Campy Proton hub flaw?

[Giorgio Cosentino]

My rear Campy Proton hub has had play in it since I purchased it. The
shop mechanic could not fix it either. I heard there are other people
who are also experiencing this. Is this a flaw of some sort, or is
there supposed to be this much play? Thanks.

I answer-"Since the Proton wheel hub is based on a Centaur hub, I don't see why
the 'play' cannot be adjusted out. Does the shop guy know how to do this?"

Hi Peter (or anyone else who can answer),

While we're on the subject of mid- to low-end Campag, I've put on my
winter wheels now (Veloce on MA3 32x3). I always have a slight amount of
wobble on the back hub. If it'd been Record (as my summer party wheels
are) I would've called this "cones too far apart" and adjusted the
bearing a bit. But IIRC this hub is cartridge everywhere, so different
rules apply here.

This looseness of hub flange relative to axle is not dangerous as such
but I wonder what the procedure is to get rid of it, just as a matter of
aesthetics.

I thought the Proton wheels came with top-of-the-line record hubs? I
had my bike built with Campy record---and now I learn that the hubs
are only low to medium grade? Do people swap out the hubs on these
wheels? The shop owner/mechanic was unable to get rid of the play in
the hub. I didn't want to do it myself because I was not familiar
with this design.

I answer-"You can try two 17mm wrenches and try to just tighten them and then
pretty damn tight via the skewers."

Giorgio,

The hubs are indeed Centaur, which perform alright but you cannot
upgrade them. I actually find adjusting them to be reasonably easy but
I have only had one pair (now sold). You should also know, that since
these wheels have a unique lacing pattern and the spokes are expensive
you get what you get and you cannot afford to change them. Worse, if
you wreck a rim, these are throw-away wheels. The rims are obscenely
expensive even wholesale. I know from first hand experience with a
front wheel In fact, if you need a front parts wheel, I will ship
you this one for the cost of shipping!

The qualety of Centauer hubs is very high, the diference between
Centaur and Chorus is the front axle: Centaur uses a hollow steel
axle, Chorus a hollow aluminum axle. Record ads a titanium pawl in the
rear vs steel and grease ports on bothe front and rear.
Appart form that the 3 hubs has different Quick Releases.

I answer-"well thiose hubs are almost identical to Record type hubs, just uses
a steel pawl carrier instead of a steel one and a plastic bearing adjuster.
'Record' level package wheels are Neutron, Nucleon...

Put the wheels in the frame, clamp them down like yer gonna ride. There is a
adjustment plate on each hub that loosens either with a 2.5mm allen wrench or a
phillips head screw driver. Loosen and then turn the plate a wee but with a
wrench until the play is gone, retighten the set screw."

I answer-"Sorry, not true. Centaur front hubs are identical to Chorus and
Record except with a plastic vs aluminum plate for adjustment and plastic end
on the skewer. All three have aluminum axles and the same cones/bearings."

Brutal, not very Campagnolo-esque, but it works, thank you Peter
