Increase steerer tube length?

[myersv]

I bought a tora fork with a 7.25" steerer and today they tell me that it's too short. THey say I need 8.25-8.5".

Is there any way I can use that fork or do I have to buy a new one? I have a rocky mountain 70rsl frame.

Thanks.

Double check their measurements.
How tall is your headtube without the headset?
How tall is your headtube+ headset in combination?
What is the stack height of your stem?

If your headtube + current headset + stem + thin spacer are in the vicinity of 7.25" you may be okay.
If not, you may be able to swap to a lower stack headset and lower stack stem.

I went through this once, here are some links i had saved for short stack height stems, sorry some are showing discontinued but I'm on my phone so i can't go find recent links. you might be able to find them on ebay or the manufacturer might make a newer model now:

You might be able to replace the steer tube.

Check out this thread : Replacing Steerer tube possible?

If you want a longer steer tube you will need to replace the entire CSU (crown steer unit) Most find this cost prohibitive. There are a few posts to be found where parts are machined to extend and what not - they must have good dental insurance.

This is probably one to chalk up to experience. 7.25" is not really long enough for any adult-sized bike; the person you bought it from must have been extremely short. If you were close, then yeah a shorter stack stem or headset would help, but you aren't going to get an inch or more that way. The difference between the shortest headset I've ever seen and a common size is maybe 8-9mm (and that's a crank bros headset, which I wouldn't run for any reason ever), and you might get another 5mm with the stem - less than half what you need.

There have been a few posts on welding an extension on or something, none to my knowledge have worked out well. You might be able to come up with something that would work, but not that would be cheaper than replacing the CSU, with will probably cost more than you paid for the fork. And of course anything you came up with, I think you'd be constantly questioning.

Just get a different fork....that's a big difference. At least you now know what you need.

Thats why you see a lot of forks with short steerers going for peanuts - they don't fit 90% of bikes. On a Tora I don't think there is anything worthwhile you can do other than try to sell it
