Just thought I'd post an update (for what it's worth.)
Ordered the spokes and nipples from rosebikes in Germany, took them to my lbs (Phil Corley cycles) mechanic said that they would be booked in for the next Wednesday. Wednesday comes,phone rings "the spokes are too long"
(thank you,online spoke calculator) collect parts from shop, Saturday comes, phone Germany, they couldn't have been more helpful "don't worry about returning them sir, the spokes should be with you in a few days"
So back to the shop with the correct spokes and other gubbins, again, "be ready Wednesday" Wednesday comes,phone rings "wheels are ready
"back to shop on the Saturday to collect them, I have to say I am VERY impressed with them,infact,I don't want to put on my current bike so am saving them for one of my 'manyframes' (specialized enduro '02-04 linkage anyone)
