To what torque do I tighten the four stem bolts for an EastonEA 70 handlebar stem; is it the same 5nm marked for attaching the stem to the steerer tube? Paddy

Using a torque wrench with an appropriate hex key, tighten the face plate bolts, in one-turn increments and in rotation, to the torque specified on the clamp surface of the stem. For four-bolt clamps, use a cross pattern tightening sequence. For two-bolt clamps, alternately tighten each bolt one turn at a time.

The clamp surface area means the part of the stem, (not the faceplate), on which the handlebar will rest.

What is the torque setting for the handlebar stem

If you have M5 bolts, the max torque is 10NM. For M6 bolts the max torque is 15NM. In case if you have carbon handlebars or even carbon stem, make sure you check out recommended torque for each particular item. Carbon tends to crack if over tightened.

How do I attach the handle bar?

To what - the stem; or is it the stem to the steerer tube?

Did it fall off?

What torsion do i set this stem with EA70 Handlebars

The stem should have the torque settings labeled on it. Ritchey, another reputable stem and bar manufacturer calls for 5nm for the handlebars in their installation guide.

I have the bike together except for the handlebar i cannot figure how the handlebar tightens when you put it in the frame tube

There should be a center bolt that goes through the neck and attaches to a wedge. When you place the stem inside the steerer (frame tube) you simply tighten the bolt with an allen wrench (generally 6mm) or a wrench if it is a bolt type.

If none of this makes sense, send me the brand and model of your bike and/ or a picture and I can help you with more detail.

Headset Torque pressue for a carbon roadbike ...Nothing on the forks or headset ...

The Headset it self does not have a Torque value. The only part of the steering system that has specific Torques are the bolts around the stem, that is why you can't find any values on the headset or fork.

There are either 1 or 2 bolts clamping the stem to the steerer. The Torque of these is usually 5nm - 10nm, depending on stem specs and steerer material.

There are going to be 2-4 bolts in the front of the stem clamping the handlebars in place. These are rarely over 5nm, so 4-5nm is a safe value. But will depend on the stem and bar you are using.

There is one more bolt, the bolt which goes straight down through the center of the steerer. This bolt does not have a specific Torque as it is the compression adjustment for the headset and is done by feel.

With all these bolts you need to use an accurate Torque wrench. If you do not have one, then take the bike into your local shop and they will generally check the tightness of the bolts for free. Accurate torque wrenchs for these applications run from $50 to $250-.

I would like to raise the handlebars. I have loosened the stem wedge nut and the handle bars will not budge. I've tried everything almost to the point of losing the ball bearings in the steering shaft. Are...

Hey joe - Sounds like you have a classic stuck stem. Here are a couple things to try.

1 - Loosen the stem through the top bolt so the wedge is loose, but not removed. The give the top of the stem a good hit or two with a plastic mallet. That should break the bond between the steerer and the stem. If that does not work...

2 - Use liquid Wrench and drip around the stem so it seeps in-between the stem and steerer. Let sit a while then try the plastic mallet again.

sometimes you will need to work the stem back and forth a bit by using the handlebars as leverage and bracing the front wheel between your knees.

If neither of these get your stem loose, then it's time to take into a bike shop.

BTW - stems have a maximum insertion/ extension. There is a line of max extenstion that should be on the shaft when you get it removed. If you discover that the stem will not raise your handlebars enough, then you can get a replacement stem with a higher shaft and greater angle to lift the bars up.

How do i raise the handlebar on a 1999 MGX bicycle?

You can only raise a quill stem os far safely. Loosen the vertical center bolt that's in line with the steerer tube a few turns and then tap down on it with a block of wood or rubber mallet to unseat it. The stem should be loose enough to turn independently of the front wheel. You can also raise it somewhat, but look carefully for the "maximum height" or equivalent markings etched into the stem body. Don't expose any more stem than up to that line. Line up your handlebars with the front wheel and securely tighten that bolt. It should be tight enough to vigorously resist independent rotation when you hold the front wheel bewteen your knees and attempt to turn the handlebars.

If it's a new-style threadless type stem, the maximum height was determined when they assembled the bike because they had to cut the steerer tube to be below the top edge of the stem. Go to a Bike Shop and have them replace the stem with one that has a higher rise or shorter reach.

When the handlebars are turned, the wheel does not turn with them. Kettrike Air Navigator tricycle

  • It sounds like the quill insert is loose. The handle bar connects to the stem, the stem connects to the quill, the quill connects to the steerer tube.
  • while sitting on the bike, tighten the quill adjustment bolt a half turn at a time until the handlebars turn instantly with the front wheel.

I just purchased The Cruiser 24 classis Huffy bike and can not find how to raise the handel bars. Is there a way to raise them up higher?

The center bolt on the stem tightens an expander wedge down inside the steerer tube. Loosen it a few turns, tap down on it to dislodge the wedge and the whole assembly should rotate independently of the wheen and you should be able to move it vertically.

The stem can only be safely raised so far. There will be a 'minimum insertion ' mark etched on it. Don't go any higher than that or you may die when the stem suddenly pops off the bike while you're riding it.

Get it to the height you want, align the handlebars square with the front wheel and tighten the bolt. While holding the front wheel between your knees, try to rotate the handlebars to make sure they're locked to the steerer tube.

If you need more height the stem would have to be replaced with one having a higher rise, shorter reach or some combination. A bike shop will have what you need.

Bicycle handlebars move seperatly from the wheel

My guess is that you are using an older, "quill" stem, which is both the STEM (the extension that the handle bars attach to) and the friction bolt that tightens the stem into the STEERING TUBE

Anyway, what I think has happened is that the quill is either not tightened or (because you said you tightened everything) the angled nut at the end of the quill isn't aligned properly and is tightening.

HERE is a great diagram of the quill stem. What I think you'll need to do is:

1 ) IF you have already tightened the bolt at the top of the stem (usually under a little plastic cap, like the one at the top left of the stem in the diagram). Then Untighten it and if you can pull it out make sure that the angled nut (shown at the bottom) is resting properly against the angled shaft of the quill (the vertical part of the stem). As you can see these will spread apart as you tighten the bolt, making them wider and holding them in the steering tube. The idea is to realign the angled nut so it can properly contact the shaft and spread.

2) if you haven't tightened this bolt (maybe because it's hidden), try tightening it a small amount and see if that changes anything.


This was all written assuming your bike is not using the newer "threadless" setup, which would probably have been fixed if you tightened down the stem (PICTURE OF THREADLESS STEM)
