Wheel truing question.(11 posts)

Wheel truing question.amper
Sep 2, 2003 2:47 PM
While trying to true my wheels, I found several seized nipples. The nipple turns but the thread of the spokes do not. I thought I could work with stuck nipple-spoke, but found that it's more than one.

Do I remove the rim tape and ad a drop of liquid wrench or multi purpose oil to the nipples hoping the oil will penetrate the treads and make them easier to work with?
Will this cause the spokes to loosen while riding?

Living in Florida I ride a lot in rainy conditions. Is there some PM I could do to avoid this problem in the future without creating other problems to the wheel?

Thanks for the advice.
You should always use a spoke prep such as..abicirider

wheelsmith spoke prep or one of the other brands on the market, this will solve your problem of spokes sizeing up.

Spoke prep must be applied during the wheel building process. It's intended to keep the spokes from loosening, but will not necessarily keep them from seizing due to exposure to water.

I would apply a drop of liquid wrench or similar lube on each nipple from the spoke side first. Let is set for a while before trying to loosen each nipple. You may also need some pliers with brass or aluminum jaws to grip the spoke and prevent it from turining. Fold a small piece of aluminum shim stock or flashing material (about.010 inch thick) around the spoke and then use regular pliers to grip the spoke.

There is also the possibility that some of the nipples are "bottomed out". If slightly too-long spokes are used, it's possible to bring the wheel into a true condition with no threads left on the spoke for additional trueing. Colorado Cyclist built me a set of wheels with at least half the spokes bottomed out. Couldn't true them up. They rebuilt them for free.

I've dealt with a lot of older wheels where spoke prep made 'em quite a bit harder to true than they would have been otherwise. A good wheelbuilder doesn't need the stuff--just use any old oil. In terms of maintenance you should lube the spokes/nips and nips/eyelets with a light penetrating oil like Triflow from time to time. This is especially true if you ride in the rain a lot. I'd try Triflow for a day before bringing out the nasty stuff like Liquid Wrench or whatever.
Correct, spoke prep isn't necessary.MR_GRUMPY

The only thing that I might add, is when you are building with aero rims without eyelets, I use grease on the head of the nips, to help them rotate. After a short time, the grease washes out.
Do you have alloy nips on these wheels?GregJ

I have never had wheels with alloy nipples but I have seen them hopelessly seize onto the spokes on several wheels belonging to my weight weenie friends. I put a drop of tri-flow on both the spoke and rim around each nipple every few months. If you ever need to have these wheels rebuilt, use brass nipples, lube regularly and you should be fine. The lube whill not cause a well tensioned wheel to loosen.
Yes, alloy nips on the wheelsamper

Colorado Cyclist built the wheels using alloy nipples laced to Mavic CPX30 rims. They are approximately 6 years old and required no truing maintenance until now. Thanks for the advice. I will check the spoke length and try the liquid wrench or similar lube and go from there.
Cut out the spokes, and rebuild with brass nips.MR_GRUMPY

If you haven't built many wheels, and have the time, you can replace the spokes one at a time. That way, you just tighten the new spoke until the wheel is true again.
Colorado Cyclist can tell you what spokes to buy.
Grease the threads during assemblyKerry Irons

For now, you're stuck with dribbling oil or Liquid Wrench in the nipples (spoke end AND rim end), waiting a couple of days, and then doing the vice grips plus twist routine. Hopefully the corrosion bond will break without serious nipple damage. It might be a good time to consider a rebuild, and this time, have the spoke threads greased (brass nipples, of course!). This will not cause things to go loose in the future. It is spoke tension that keeps spokes from coming loose, not Loctite, spoke prep, or dry threads and corrosion. Since your nipples are already corroded, you're on a path for ever increasing deterioration. Get out while the getting is good.
I was taught to use Linseed OilAtombomber

It can be bought for about $5CDN for a litre. During assembly, it aids in lubricating so that even tension can be achieved, and when it dries, it becomes somewhat tacky so it works at securing the thread too, but not so tight that adjustments can't be made in the future.

BOILED linseed oil- the original spoke prep. Add a drop of Triflow between the nipple & eyelet after lacing (before tensioning and truing) and away you go!
