    Hey guys and girls, the otherday i took my bike to mechanic to do a fork service. I would have done it myself but internal parts scare me and i didnt have the tools needed or the time needed.

    They rang and said that the head bearings need replacing, i said i dont have the money at the moment so they were happy to put it back together and do it at a later time. Problem i have is when i picked it up the forks were sitting lower in the trees than i remembered. I rode it home and it felt stiff to turn. When i got it home i measured it and it measured 25mm instead of 31mm.

    Bit of history. Im a newish rider who only rides 15 mins to and from work with the occasional long ride (200-300km). When ive gone on these long rides the steering gets heavy, not sure if me or bike. Before i took the bike to mechanic it started getting stiff just before i got to work (happening more regular)
    the bike has been laid down by previous owner but i changed the forks for a good second hand pair so they are straight.

    so my questions are should i raise the forks that extra 6mm
    Also does the stiffening steering indicate headstem bearing.
    thanks for your help

    yes ..... mechanics are useless

    yes ..... its needs to be replaced ..... it also may have been over tightened .... mechanics are useless

    it may also just need lube

    lol yeah they do seem to be a waste of time seeing as you need to check all their work and adjust most of it.
    i will replace the bearings myself, just need the special tool to torque it correctly.

    Should work ok.
    Ones I have made from a piece of pipe of the right size, cut on the ends as described and a nut welded to the top to fit a socket and tension wrench. Works well for the small amount of tension that is required.

    Sweet thanks mate. I have an old socket I'll be using that even has the 1\2 inch drive already catered for.
