Is the hype about the Marvic 2 piece Superlight wheels failing correct ?
Has anyone had first hand experience with this issue or is it all hearsay ?
Whats the best alternative wheel to suit the SS Model range ?
I don't know about hype. I know there are documented cases of the composite Marvic-Akront wheels cracking.
I don't know from first hand experience, only from pictures I've seen.
From those pictures, the point of failure occurs where the rivets attach the hoop to the spokes.
There was a theory surrounding those failures at one time concerning the different metals involved, moisture and electrolysis.
Simply put, electrolysis made one metal an anode and the other a cathode eroding one while expanding the other. A crack or several cracks would then result.
Thus, failing isn't exactly the description I'd use. I never heard of a catastrophic failure of one that caused a crash and/or injury. I'm not saying such a thing didn't happen, only that it wasn't among the descriptions I'd read of the wheels cracking at the rivets.
As for replacements, there are a few options if you want to call them that. I did some research on this forum as well as the "other" Ducati forum and found a thread regarding the weights of different wheel options.
According to that thread, the composite Marvic-Akronts were not that light. Light for the time maybe, but not light by today's standard.
In fact, from the weights posted in that thread, the Brembo wheels that replaced the composites the following year were around the same weight.
Also, according that that same thread, the later SSie wheels were actually the lightest option, save for going with a set of magnesium wheels or some of the more expensive alloy or carbon wheels.
Even then, the difference was not as great as you'd think between the tapered spoke Brembo wheels and the high dollar alloy wheels from Marchesini, OZ or Carozzeria.
I did not weigh all those wheels myself, but the member who started that thread actually did. Actually weighed them with a scale rather than gathering published weights from manufacturers.
I sincerely hope that is some useful, 3rd hand information. Search the forum, you may be able to find that thread and read it for yourself. I don't subscribe to continuing myth and legend when the truth can be easily found.......sean
