Stiffness advantages of large flanges.
https://share.ovi.com/media/currentre...resident.10392 I built a new wheel using the spokes from the old one DT alpine. The old wheel used a low flange Shimano deore hub and the new one uses a Shimano large flange hub. The spoke count went from 36 to 32 I expected it to be more flexible but I couldn't tell the difference. After doing some measurements and some math the large flange does increase the bracing angle of the spokes. Of course the large flange is much better in transmitting torque. After testing this wheel to destruction I will build a new wheel with 36 spokes and an XT hub. By the way the Shimano FH756 hub does not have the steel insert for the freewheel like the FH750. Still the large flanges move the bearing out 10mm reducing bent axles they are a good choice for Clydesdales on a budget.

Tyeing, and soldering, the last cross of the spokes will further stiffen the wheel, laterally..

Larger flange means shorter spoke which will yield a stiffer built wheel.. Not many companies make large flange hubs anymore.. I think American Classic is one of the few rear hubs in large flange. They only come in 32 hole max, I have a built wheel on an older AC 36 hole and it is very stiff..
