Thanks. The spokes are these:
Universal Cycles -- DT Revolution Spokes - Silver
DT Revolution Spokes - Silver
2.0-1.5-2.0 stainless steel butted spokes
How can I tell what nipples I need, both brass and alloy?
In the past, Ive simply gone to the bike shop (Universal has a retail store near me), specified my desired spoke, and asked for nipples as well. They choose the nipples and it has always simply worked. That is what happened this time, but the nipples don't work . . .
