why does my front suspension have no spring or air valve I am riding a old rally mtb the fork is a xc100 , I can find no mention of these online, and it has never a spring nor a air chamber to make the suspension work. it is recently began to stop working so I wanted to tune it. however I am lost as to how it works.
any ideas would be most useful.

many thanks

i had one of those some years ago. you need to check for bolts in the bottom of the legs, if there are not any you must get a long 5 alen key (about 45 cm length) take out the upper caps and introduce the long key. once you take out tha bolts in both sides you will be able to disasemble the fork, then clean averyting, grease, and put everyting together again.
