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!
