I've had an ongoing problem with my Raleigh Superbe (1972). On a very intermittant basis, the fork will freeze up. When this happens I fall off the bike- it can't be steered. The fork lock has not been engaged when this happens but I am a loss at what it could be. I have concluded that its not worth riding the bike until I am dead certain that I have found the smoking *** on this one- so far I have been really lucky that this has not happened in a way to give me serious injury!
The only clue is that it happens when the fork is pointed straight ahead. Could it be something with the headset (the bearings in it are new)? if no, the fork lock is all that's left.
Anyone run into this before??
