Wjhat is the problem with Ambrosio wheels?(7 posts)

Wjhat is the problem with Ambrosio wheels?Velocipedio

I had a very slight crash yesterday, a fallover, in fact, and my rear wheel is COMPLETELY out of true -- out of whack is more like it. I'm going to take it to a wheelguru today to see if he can do anything about it.

What kills me is that this is the SECOND thime this has happened to me with Ambrosio Excellence rims. The other time was a fallover a month ago that completely trashed my front wheel.

What are these rims made of? Putty?

It's possible there is nothing wrong with the rims themselves, but the builder did not do a proper job tensioning the spokes. I have and old set of Ambrosio Montreal tubulars built w/ Wheelsmith 14/15 db spokes that are very durable.

Then again, I do not have knowledge of the Excellence rims. Its possible they are not very good rims, but that is unlikely for the situation you describe.

My advice is to have your wheel guru check the spoke tension on both wheels and adjust them accordingly.

they make rims. My old Montreal tubular rims (probably 25 years old), laced to Campy record hubs with DT spokes, are as strong as a tank! I'm more worried about the cheap new Sun tubular rims on another set than I am about my Ambrosios!

The Excellence is actually a top-end Ambrosio rim and is definitely not at fault. Check your wheelbuild.

I've used wheels built with Ambrosio Balance rims (cheaper and probably heftier than the Excellence) and they have never required truing over two seasons. As far as I know, Ambrosio has a good rep. Perhaps the builder is to blame.

I ride ambrosio excellence rims on two different bikes and they are excellent. I am willing to bet that they are stronger than mavic open pros, which everyone rides and likes. A lot pros ride ambrosio excellence rims on the cobble classics. I am 99% sure that it is the build (or builder) of the wheel, not the rim. The best rim in the world is putty if you don't have a good wheel builder. I think your spokes are not tensioned correctly.

Last year I was tapped by a car at an intersection and my rear Excellence rim was so out of true that I had to get a lift home.

I think that they are fine in normal use but they don't seem very crash resistent. I've had other wheels survive through much worse.
