I just looked up the Rolf wheels and don't think they'll be strong enough for heavier riders. Then again, I haven't compared specs between the two sets Rolf sells for 230lb rider Vigor RS and Echelon to my Aero X stock wheels on my 07 Giant OCR C3. Between my Aero X and Rolf's wheels, they have a similar style and spoke layout.
My AeroX are creaking everytime I stand up and ride for start ups, climbs, and sprints. I've added a little oil in between where the spokes cross per my LBS. That hasn't cured the problem. I've had two different bike shops true them and still have the same results. I'm now looking for stronger wheels. Looks like I'm going with 32 spoke something.
I'm sharing this with the OP so he can get an idea that maybe these might not be the best choice for heavier riders.
