I have a slight buckle in the front wheel of my 1989 R80GS. A quick search of this forum and I can see that Devon Rim Company are recommended. But that was back in 2005. It is mentioned that this is the only place to get them done. 
Can anyone recommend anyone who is straightening these wheels, I understand it is a specialist job? Any recommendations a bit closer to East Midlands would be much appreciated.
