Very interesting article. I have been annoyed by brake rub when sprinting on my 50mm carbon tubular race wheels. The front wheel only. I noticed that it has radial spoking elbows out, which means that the spokes go from the hub to the rim on the inside of the hub flange. I have considered rebuilding them with the elbows in, thereby widening the brace angle slightly. It may be enough to eliminate the brake rub. Or it may be a huge hassle for nothing....
