• Nope! I also thought about this, but my logic was, without washer and proper tightening, it gets loose in 10min. Without washer and with proper tightening, it will get loose in 1 hour. At the end the vibrations on the fork will get transmitted to the headset and race, and there's nothing to prevent it from turning... What do you think?

    I think you're wrong. I'm currently using a headset with about 30mm of untabbed spacers between the top race and the locknut and it's not given me the tiniest bit of trouble. Some people recommend filing the tab off the washer because, if it turns and jams in the fork threads, it then can't move up and down and it stops the race and locknut tensioning against each other properly.

    Filing a slot into the fork would be horribly difficult and likely weaken the fork. Buy or borrow a proper thin spanner for the adjustable race (you can't do this job without one), use a big adjustable spanner for the locknut. Put the tiniest smear of grease on the fork threads, but make sure the mating surfaces of the race, washer and locknut are clean. Then tighten them up against each other, hard!
