Subject: Powertap on Mavic Carbone SL
I am thinking to mount the Powertap on my actual Mavic rear wheel but it seems that it would not be so easy for my LBS.
Anybody has this solution already? I would appreciate any quick review on that.

I really don't think you can do that. The rims for the factory Carbone with PowerTap is different than the standard Carbones; the fairing is different to allow the spokes to go through without tearing the carbon. Your standard rims will have a problem with this; the spokes will slowly but surely tear through the carbon fairing if you rebuild them with a PowerTap hub... Sorry for the bad news...

That's a very bad news if confirmed by my LBS...are you 100% sure? because it's a 20 spokes rim and the hub from Saris can be ordered with 20 holes...

I have another set of wheels, the Fulcrum Racing 3: is it possible on those?

thanks a lot for your comments!

Unfortunately, I am sure... the problem is not the number of spokes, but the lacing of them. The rear wheel has 2x on the drive side and radial lacing on non-drive side. For PowerTap, you need to have 2x on both drive and non-drive side. This has to do with how you measure the power, non-drive effectively becomes the drive side for the power measurement.

I would not recommend trying to relace a Fulcrum 3 to a PowerTap. A Mavic CXP33 for example is a very inexpensive rim (about $50-60) and spokes are not expensive at all... you could probably get your LBS to build you a PT wheel for about $100 (or less).

ok, I am not an expert on bikes so I trust you and I ask now: if I build that kind of inexpensive wheel, how should I go to racing? with this cheap wheel? or without the powertap and a good wheel???
Zipp404 is very expensive but the best solution for both training and racing....I would not go for a cheap one, don't you think?

Race on an inexpensive training wheel with a PT and a disc cover.
