Bora ultra 50
Moderator: robbosmans
Bora ultra 50 rear wheel feeling gritty,i have taken bearings out and cleaned and re greased,but still the same.
Wheels are 2 years old and only had summer use,is it possible the bearings will wear so quickly?

It’s possible that the bearings that are worn are the sealed bearings in the freehub. These freehub bearings are non-ceramic and they are the same bearings found in non-ultra wheels. Did you check these bearing when you had the freehub removed? If not then check it and then report back.

It depends on if you have the right tools. You will need a snap ring plier to remove a snap ring. As for knocking the bearings out I prefer to use the proper bearing puller rather than using a screwdriver. Lastly you will need a bearing press to press in the two bearings. There's a separate thread on the tools needed for the job. With the proper tools it's a five minute job. I invested in the tools because I intend to keep my Boras for a long time. You can also buy a new Campy freehub and save yourself the trouble. I don't know how much they cost but it can't be more than $100 USD.

For the best bearings you need these. NTN bearings are second to none. You will need two. These bearings come with dual seals but you can remove the inner seal (seal not exposed to the elements) for a further reduction in seal drag.

Instead of bearing press you just need a smaller socket with an extension to knock the outer bearing off from the inside, and then a bigger socket to push the new bearing in.
Removing the inner freehub body bearing is not very easy, because the snap ring does not have ”ears”. So using snap ring pliers is rather difficult. I have drilled a hole through the freehub body in the location where the snap ring is, so I can easily push the ring off from its groove.
But I’m pretty sure it’s just the outer bearing that is faulty...

You are right its just the outer bearing as i have just removed it,i am buying some pliers to remove the inner bearing so i can replace the 2 which i have ordered.eurperg wrote: ↑Sat Sep 29, 2018 6:21 amInstead of bearing press you just need a smaller socket with an extension to knock the outer bearing off from the inside, and then a bigger socket to push the new bearing in.
