FAQ: How To True A Mountain Bike Wheel?

How true do MTB wheels need to be?

“An out-of- true wheel will be wobbling laterally, from non-drive side to drive side,” says McCloud. Lift up your bike, spin a wheel, and take a look at it from the front or rear. If you can see it wobbling more than five millimeters left to right, it’s time for a wheel true.

How much does it cost to true a mountain bike wheel?

If the wheel is fixable–it generally looks good but has a wobble–you can expect your local bike shop to charge $20 – $30 to true it using professional equipment like a truing stand for the perfect line and roundness.

How tight should MTB Spokes be?

Once the rim is free from blips and serious flat spots, check the tension of the spokes. Put your thumb around one spoke and your fingers around the spoke next to it and squeeze. The spokes should feel tight and firm. They should have just a little give when you squeeze them fairly hard.

When should I true my wheel?

If your spokes are so loose they rattle, they’re providing virtually no strength to the wheel structure. It’s no better than if that spoke were missing or broken. It’s a big indicator that your bike wheels need truing.

What does truing a wheel mean?

Wheel truing is the process of using a spoke wrench to change the tension of spokes to improve the straightness and roundness, or trueness, of the wheel.

Is it safe to ride a bike with a wobbly wheel?

An unbalanced mass rotating at high speed can cause a significant amount of wobble. And either will make the bike harder to handle at high speeds (especially those 50mph downhills). In theory, an out-of-true wheel probably affects spoke life, and a wheel, once out-of-true, will tend to get worse over time.

Why do bike wheels go out of true?

One of the most common reasons wheels go out of true: loose spokes. Check tension by squeezing two spokes at a time between your thumb and fingers, says LaPorta. A really loose spoke will be obvious (as you do this more often, you’ll be able to feel subtle differences). If the wheel’s still wobbly, it’s out of true.

Do you really need a truing stand?

All you really need to true a built wheel is a spoke key. A tension meter is nice, not for getting tensions even, but for getting them to spec for the rim. A wheel stand is the last thing you need, you can use the frame and a piece of plastic and some tape to make feelers.

Can you true a wheel with the tire on?

If it’s just a minor truing, it’s fine to keep the tires on. If you have single wall rims, deflate the tires first. For a more major truing, I’ll remove the tire so I can watch the radial true, install, inflate, deflate, and touch up the wheel, then reinstall the wheel on the bike.

Which way do you turn spokes to tighten them?

Note that the spokes have nut-like devices at the rim called nipples. When viewed from above, nipples are turned clockwise with the spoke wrench to tighten spoke tension and counterclockwise to loosen it. To ensure that you turn the nipple the correct way, always rotate the wheel to bring the nipple to the top first.

How long does it take to true a bike wheel?

Except when you complain. Then it takes 1-2 weeks. During the busy season, which is now, a bike mechanic can do 5-7 tune-ups a day, less if he has to deal with customers. BTW, if he trues your wheel, and your derailleur shifts into the spokes, you are ok with that, right?
