I have Neutron Ultras with 7,500 miles on them. Bullet proof. Had them serviced recently just because I thought It was a good idea. Ride them year around. Can't go wrong in my opinion.

Hi,

The old round hole one has been pulled many years ago already which is why they offer this kit with the new squared axle end and the new free hub.
This then replaces the old round axle and its free hub.
The old free hubs will fit on the new axle but not vice versa.



That's the spare part number for the kit:
The advantage of the old FH was that you could rebuild it completely whereas the new one won't give you access to the inner side's bearing (well it is not impossible but no shop I know of will actually to it) which nine out of ten will die first anyhow.

Either way, your FH can still be rebuild if it's the bearings that caught water. All it takes is pushing the alloy barrel to the side, push the top bearing out, remove the circlip that holds the inner bearing down and then pull or push that one out.
Then you put new bearings (2 x 6803 SKF with one rubber seal removed) in. In reverse order.
Pretty easy.

Ciao,

Hi,



That's excellent news. The old system without the holes was really disappointing. It had "Throw me in the bin because you won't be able to repair me" written all over.
Not Campa-like at all.
Glad they changed that.

Thx for the info.

Ciao,

I was talking about this rubber seal:
the original freehub didn't have that, I suspect (I could be wrong) that salty water messed things up inside the freehub.
The complete wheelset weighed 1651 gr (not the ultra model) so yeah zonda is lighter than the plain neutron

Just when I thought they were perfect, I'm pulling on this mornings group ride and, BANG! Broke a rear spoke At 155 pounds I'm not heavy and not all that powerful either. Bummer for sure. Off to the bike shop for a repair. Might be time for some new carbon clinchers. Any excuse is good

Yeah I agree, that's as good as reason as any. Go carbon.

agree, nothing ever goes wrong with a carbon wheel

One.

So let's just say I'm drivin' this buggy...
and if you fix your attitude you can ride along with me.

Actually, I prefer non carbon for my riding...but I always support massive expenditure of $$$ for equipment. How can it be wrong when it always feels so right?

Hi,



Of all wheels that's about the worst you can do.

Ciao,

I'm sure you're right. My local Campy Pro-shop fixed the Neutron rear for me and it's back on for another few thousand.
