Rear droputs are spaced at 135 mm.
Road rear hubs have 130 mm spacing, while MTB ones have 135 mm spacing.
Most road bikes have rear dropouts spaced at 130 mm, though many new frames come with "universal" 132.5 mm width - which means they can accommodate both 130 and 135 mm spaced hubs. 135 gives a wheel more lateral strength and if the frame can accept 135 mm, I'd go with it for commuting.
Also, 36 spokes and 28 mm tyres - if there's room for them - great choice for durability.
