    Hope Head Doctor

    What is the torque for the 8mm hex bolt inside the steerer tube?

    How deep inside the steerer the head doctor must be?

    What is the torque of the stem cap preload bolt?

    You can read the Hope instructions here. (pdf). Hope provide downloadable technical documents for most of their products.

    They don't say anything about torque

    "They don't say anything about torque"

    "...tighten the wedge until it is solid in the steerer."

    Further to this, there is no predetermined torque for top-cap bolts because you are using the bolt to preload the headset bearings. As the Hope instructions say, you need to tighten the bolt until there is no play felt in the headset bearings. Just read the instructions again, it's all perfectly clear.
    Whilst I can see the benefits of using a torque wrench, the skill of being able to personally determine whether or not you've torqued something correctly is infinitely more valuable.

    10-15mm inside the steerer tube,nip the bolt up tight enough so it wont slide up the steerer when pre-loading the top cap.

    tighten the top cap bolt until there is no play in the headset, the idea is to pre-load the headset bearings just enought so that all of the play is taken up, check the that there is no play again after a couple of rides because some headsets take a little time to settle in, especially hope as they have quite a few components
