Schmidt SON Deluxe Dynamo Hub: Wide
The Schmidt SON Deluxe wide body has the same great internals as the regular SON Deluxe, but with wider spaced flanges. The standard Deluxe hub flanges are spaced 50mm apart. The Deluxe Wide body has flanges spaced 68mm apart. I have put thousands of on and off road miles on my standard Deluxe hub without any issues. When I built up a new wheel for my touring bike, I went with the Wide Body hub for better bracing, especially important when carrying camping loads on the front of the bike on rough roads and tracks.
Still the lowest resistance generator hub out there. 412 grams. 32 or 36 hole only.
