Fulcrum Racing one free hub

I need to replace the bearings in the free hub as one has failed, I am told this is not possible and I have to buy a new free hub, cant see why I cannot just pull the bearings and get them matched , (as per posts from here 2009)
Is this possible still to save a few quid as a new hub is around 60 notes ?

It is possible, it is not easy... if the alternative is binning the freehub, give it a go, you will learn something in the process even if you failleft the forum March 20230

I am in the process of replacing bearings in a F 0 freehub, the bearing is a 6803.
the outer bearing will just tap out, the inner one is the issue, it appears to be held in by a circlip, which seems to be impossible to get at, decent skf bearings are a tenner each, plus the time spent doing it, 55 for new f/hub may not be such a bad idea and you get a new pawl spring.
the design is shitte, these bearings lasted about 300km and some rain.0 -
Thanks guys, bottom line, its knackered so nothing to loose !
I'm in the spanner game, so Ill give it a go0 -

You can get bearings that are better than the originals for about £1.20 each. Quite how you got them to last only 300km is anyones guess - I took about 11,000 miles to knacker one pair (and probably half that to knacker the outer bearing of another). 300km I just don't believe.
Apparently you can get pliers that will sort the circlip easily. I just drilled a hole in the side of the freehub and pushed the clip out with a jewellers screwdriver. It wasn't that hard. You may not need to bother anyway as the outer bearing usually goes first.
You can get a new pawl spring for £2.50 or five for less than a fiver.
Of course, you might be just looking for reasons to justify not bothering!

Believe what you want, tbh I reckon I got even less than 300km
One wet ride was all it took to lock that outer bearing solid.
...and NO! I def don't have the dosh to spend 55, I was looking at some skf bearings for 10 each, the 1.50 ones would be crap and just do the same as originals? or maybe not!0 -

If you can wreck a bearing in 300km, it won't matter whether you use £1.50 bearings, £10 skf ones or ex NASA bearings at £5000 a piece - they still won't last long.
Exactly what do you know about the £1.50 bearings? Have you tried them or are you guessing stuff? They are probably similar to the originals except that they are double sealed rather than single sealed. And it's the unsealed inner side which is where the corrosion comes from.
Either way, the £1.50 ones appear to work for me but, as I said, maybe none would work for you. I ride mine day in day out often in terrible conditions and they have never locked up. I cannot see how it would be physically possible to cause a bearing to lock up immediately after one wet ride unless it was actually faulty in the first place. I would be going back to the shop if that happened to me and expecting a replacement wheel.Faster than a tent.......0 -

Fine. I've told you the £1.50 bearings are better than the standard ones (and I've told you why), I've told you that, based on what you have said yourself, that your specific wheel is faulty rather than afflicted with a design flaw so really you should be going back to the shop and getting it replaced for nothing. If you'd rather spend £50 plus on a new freehub which, according to your own theory, will only last 300km rather than achieve the same result or better for either nothing at all or about £3 and an hour or so of work then be my guest. No skin off my nose! Faster than a tent.......0 -
So, looking good, whipped the bearings out, quick go with Mr Google reveals a guy not 5 minutes from my front door can supply the replacements needed to get the job done.
BOOM piece of cake, new free hub ...................................yea right !0 -
yep I replaced the bearings on my free hub a few months ago, its worth chucking a new pawl spring in there while you've got it off too, also to make your life easier when you get the new bearings put them in the fridge for a bit before fitting them, then just before fitting them use a hairdryer/heatgun to warm up the free hub body a bit, then they will drop right in with no effort0

ok ok ok! I hold my hands up, I was wrong!
I went on what I d seen with a cursory look at the inner bearing circlip, which looked like it had no access for pliers but the F0 has a normal clip that can be removed easily with some long nose at1s, im not sure a 1.50 bearing is as good as a skf or fag but I ll take your word on that.
the wheels where new but were hardly used in the first 8months, I-Ride refused to warranty the freehub, sighting the f/h bearing was a consumable, even advising me to spend an additional 100 + on a ceramic hub upgrade and of course a new f/h, for a tenner on new bearings it didn't seem like worth arguing with them and I only needed the outer one at the time.
I still say though, its a bad design, aside from the bearing seal, there is nothing to stop ingress of water etc and fulcrum removing the inner seal, just allows the grease to be pushed out easily.0 -

Have you been using GT85 or WD40 on your chain?
If you have then it is the quickest way to bugger up bearings, that came from the Horses mouth, Mr Campagnolo himself!0 -
that's interesting, I ve a set of F5s that go through outer f/h bearings and I have used, sparingly, to clean up chain after a wet ride, GT85 doh!0
