    Your giant comes with the overdrive steerer tube so my guess would be that it doesn't fit but I am sure giant will have some overpriced variants that you will be able to buy

    The Aluxx Defy bikes use the standard Overdrive 1 1/8" aluminium steerer, you are referring to the Overdrive 2, 1 1/4" steerer fitted to the Defy Advance Pro and Advance SL models.

    OverDrive

    FEATURES: Giant’s original oversized fork steerer-tube technology. Designed to provide solid front-end steering performance, the system’s oversized headset bearings and tapered steerer tube provide optimal steering stiffness. Road models feature 1 1/8-inch top and 1 1/4-inch bottom bearings, while the mountain version features 1 1/8-inch top and 1 1/2-inch bottom bearings.

    OverDrive 2

    FEATURES: Giant’s most advanced fork steerer-tube technology. Oversized headset bearings (1 1/4-inch top and 1 1/2-inch bottom bearings) and a tapered steerer tube combine for unprecedented steering performance with no additional weight.

    Now this may seem like a dumb question but I've never seen one of them before.

    Does this mean that if you have been given a set of forks that have been cut too short for your frame you have been given that you can bolt one of these on extend your steerer?

    Or am I being a schmuk?

    Not sure whether the OP has a cut down O.E. steerer tube, I had in mind that he may be wanted to do a Jeremy Corbyn job to get his bars higher than he could by flipping the stem.

    I suppose you could use one on a cut down aluminium steerer tube, if there is sufficient length left for the extender to clamp onto.

    Ah got you DJ58, I knew a mate had issues fitting this and a longer stem on his defy but his was indeed the advanced pro model. Good news for the OP

    I'm assuming from your query that you have acquired a bike where the previous owner has trimmed the steerer to a point where you can't get the correct height for your bars using a normal stem.

    Other options are available rather than the steerer extending device you linked to. Depending on how much extra height you need you could

    1. Buy a stem with the capacity to vary the height of the bars by using dedicated shims eg The Specialized Comp Multi Stem which comes in 12 and 24 degree variants with shims that can add (or subtract) height as necessary

    http://www.sigmasport.co.uk/item/Specialized/Comp-Multi-Stem-12-degree-2014/121V?gclid=Cj0KEQiAqqO0BRDyo8mkv9y259EBEiQApVQD_QIzwVtLyVhNcvKk4DcTqOe8vQB0HZfltIJ8qUcHiF4aArjs8P8HAQ&gclsrc=aw.ds

    2. You could buy one of the speciality stems that have a fixed angle of pitch to suit your needs
    eg

    http://www.wiggle.co.uk/bbb-bhs-25-highrise-oversize-stem/

    3 You could buy an adjustable stem to give you an infinite variety of angles (within limits)

    http://www.wiggle.co.uk/bbb-bhs-29-highsix-oversize-adjustable-stem/

    None of these options is ideal and will have penalties in terms of weight and cosmetic impact.

    Maybe a new fork/steerer might be a better solution.
  • Thanks for all your help

    I've already fitted this stem:

    http://www.wiggle.co.uk/bbb-bhs-25-highrise-oversize-stem/

    I'm fitting the above stem and the extended steerer as I have ankolosing spondylitis which makes it difficult to comfortably look up with a normal stem/steerer set up, apart from a custom frame it seemed the best solution, it won't look as "cool" as a slammed set up but it gets me out riding.

    Any advice on other solutions would be most welcome.

    Cheers

  • Out of interest, how does one set the preload? Is there a massively long bolt that goes through the topcap, stem and the extender down to the star insert in the fork?

    Thanks.

    That looks like the same angle stem i have fitted to my mtb.
    On the road bike, i just spin the handlebars up until it gets to the right height.
    Works better than the extreme stem, just got a tcr and did the same thing.
    Leaves it with bar ends like a mtb and works for me.
    As you say, it gets you out riding.
