I have a set of Shimano R560's that have flat, bladed spokes (16 front & 20 rear, from memory). They are a little worse for wear after a couple of years and at least 10,000 kms. My usual LBS has had a go at truing them but they continually go out of true just with everyday riding.
Does anyone know of any special techniques required for these types of wheels?
I also ask since I have another set of Ksyrium wheels, and while they have been fantastic over the past 5 years, I want to be prepared should they ever get out of true.
