• I haven't done it personally, but I am in the same boat as you and wanted to extend my short threaded steerer into a ahead one.

    Theoretically this product exists:
    http://bbbcycling.com/bike-parts/headset-parts/BHP-21 which can be had on wiggle for around $20.

    Which gives you something like this:

    The good thing about this is that internal bolt you see is threaded, so you can preload the stem with a top cap. If it was me, I would make sure the lower stem bolt is clamping onto the original steerer at least.

  • I've been using an adapter like this for years and still have all my teeth. Really good and easy solution in my opinion.
