Looks like 308mm front spokes, with a 64mm hub hole diameter. Spokes look to be double butted 0.065/0.080 inches (1.65 and 2mm, or 16 and 14 gauge, unless I'm mistaken). So DT Swiss has DT Competion spokes, which are available in 2x1.8mm, and DT Revolution, at 2x1.5mm. Sapim has a 2x1.65mm, the D-Light, which matches exactly. They're all a bit above a buck a spoke, with a nipple (!).
