|I true my wife's Heliums about once a year. But she weighs only 105# and doesn't put much stress on them. With these extra light weight wheels I think it is important to keep them true. I use a Park TS-2 truing stand. Truing the Heliums is not much different from conventional wheels. But these were built with a lot of tension and the spokes have a tendency to wind up easily. There is very little thread left for increasing tension, I suppose MAVIC wanted them that way. There is an abundance of information available on learning to true wheels. All of the bike maintenance books have instructions, I have the "Bicycling" and Zinn books. There is also information at WWW.sheldonbrown.com and at the Park tool web site.
My advice is to either learn to do it right with a good truing stand or take them to a good wheel mechanic at your favorite LBS. Remember that there is radial truing as well as lateral truing.

|Chen 2 has good input. I have heliums, and have touched up my rearwheel a couple of times. I recommend before you start (any wheel with nibbles) to use penatrating oil or something similar to make sure none of the spokes are frozen in the nipple (which is brass so I've read, hold better then alloy). What I do when truing, is to hold the spoke with pliers to reduce windup. Check for loose spokes first by plucking them. parktool.com has good info.|

|I too hold these spokes with pliers, just didn't know if I wanted to admit that here for fear of being flamed.
|Chen2, It's really sad we have to worry about being flamed nm||Paul|

|Check out The Bicycle Wheel by Jobst Brandt and at $20 it's a real bargain. It's a classic tome on the subject and covers much of the landscape and a quick read. You can pick and choose which sections to read, but it's not quite as much of a "shop manual" for the DIY'er. However, it is very good to have the background in order to true. It would be like trying to land an airplane without knowing aerodynamics or how to fly straight and level. Sure all you want to do is just true, but you're dealing with a rim that is most likely not perfectly true and spoke tensions that will vary. The easiest way to learn truing is to build wheels from NEW components (or at least a new rim). Once you can do it from a good starting point with straight components you'll begin to develop the skills to do with something that's no longer perfect. It is both a skill and an art. Many people can bungle their way through basic truing, but the wheel won't stay true for very long. However, if a wheel is too badly damaged even a master will have a hard time straightening it out. |
All of this is a long way of saying if you just want to get the wheels true so you can ride then take them to a decent LBS and pay them (it really is pretty cheap). If you want to learn how to do it yourself then seriously consider getting some books, buying the tools, talking to skilled builders, and plan on spending time learning to build wheels from scratch (you can re-use hubs, but fresh spokes and rims make life much easier).

It is important to stress you take your wheel to a very reputable shop to have wheels trued. There are many shops around here who have guys who are so respected, that actually true wheels on the side at their home. But there are many shops who simply employ monkeys who will be no better - and most likely worse - than yourself.
I can remember one instance when I was in a rush to get to a shop before it closed. I ran over there without time to take my tire off. I figured it would be okay, I'd just give a tip to the guy. I got my wheel back and they never even touched the tire.
Than again I've had another guy in the very same shop true my wheels while I waited. That guy got a very nice tip.

Thanks for all your help, I am new to wheel truing and I am hoping to give it a try as I ride on the west coast of ireland where the roads are probably not the best :-) and I like to keep my wheels as true as possible . Again I really appreciate all your time and effort.
