I just had another set of wheels built up with some rims from Peter at XMCarbonSpeed. It's a good as time as ever to start a wheel thread. Feel free to add to the list so people can see what some options are.
This set consists of:
AS738C rims from XMCarbonSpeed.com, 38mm outer, 32mm inner, 28h, 820 grams for the pair, measured ERD 552mm to top of nipple head
DT Swiss 350 Centerlock Boost hubs, 28h, rear is running the 54t ratchet
Sapim CX-Ray spokes also from XMCarbonSpeed
Sapim double hex self locking alloy nipples
Decals from Slik Graphics (I live in a color matched world, I blame it on my 2 daughters, don't judge me
)
Total cost with labor was $950, that's using full retail on the hubs and $100 in labor.
