commuting rim suggestions?

I'm looking for suggestions for a rim for a commuting wheel. DH's current wheels are 32-hole Ultegra hubs on Open Pro rims, but he's had some trouble lately with the rim itself deforming in isolated spots, and no amount of truing will fix it. I'm careful to check trueness, roundness, dish, and tension every time, so that's not it.

At this point, I'm thinking that he just needs a stronger rim for his rear wheel. I'd prefer to stay with a 32-hole rim, just because he already has the hubs. He commutes over very crappy roads, and he's a Clyde.

I'm thinking something like a Salsa Delgado Cross or a Velocity Dyad. Any other ideas or first-hand experiences?

TIA!

Two words: tandem wheels :)

Maybe for hubby.... but I think she's looking to use his old hubs.

I've had bad experiences with Velocity rims - I had them on my commuter, and mind you I live in Seattle so they get a great deal of abuse from wet gritty roads in the winter...., but I found them to be very soft and to wear *very* quickly. I didn't have dyads - I had deep V's, but I'm thinking the quality of the metal is probably not much different. I've had pretty good luck with Mavics - not Open Pro's which are lighter racier wheels, but with CXP22's which are a bit more heavy duty.

I've had great luck with Dyad's. They are frequently used as touring wheels, and I have one on my tandem. I don't ride much in the rain, so I can't speak as to the grit durability.

I use Mavic A319s ims for commuting/light offroad. Not light but they are inexpensive and fairly tough. I have re-used the same spokes when replacing an Open Pro rim with an A319 - they were DT Champion stainless double-butted, no probs so far.

If the rim is deforming like that, it may be that so much metal has been worn away that air pressure from the inner tube is pushing the rim out. Watch it!

This is all good information- thanks, everyone!

Christopher, thanks for the thought about the air pressure pushing the rim. I hadn't considered that, but it could definitely be a dangerous situation!
