Rear Derailleur Shifting Issues... Trying a new missing link...

Bought some new missing links.

This one is for 10 speed Campagnolo chains.

It's slightly more narrow than the Shimano 10 speed version...

This one is for 10 speed Shimano chains.

Made in Taiwan.

Shimano on the left & Campagnolo on the right.

It's difficult to see but the Campagnolo version is a fraction of a mm narrower than the Shimano version...

I tried to install the Campagnolo version on my bike with the Shimano chain & it won't fit!  That fraction of a mm is just enough to keep it from going on.

So, I installed the new Shimano version missing link on the bike.

Will test ride it tomorrow to see if it makes a difference...

 

Rear Derailleur Shifting Issues...

The bike's still not shifting right.

The "missing link" or "quick connect" link is in the red box.

The green box shows one of the normal links in the new chain.

Not sure if there's too much play in the missing link.

One think I thought of trying is to reverse the missing link.

This is how it was, as installed.

Tried reversing the link but it didn't make any difference on today's ride...

On the bright side, at least my "half-ass" repair for the bike shoe is still holding up (3 days now...).
