How do you tension a spoke on a mountain bike?

How tight should MTB Spokes be?

They should be nice and tight and even all round. Any spoke that is tighter than the rest may cause ones next to it to loosen, and is more likely to snap as it’s taking more strain than it should do. Loose spokes arent pulling their weight and will cause the wheel to buckle quickly.

How do you calculate spoke tension?

If the tension of two laced spokes is very different, you will hear a dull thud. Pull the spokes across each other with your fingers to see which is looser. Lift the looser spoke away to pluck the tighter one alone and check its pitch. Check for rim damage or a crooked rim joint near the unequally-tensioned spokes.

How do you adjust spoke tension?

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.

Which way do you tighten bike spokes?

The spokes on a bicycle wheel run from the rim to alternate sides of the hub. In order to pull the rim back into true, you have to tighten the spokes that lead to the side of the rim opposite the bump. To tighten spokes, you don’t actually turn the spoke. Instead, you turn the nipple that holds the spoke into the rim.

How do I know if my spokes need tightening?

Take 2 on the same side that are close to each other and squeeze them. If they move easily you need to tighten them. All spokes should move a little and make a rubbing sound that is close to proper tight. If they move more than that they are loose.

How do I know if my spokes are tight enough?

Get things pretty darn tight

Looking down, you’ll be turning the wrench counterclockwise. Hard to describe the tension precisely without a tensiometer, but it should be very tight on the tighter side. I shoot for 120-150 kilograms of force per spoke on the short side.

Should all spokes be same tension?

Spoke tension is important to ensure your wheels are strong, reliable and long lasting. … Spokes that are too tight will cause damage to the rim, spoke nipples and hub flanges. All of the spokes in the wheel should have approximately the same average tension.

How important is even spoke tension?

And if you have proper spoke tension, your wheel will stay true longer and your spokes and rim will last longer. When your spoke tension is too low, your spokes tend to loosen even more each time you ride. … On the other hand, too much spoke tension can lead to premature failure of rim, hubs, and, of course, spokes.

What happens if you over tighten spokes?

It is rare for spokes to be too tight, but it is very common for them to be too loose. … In this situation, tightening just the loose spokes will cause the wheel to bend even more, in the same direction. Instead, the rim should be bent back into shape first.

Are loose spokes dangerous?

Never ride with a loose spoke. The friction created will cause the rider to burst into flames and may even cause the Earth to slip off it’s axis. A wheel with so few spokes, and has a loose spoke, AND is still true, has major problems.

Why do my spokes keep coming loose?

Spokes twist when the nipple is tightened, which may result in a spoke that looses tension very quickly while riding, putting the wheel back out of true. Spoke prep helps get the nipple up to tension with reduced twisting of the spoke.

Are bike spokes reverse thread?

Spoke nipples aren’t reverse threaded, but when you’re turning them, it seems that way because you’re turning them from the bottom, not the top like you would a regular nut or bolt. … To avoid this, always loosen every other spoke the same amount you tighten the others.

Can you tighten spokes with pliers?

I know a lot of people are telling you to take it to the bike shop, but if you have just one or two loose spokes it’s fine to tighten them with pliers or an adjustable spanner. … An adjustable spanner (wrench) may work if you are very careful, but a spoke wrench is a much better way to go.

How true should a bike wheel be?

The wheel does not have to be perfectly round or true; slight runouts are acceptable (a few millimeters). As long as there are no loose spokes and the wheel is reasonably straight (the rim and tire mustn’t rub on the brake pads), it will ride nicely and hold up fine.
