Gear selector says, "Adios!"

It tried to escape but it couldn't! 

On my 50 mile ride today after slowing down/speeding up I went to change gears and...nothing!  My left boot hit "air;" there was no gear selector lever!   WTF?   Turned out that the circlip that holds the selector lever on shaft had abandoned its position and the lever slid out/dropped off.  Fortunately, of course, the connecter that links the lever to the gearbox shaft kept the lever from disappearing in the dust.

I slid it back into position and kept my foot pressed sideways against the lever to ensure it stayed in position for the remainder of the ride - about 15 miles.

I'd like to claim that the circlip failed due to old age but I suspect that although it might be old age related, it's not circlip old age that was the problem.  A couple of months ago I had pulled the selector lever to clean/grease the fitting.  I THOUGHT I had ensured that the circlip was correctly installed in the groove when re-assembling but when given that the two possibilities are:  1. Failure to install correctly or, 2. Steel circlip failed due to old age...well, what do you think?  ::)

General advice here is to not re-fit old circlips when putting the gearbox back together.

 Sounds like good advice!!!   ;)

Could be worse. I once made the mistake of using a second hand circlip to refit my front sprocket on the Aprilia. Needless to say that was a bad move. The sprocket made a brake for it and locked the rear wheel solid.
