A few days ago there was a question about a source for cheap CX-Ray spokes($1.75 each with brass nipples), but it was unclear whether they stocked longer lengths needed for 700c hoops. Now we have the answer.

Dan's Comp does have road lengths such as 250-300 mm, but does not maintain as large a stock as for BMX. When you call to order, there may be an outage. They will custom cut to fill in sizes, but the bladed spokes have such short end sections, the amount that can be done is limited.
