    Quick technical question. If a stem seems a bit tight when fitting onto the steerer column how much pressure should (or is it wise) to use to push it on?

    In actual fact, the bike in question is a bit weird; the headset is mounted upside down and it is the fork assembly that fits to the steerer column. So in actual fact it is the fork that I am having trouble fitting.
    I think that with a bit of force it will go on, but I don't want to do any damage. The fork is aluminium.

    Oh I saw one of those rattling it's way up Argyle Place earlier on, it had been fairly belting along Melville Drive (I was coming down the Leamington Walk)

    Druidh might have more elegant technique, but normally I would wedge a large flat screwdriver into the gap in the clamp and open it up fractionally to allow the stem/fork to slide on.

    Butter....

    Nah - as Arellcat says , a little extra tolerance would be gained by opening the clamp up a fraction. It might be worth checking that the steerer is fully round too (i.e. hasn't been damaged in transit).

    Thanks Arellcat and druidh. The fork is new to replace a previous cracked one, so I have been paranoid about doing damage.

    Managed to get it on last night. The screwdriver method worked, although I would have needed an extra hand or to to actually push the fork on whilst opening up the gap.
    In the end I reversed one of the clamping screws and used it to gently push the gap open a bit.
