Got the bike out today for a ride to a mates 3miles away on the road and thought I would take advantage of the travel adjust. I turned the blue know 2 clicks and pushed the forks down to "lock" them down to 100mm. Got to the mates 25min later after jumping off a few curbs to realise the forks had extended back to the full. I thought nothing of it and had a cuppa and a chat. Got back to the bike to go home and thought if I just push the forks down they will adjust back to 100mm as before but they did not. I moved the dial back to 160mm and then back again to 100mm depressing the forks each time but no luck. I did notice that at the 100mm setting the rebound was really slow and then back to normal at 160mm.

My questions are many but first off:

1. Would perhaps jumping off a few normal curbs to my mates perhaps blown a seal? If so I had no noises or experienced no rapid rebound.

2. On my way home I popped into a LBS not my LBS but one I have used before and asked what they thought. I was told that the travel adjust knob shuts off a little valve that only allows the travel to go so far and that I may have blown an o-ring more than likely or perhaps a one way valve. The chap was not very sure.

3. I have had them about a year and not done many miles c100 and today for the first time gave them a service and noted that there was not as much oil inside as I put back so was wondering if this could be the problem..I have not yet reassembled the bike so can’t answer the question myself but thought low oil may be the problem but then why did they adjust first off on my trip to the mates.

4. Anyone else have this problem before.

Many thanks
