Uncut steerer tubes too short for 21" Frames I am restoring two old bikes a 1996 Trek 8000 and 2000 Fuji Aloha. Both are 21" frames. The problem I am having is getting forks that do not cost $1000 and have steerer tubes with sufficient lengths. I am finding forks with uncut tube lengths of 250mm etc... The longest I have seen is 300mm. I think for the Trek MTB i would need around a suspension fork with around 320mm and for the racing Fuji, I would need a road fork with an even longer tube than that ( maybe 350mm). Do they make forks intended for a certain size bike or one size fits all?

Thanks in advance.
When I have had this problem I have paid to have extensions welded on to the tube. The welding must be done in a lathe, or a proper rotating pipe welding jig, so it's not a DIY project. Or look for a fork with a removable steerer tube and fit a longer one.

One advantage you have here is that many (most?) steerer tubes are still steel, so it's usually possible to weld them without destroying them. In my case I've used fairly cheap forks, so even if one gets trashed during the process I'm only out $100 or so. Also, with a little work you end up with a tube stronger than the original because you can sleeve a second tube inside the original and weld that at the fork crown too. Or if it's a tight fit, just leave it there.

For my bikes there steerer lengths required have been unreasonable (in the worse case, about two metres for a tall bike), so there was never a question of being able to find one pre-made.
