It all comes down to the type of riding you’ll be doing on them.
In my experience, they weren’t up to the abuse I wanted to subject them to. I dinged the rear and put it right out alignment. Took it to the old LBS, they spoke to Mavic, and to fix would require sending it back to Mavic, where they would rebuild the wheel with a new rim and new spokes. Cost? £220. I bought a Hope/FlowEX instead.
In fairness, I was probably asking a lot of them.
I only found out about their MP3 cover afterwards. If you get them, get this, as the rebuild I required would have been covered.
As has been mentioned, the rim is very narrow, but that might be fine for you. For me, the tyre profile you get from a FlowEX is much nicer, even on narrow mud tyres.
