I've a Dean Ti frame but the head tube is too short, anyone had any experience with head tube extensions? There is a Canadian company that sells them, I'm just concerned about the feasability of whether an extension will work.

There are two types up of head tube extenders that I am aware of. Serotta sells a 2 cm titanium extender that fits between the head tube and the upper part of the headset for $60. This won't work, however, unless you have an uncut fork, a longer than usual steerer tube (eg, with lots of spacers already) or you're buying another fork anyway.

Your other option is steerer tube extender made by Zoom and some other parts companies for about $25. This will work even if you have cut the steerer tube and can raise the stem/handlebar quite a bit. It actually bolts to the existing the steerer tube. Until recently, these were only available for 1-1/8" steerer tubes, but I have recently seen them available for 1" steerers. I think you can find a decent selection of these extenders at some of the internet shops, such as www.bikeusa.com. I am not sure how they work, but it seems like a worthwhile option if you need to raise your handlebar and don't want to shell out the bucks for a new fork with an uncut steerer.

Bikeusa has a bunch of different sizes and models of steerer tube extenders listed for $18 each. Here's a link to the page. If the link doesn't work, go to www.bikeusa.com, then components, then stems and scroll down to find the section.

If you give them a call, they might have firsthand experience about how well they work. I had the same problem with a frame a couple years ago and my bikeshop claimed that 1" steerer extenders were not available, although they stocked them in 1-1/8". Maybe they were just trying to sell me a new fork. I ended up buying a new, better fitting frame instead.

I have one on my tandem and it seems to work fine. Seems pretty solid and I don't really even notice it when I'm riding.

Of course tandem riding is different than solo.
