@Skyliner : Thank you, that is a lot of useful info. If it only had been a matter of making a spacer or two it would have been easier and cheaper with an xrl rim. And perhaps lighter. Ideally i would like a crf rear wheel but i realize that hub is so much narrower that it's not doable. But you are right, it's easier to have the original hub to work with. I have done a couple of downhill mtb wheels and it's basically the same but on a larger scale. But how do i "watch for the angle of the spoke holes"? They are what they are right? There is no specified angle on a new rim and i don't have any value to start with anyway right? How do you solve it? Drilling the holes? @plumer1kt : Thank's for the tip, that seems like a nice affordable rim! @TransAfrika : Thank you. Yes africanqueens have some really nice builds and parts! I remember like 20 years ago they had AT and Varadero builds that were on a level with the new crf 1000 AT. But i have a feeling that it would be quite expensive to first buy a decent wheel and then send it to the pro's. I definitely want 2 sets, one 17" for the tarmac and one 18" for the dirt. And perhaps even a 19" front to go with the 17". But there is alot of work before that!
