My bike came with Shimano RS10 wheels with an OC rear rim. The OC may or may not help, but the wheel has other issues.
Broke one NDS spoke after about 3,500 miles. Broke another about 250 miles later. I weigh between 205 and 210# and the wheel has just 20 spokes. They are pretty beefy spokes, even the nipples are oversized and need a non-standard spoke wrench. Both spokes broke right where they enter the nipple.
The problem appears to be the rim holds the nipple vertical, so the spoke bends out slightly where it exits the nipple and fatigues there.
Shimano doesn't make these spokes anymore. I've looked at getting other straight pull spokes and rebuilding it, but by the time I'm done it will be $70. Doesn't seem worth it as I will still have a 20 spoke wheel.
