    Fork size question - threaded please help!

    Hi there!

    I'm about to buy a 1" diameter suspension fork replacement for the stock one that I have. I have a threaded headset and has a quill/stem is stamped 25.4" which goes in the fork and fits properly

    The new fork is 25.4mm / 1" in diameter

    Please guys let me know if the new fork I buy can replace my stock suspension mountain bike. The new one is 15mm longer which I think I can add spacers to it so I can use properly but correct me if I'm wrong.

    You shoudn't use spacers on threaded headsets ,the steerer tube should be cut to the correct lenght .One washer between the adjustment nut and the lockdown nut is the best option. Look at the Park tool site or Sheldon Brown foe more info.
