Pulled the trigger on some wheels for the build today. I'm going to build up a set with:
Light Bicycle AM733 32H rims (27.5 40mm outer, 36mm inner, ~460g)
Bitex BX211 front and rear hubs (6 bolt brakes, boost spacing, 276g rear, 141g front
Sapim D-light spokes (~310g)
Sapim brass nipples (~61 g)
Should end up somewhere in the ballpark of 1750g, not too bad for USD 705.50 all in. That said, I have to lace them but I'm ok with that.
I just couldn't get over paying 3x for CX-ray spokes. Maybe sometime down the line.
Hubs, spokes, nipples from bikehubstore.com, rims straight from light bicycle.
