Amazingly ENVY will full knowledge they were used on a tandem replaced them under warranty. And their position was improved tech in the interim would make it ok to use the replacement rims.
That said, we decided, with discretion being the better part of valor switch to disc brakes for big mountains.
So, what happened to the rims? Blowout or just warping?
We are having a custom fork built for our Santana so we can have front and rear disc brakes. Part of me wants to keep a rim brake as an emergency brake. One doesn't think of San Diego as particularly hilly, but there are some significant hills; the ride down from Mt. Palomar being one of them.
