mavic stops cracking?

Mavic always denies their rims are prone to cracking and
refuse any guaranty claim. But now they make a rim (xc
717) that is reinforced to stop micro fractures (they
call it H2).

Seems to me they started to fix the cracking problem without
admitting their rims suck.

Is H2, Hammer Hardening, really making the aluminum "locally stronger" or does Mavic need another marketing tool?
Where does H2 start and stop? What about that boundary?
I will need a better explanation before I am convinced.
I have used most all Mavic previous generation rims without any cracking. However, I certainly have talked with and read about many cracking problems.

My CrossRides have an unconditional guarantee. If they break
FOR ANY REASON (so tells me my LBS) they will replace them.
Grated, I had to pay an additional fee, but a replacement
for 8% of the original cost isn't bad.

They did the same thing when they re-did the Reflex clincher
into the Open Pro, when so many had failures...

If the problems are being caused by the presence of a lot of
unrelieved stress risers in the extrusion, and they're
actually stress-relieving the rims in the manufacturing
process, then I'd say it *may* have a chance of making a
difference. Based solely on what little information they
seem to be making available, though, it looks like buzzword
marketing instead of a real change.

Time will tell the real story. Either the rims will fail, or
they won't. Those who have moved away from using Mavics in
general will most likely stay away from them until
experience proves that it's either safe to go back to them,
or that the readily available competing products are not
significantly better.
