I have a pair of Kinetix Pro wheels on my Dahon folder. The front wheel has developed a wobble, so I got out my spoke key to fix it and.... there are no spoke nipples next to the rim. (The slight bulge you can see in the picture is due to the butting of the spoke, it's not a spoke nipple).
Presumably it's possible to true them from the inside of the rim, but if possible I'd rather not rip off the rim tape only to find out that I don't have the right tool - so if anyone knows what I need, I would be very grateful.
