    Ok so ill start by admitting im going to sound completely stupid here so forgive me.

    Im trying to take the front wheel off my 06 Sprint ST 1050 (Non ABS),
    mudguard off
    calipers off
    19mm hex bolt inserted
    hold wheel
    turn
    the entire spindle rotates at both ends

    i know im missing something obvious but for some reason ive head the biggest brain fart and cant for the life of me work out what it is!!! :mad:

    Feel free to berate and abuse but help is MASSIVELY appreicated.

    Not sure if it is the same arrangement as the 955 but if that is the case the RH fork is threaded so the spindle needs to be unscrewed

    They are there to stop the spindle undoing itself when you dont want it to :eek:

    ok so ive put the frojnt wheel back on and all 'seemed' ok.
    Now im getting a knocking at slow speed which turns into a very small vibration at high speed.
    At slow speed its quite prevalent and 'knocks' the steering to the left slightly, not enough to affect handling but enough that i notice it.
    Im going to take it all to pieces and re-install at the weekend, was just hoping that someone had somewhere or something i can point the finger at?

    The spacers in the front wheel are a different size, did you put these back correctly?

    Im 99% sure i did, when i took them out i put them on the floor on the side it goes back in on.
    Is there a way to distinguish which one goes where?

    I am not sure which goes where so not much help on that. Mad dog had a site with manuals on it but cannot find the link, perhaps he will be along shortly to help

    Make sure your brake calipers are centered and are moving freely. Also, make sure the disc bobbins are moving freely as well (assuming they are floating)

    Found the link now, Mad dog has kindly put up the workshop manual for the 1050 at

    This extract from the manual may help as well

    I use a large flat blade screwdriver that fit inside the bobbin, then spray brake cleaner until the bobbin starts to rotate freely.

    This looks like my symptoms, he describes it better though.
    Thanks for your help.

    Yeah I downloaded the manual when I joined. I always like to have it next to me for reference, cheers.

    I'm struggling to find a bolt to fit through, how 'snug' does the screwdriver have to be? Do they spin loose like a wheel or do they need a bit of effort?

    The screwdriver blade goes inside the bobbin (where you would put the bolt in the video example) and has to grip the bobbin. If it can't rotate the bobbin easily, then spray brake cleaner between the bobbin and carrier until it starts to rotate with the screwdriver. Under no circumstance hit the bobbin to try and free it, or you will bend the carrier and/or disc.

  20. Buy a nut and bolt that fits through the bobbin, tighten them up and rotate the bolt until the bobbin spins freely. Sorted.
