I am trying to take the forks off my girl friends bike. Usually the forks drop out after you remove the bolts on the stem.
This headset seems different can anyone tell me how to remove the compression ring?

Many thanks in advance

    screwdriver and a soft faced mallet.

    the ring needs lifting to release the lock.

    I would tap the top of the fork steerer with a mallet (with the fork off the ground of course. This should force the fork down a few millimeters, then, by pushing the fork back up again, you will see the compression ring rises from the headset, releasing the tension and allowing you to remove it.

    If you dont have a soft mallet (plastic ones are normally available from cheapo stores for a couple of quid) you can use a piece of wood as a drift to prtect the steerer and an ordinary hammer. Never use an ordinary hammer face direct on the steerer.

  • I know this is an old thread but has anyone managed to get one of these dis-assembled? I have tried with the drifting method but cannot move the steerer post down at all. The gap in the compression ring is too small to insert a strong enough screwdriver.

    Method above always works if it doesn't just lift out, but you could try giving the front end a bloody good shake to loosen everything up.

    The method above worked for me, try hitting it a bit harder
  • Managed to do this over the w/e by hitting it with a lump hammer; one quick tap was all it took. Using the wood reduced the impact and would not shift it. I do not recommend this method but it worked and did not damage the tube.
