Oh, Surly have got hubs all right. All are forged aluminum with high height flanges, and spin on high load, well sealed, adjustable cartridge bearings over standard sized axles (9x1mm front, 10x1mm rear). This is a common size so it’s easy to find replacements should the need arise or to swap axles if, for instance, you have a QR axle and want to go solid. And did you notice we said the bearings are adjustable? This is so you can adjust play as the bearings wear so you don’t have to replace bearings as often.

Fronts are spaced 100mm to fit most forks.These ones are black. and have 32-holes, You get the idea. They work good, and look good. ‘Nuff said. Here are all the specs:
