this prompted me to actually test my assumption about the SunTour chainstay stop, and Mea Wrongio! I don't think ST ever intended the curved lip on the top edge to actually capture a spoke head cause that doesn't work very well, plus never saw any matching bolt-on bit end for the threaded spoke ends.

The (typically brazed-on) bits that DO grab-hold and permit tight storage of 2-4 spare spokes that work as chain-slap protection have distinct slots for the spoke heads, the ST stop is too slippery.

And speaking of poor performance by design: when correctly positioned it's really too far back on the stay to really help much since most chain slap occurs in the center of the chain-run where "bounce" is most pronounced! Nice try, Sun Tour.

On to next hobby horse: I've seen Falck (associated with the Mannesmann tubing international combine) spelled "FALK" but only on this style of tubing sticker. I'm sticking with "FALCK" since that's how it's spelled 90% of every time it appears in print. I think the artist who made this sticker art just couldn't spell (too 'creative' for such mundane stuff!)
