    I have had a Saracen MTB since new about 15 years ago and have replaced most parts, including the freehub at least once. I am having trouble finding a replacement as the freehub has again worn out.

    Its a Shimano set up
    7 speed (HG50 - 7 cassette)
    Hub is Shimano Deore LX FH- M550

    Can anyone suggest where I might get a replacement ?

    Thanks Dennis

    I'm not sure what the sourcing problem is ...

    Shimano Freehub bodies are readily available, BUT the price is generally greater than the price of a new hub!

    However, since almost all Shimano Freehub bodies are interechangeable, I recommend that you simply cannibalize the Freehub body from a new hub for the one on your current wheel ...

    You need to be aware that there are currently two Freehub body sizes -- "compact" & standard.

    [LIST] YOU probably want to "borrow" the Freehub from an ACERA hub which I think will have a "compact" Freehub body; but, a standard Freehub body can be used, too, if you add a spacer to the end of the Cassette + possibly some other adjustments which may be more than you want to perform (e.g. redishing the wheel) ...

    FYI. There is a slight difference between some Shimano's Road & MTB Freehub bodies due to the type of cone & seal (i.e., the size of the open end), but I have not made a serious investigation of the difference.

    BTW. I have found that the hub from which the Freehub is being "borrowed" needs to be partially laced OTHERWISE it is almost impossible to get enough counter-leverage .... PLUS, I have often needed to use a "cheater bar" to get enough leverage on the 10mm Allen wrench which is used to remove the Freehub body's "hollow" bolt.

    Thanks for your help. I think I will just ask Chain Reaction Cycles to recommend a new hub and go with that. The old hub is on its third set of balls and is probably due for replacement after 15 years use ! In any case I will need to rebuild onto a new rim soon as I ride in an area with fine abrasive sandy mud that chews through rims every 3- 4 years.

    Thanks again
    Dennis
