for reference, I'm 165, and I can make factory Easton EA90 SL's (24F-28R) rub the brakes when I'm out of the saddle. Add 75 pounds of muscle, and I have no doubt you could get them to rub from the saddle.
The wheel does not rub when I am on the saddle, only when I get up and really get on it like on a steep climb. If I don't tilt the bike, it does not rub. Neither the Ksyrium nor the Enve rub no matter how much I tilt the bike.
that build, on those hubs, should be ok the only thing I would recommend different besides a rebuild is maby adding on some tougher spokes on the drive side rear wheel for stiffness:http://www.sapim.be/spokes/butted/strong
thats what ergott is going to do for me on my build here in the next few months...
It's the front wheel that occasionally rubs when laterally challenged, not the rear.
I have heard of Eric's work and have read a lot of his posts. He seems to know his stuff. If I understand correctly from his past posts, he recommends going to heavier spokes like the Race or wheelsmith 14/15 on the DS when he is using aero spokes like the cx-rays on the other 3 sides and the rider weight, style and roads need it.
The Force spokes used on my set are a step above the Strong, very stout, very robust spokes. Called Sapim and asked them the very same question, their answer was Force are more than enough for the application. Before I decided to go with the C2s, I called HED about their clyde Ardennes build as well, they use 24/28 and comps. Although they said the Ardennes would be fine for my weight and style I opted for the sturdier built with the C2.
At the end I decided to go with a local shop to avoid the hassle of sending wheels back and forth over the mail in case anything happened...........well, you know the rest.
