Campagnolo Zonda Spoke Replacement
Hello All,
despite having a reasonably good bike my maintenance knowledge for my bike is unbelievably poor. I basically take my bike into the shop for ANYTHING however I'm getting to the stage where i'm sick of this now.
SO my issue lies with my Campagnolo Zonda G3 wheels. A couple of weeks ago after taking my rear derailleur to a cheap bike shop to get it tuned up they did a crappy job and it blew out and into my wheels stopping me dead in my tracks!
The rear derailleur was stopped naturally by a spoke which has now bent slightly. I'm looking to replace the spoke however I need some help in doing this (in very basic terms). I've been watching some videos online but none specifically target my wheels.
The questions I have are...
Is the spoke Nipple Tool used to remove the nipples specific to my wheelset? to campagnolo? or a completely generic tool?
Page 17 of the campy site states use of a T-07 Tool
http://www.campagnolo.com/repository/do ... -12-10.pdf
Do i have to use that one tool? or are there other tools?
Do i need to go in from the rim? I only ask this as my wheelset doesn't seem to have that option. There seems to be no rim tape covering holes where you can access nipples from , rather a hard plastic casing just like the rest of the rim where the inner tube lies. (use final link)
Also how do you know when its been tightened enough? Within the video below they use some sort of device which measures how far away the rim is and therefore can tell if the nipple needs tightening and therefore aligning the rim better. What is this device? is it necessary? i bet its bloody expensive!!?!?!

should the hub have an external cover on it so where the spokes are lying against the hub, is covered up?
Going to page 100-101 of this shows the other side of the hub but it appears the other side does not have a cover

AND FINALLY... is it possible to straighten a spoke out? or should it just be replaced?
Apologies for the incredible long winded post but you can tell how much this stuff bothers me (and why I haven't tried to tackle it myself yet)
I bow to all of your amazing wisdom.

You know, there are some Campag jobs that kind of cry out 'Campagnolo Service Centre'. Even getting hold of a G3 spoke might be a job and a half, but I am sure you knew that before buying a set of factory built wheels.0

FYI, you can replace Zonda spokes with generic straight pull spokes that can be obtained at most well stocked bike shops. The length of the drive side spoke for 2010 era wheels is 280mm (11"). Best to bring in your old spoke though for an exact fit.
Be careful to not push the nipple into the rim when replacing the spoke. I was not able to fish it out using a magnet (ala the Campy Youtube video) and ended up drilling a hole in the rim to insert a new one.

If the spoke is bent only slightly and the wheel runs true , leave it that way.DW01 wrote:The rear derailleur was stopped naturally by a spoke which has now bent slightly.

Stainless steel is pretty ductile and the spoke is unlikely to break.0 -
actually it can break. I get wheels [*]back for a spoke replacement. In every one I have found evidence of mech in the wheel. gouging of a spoke even a little bit weakens a spoke. If one goes in the butted section you know it has been damaged.
spoke replacement on a zonda is a job for a good shop. It just has to be someone who know what they are doing. Velotech is the main service centre and so are chickens cycles. Some shops will be able to do it as well but it will be fiddley. It is a campagnolo wheel. how the hell they do this in the factory is beyond me, they are all built by hand.http://www.thecycleclinic.co.uk -wheel building and other stuff.0 -

They use the magnetic field of the Earth to keep the nipples in place...
