As Hillrider correctly clarified, all MTB hubs are going to be 135mm, assuming a quick release hub.

If you want easy service, 36H, and Shimano, you likely won't find anything better suited than these Ultegra hubs: Shimano Pair Road Hubs Ultegra 6800 11Spd - Hubs & Skewers - Ribble Cycles

The price should make you happy, too.
