I have a steel touring frame which will accommodate either 135mm rear hub width or 130mm hubs. I plan on getting some 700c wheels, dyad rims, 2.0mm straight spokes, and 40 spokes per wheel.
Is there any strength advantage in going with a road width hub (130mm) vs a MTB Hub (135mm)? Is there a structural advantage to having that extra width? Also a related question, are MTB hubs generally stronger than road hubs?
I have several choices of Hubs--I can get Velocity hubs (I hear they are actually IRO brand) or spend the extra and get Phil Wood hubs. Also, it I decide to go with just 36 spokes per wheel, I can get either Ultegra or XT hubs.
The use will be loaded touring carrying 300 pounds, rider and load. Any comments on my choices?
