I have a fox triad shock i2i 184mm stroke length 44mm =120mm of rear travel on my Spesh Stumpjumper fsr.

Would a shock with a 190mm i2i and stroke length of 50mm steepen the headtube angle too much and higher the BB too much, or would it not be noticeable?

    Why do you need a different size shock for it?

    It might not even fit and you are most likely to lose quite a lot of travel.

    The stumpjumper has a proprietary connector where the eyelet would normally be anyway so unless the shock is identical it will not fit.

    What model year? On an 08/09 it's a good set up. It yields about 134 mm travel, and you can run extra sag to compensate for the head angle change, or leave as is. The change in angle is barely noticeable, and I assume you will/have changed the forks at some point to a longer fork, which resets the head angle anyway.

    It's an 09 frame so has a vertical style shock rather than the latest horizontal style shock.
    I have RockShox Revelation forks running travel at 140mm.

    What about mounting the shock? Would I have to purchase new bushes washers etc a new shock wouldn't come with specific Spray mounts.

    You'll need to get a new DU bush for the top (standard fox) and move the needle roller over for the bottom. You might find it easierto get your LBS to just put 2 new DU bushes in and buy new tophats.

    Go to the BETD Goldtec site and look on there. Or you could call them and explain what your doing and they will advise you on everything you need.

    Easiest to get full mount kits probably so 2x

    In Heavy-Duty Mount Kit,12.7mm, M8x22 plus the tool would be best (or the Betd equivalent)

    If your shock is just top hats and bushes, you could just buy 4 x red coated DU bush in 12.7mm from TF Tuned and press them in yourself.
