How Long Is Steerer Tube On New Forks?
Greetings. I bought a used Rockhopper frame I want to build up. The first order of business is some suspension forks. I'm wondering about the length of the steerer tube. I'm looking at a set of forks on Ebay that has a 9" long steerer tube. I'm wondering if that's enough. The length of the head tube on my frame is about 6 3/4" With the headset and the stem, I'm wondering how long of a steerer I need.
I'm also wondering if there's a standard length steerer length when you buy a new fork. I'd like it as long as possible so I'd have options for how high I could mount my bars. I'm 6'4". One of the criticisms I have of my old Stumpjumper from the 80's is how much lower my bars are than my saddle. I think the salesman sold me a frame that wasn't quite big enough for me. I want to make sure my "new" bike fits better.
Thanks!

Wow. That's a LONG head tube! Do I see that this is a 23" frame?

I've got 2 1/4" of steerer and three 5mm spacers, so you ought to be ok unless you have to jack up the stem..
Even then, you can sort out bar height with risers and stem length/angle. But you probably knew that already.

Standard uncut length on a threadless steerer tube is 265mm.
Your 170mm head tube length + the stack height of the headset (roughly 28-30mm) and the clamping area of the stem (maybe 40mm) means you'd need at least a 240mm (9.4") long steerer tube.
Looks like you can add in a few spacers and forgo cutting the steerer at all.

So, SVR, just to confirm here for those of us like myself just picking up this info for the first time- 265mm is THE INDUSTRY STANDARD supplied uncut length for threadless steer tubes, all rigid and suspension forks. Thanks, I'm here to learn.
