enter image description hereI 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

    Presumably rally is a misspelling of Raleigh. And the fork is made by Suntour? If its a cheap fork, chances are it has a spring and it isn't designed to be user serviceable, so taking it apart and repairing it will be somewhat of a challenge. – Batman Nov 18 '15 at 17:26
  • hi thanks I am unaware as to the make of the for. but thank you for you point. its a bit of a shame as it has gone from 100mm of travel to just 40 – Ewen Shackel Nov 18 '15 at 17:28
  • What about the model of the bike? – Batman Nov 18 '15 at 17:34
  • not a clue it was purchased of eBay. I estimate it to be around the 90's if that's any help – Ewen Shackel Nov 18 '15 at 17:36

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.

  • Hi as a sub question what type of grease would u recomend? And would something like wd-40 work – Ewen Shackel Nov 19 '15 at 6:53
  • @EwenShackel I wouldn't advise WD40 anywhere near a bike. It is primarily a DE-GREASER, which means its very effective at reducing lube. – Aron Nov 20 '15 at 7:09
