Reading the last copy of the CTC mag Chris Juden has an article on how to replace your rims. It seems very simple to me and also very timely in that my open pro rim exploded the week before the mag dropped.
Anyway the hubs are still good and decent rims are relatively cheap so I'm thinking of giving it a go. I have a truing stand and from the article this seems to be enough. So why don't I just do it? Well its a rear wheel and I'm sure there's some reason why the tensions should be different on the drive side. It's only for my winter bike and at the very worst it can serve as my turbo wheel.
Maybe this just isnt that important as Chris didn't mention it - I also have a feeling that wheelbuilders like to keep a certain mistique around the 'art'. Be interested in hearing experiences.
