How long should my steerer tube be?
The steerer tube must not be so long as to protrude from the top of the stem, preventing the headset from being tightened, but also must be long enough to allow for enough clamping contact with the stem.
Can you extend the steerer tube on a fork?
Yes it can work – but theres a couple of points to note. However, a threaded steerer would be locked into the headset so the strain of keeping the fork attached would not be taken by the quill.
How do you measure a steerer tube?
Measure your fork steerer tube You need to measure it in two places. The outside diameter (OD) of the top section (where the stem clamps around, as in the above pic) and the outside diameter of the very bottom bit where the steerer goes into the fork crown (where the headset crown race sits, as in the pic below).
Are all steerer tubes the same size?
Most steerer tubes will be 1 and 1/8th of an inch or 28.6mm some are 1 and 1/4 of an inch or 31.75mm but much rarer. Just measure the inside diameter of your existing stem by taking off the top cap.
Should you cut steerer tube?
Before cutting anything, unless you have a special stem that says not to put spacers above it (these are few and far between, the “exceptions to the rule”) you should lower your stem and ride like that for a week or two. See how it feels and only after that should you make a decision about cutting your steer tube.
Are steerer tube extenders safe?
Steerer extenders should never go on carbon steerers because the stakes of the steerer failing without warning are too great; even in the case of a carbon steerer that was cut too short, they should be avoided because of the extra stress their pinch bolts put on the steerer.
What is steerer tube diameter?
FORK STEERER TUBE DIMENSIONS – Almost every single modern bicycle fork has an upper steerer tube outer diameter of 28.6mm, or also referred to by 1 ⅛ in.
What is a steerer diameter?
How high should my stem be?
It is best to set the height first, then adjust the stem for length. 1. Place the 4 foot spirit level on the middle of the saddle and extend it outwards over the top of the handlebar. For a performance road position, the top of the handlebar should be about 5-6 cm below the mid-point of the saddle.
What do you need to know about steerer tubes?
Your fork’s steerer tube length depends on a number of different factors, including the bike’s head tube length, headset stack height ( including the cups, bearings, crown race and any associated parts) required headset spacers, and the stem’s stack height.
How do you install a steerer tube on a bike?
Step 1 – Install the headset into your bike’s head tube ( refer to the headset manufacturers instructions) and slide the fork up and into place. Take a moment to be 100% sure that the fork is fully seated into the head tube and that the upper and lower headset assemblies are seated correctly.
Which is the best way to tighten a steerer tube?
In the photo for step 2 you could add a spacer on top of the stem and then tighten it as normal. This would mean that all of the stem grips steerer tube, making for the most secure fit. In step 3 the top ~3mm of step isn’t gripping anything and the top cap will press directly on the stem.
Where does the steerer tube go on a Magura Thor?
The steerer tube, in this case a tapered version on a Magura Thor fork, is highlighted above in red. This passes through your bike’s head tube, along with all of the headset parts, and the stem is clamped in place at the top end.
