every bike tinkerer should have a set.

You don't need to Gorilla this wee set screw down. NO need for a T-handle Allen for these. If you kill a 2mm Allen tightening this wee bolt, it's too tight..

Thanks for info. I do have a ?? On the other side of the hub there is a nut that screws on reverse thread. I made it finger tight as it appears you would need the the correct size skinny cone wrench to go tighter. Am I correct?

I did remove the play in the hub and rode it a couple of miles.

I bought the sliding T handle Allen anyway to have it in the arsenal. It looks nice.
