Fork keeps developing play.
I have a Karate Monkey (threadless 1 1/8" setup) and the stock rigid fork keeps developing play over time. What I mean is, if I lock the front disc brake up and push the bike forwards and backwards, I can feel the fork shifting in the headtube. I have adjusted it several times but it eventually become loose again. I have a drop bar setup so I have the steerer tube left long with about 2 inches or spacers underneath the stem and another inch above as I haven't cut it down yet. I would prefer not to cut off the remainder as I like the room for adjustment but I wonder if having the bars so high might be causing the problem. Extra leverage or something? Any ideas or should I just keep adjusting it every few weeks? I dont want to ruin a headset or mess up the frame.
