forks. how i figure out the size?

Question

how do i measure my steering tube length? what does 11/8" or 11/14" mean? please help. im trying to find another fork for my hardrock.

Answer 1

Steering tube length is measured from the base of the tube (where it intersects the fork) to the top. Generally, this will be specific to the headset it was last inserted into, so if buy another used fork, make sure it's at least that length (or longer). 1 1/8" & 1 1/4" are the diameter measurements. If you've got a hardrock, my bet is it's 1 1/8", but grab a ruler and verify.

Answer 2

You have two questions there. The steering tube length is the length of the steel "shaft" of the fork from the crown to the top. This section is hidden by the head tube of your frame and the stem of your handlebar. The only way to measure this is to take the fork off. If you are buying a new fork, it shouldn't matter because they generally come longer than needed and you would cut it down to size. If you are buying a used fork, you will need to know the length so the used fork will have a long enough steering tube. The other measurement is the diameter of the steering tube. Depending on your fork and your frame, the diameter may vary. If your hardrock isn't very old (pre 2000) it is likely 1 1/8, but I would check to make sure before you buy something.

Answer 3

1 1/8" is the diameter of the steerer tube. A HardRock (2000 or later) is usually 1 1/8 size. Measure the length from the very top to where it meets the fork. Hope this helps.

Answer 4

if you are reffering to a Specialized Hardrock, then you have a 1 1/8 inch steerer tube. that refers to the tickness of the steerer tube. 1 1/8 is the standard these days, but some proprietary companys will use other sizes. some brands are moving into OnePointFive (1 1/2 inch) for more stiffness, but those are only for the heavy duty bikes. as for the length, when you buy a new fork, always go for a long length. you can always cut it down to the rite size you need, its quite easy. its measured in millimeters. it represents the length of the steerer tube from top to were in connects to the crown.

Answer 5

Besides what the other guys said, when choosing a fork, make sure the travel is similar to what you have now. I would suggest going to at most a 100mm fork up front, or maybe 80mm. If you get a fork with too much travel, you might be putting too much pressure on your headtube over time, and also, you're modifying the geometry on the bike. So try to keep a fork with similar travel.
