Wow, interesting mod. I've added a longer B-Screw to derailers to get a
little more spring tension, not the most elegant solution, but no need to
take the derailer body apart. I'm interested to hear how it goes if you do
take it apart. Good luck.

I've got an old Atlantis w crazy chain slap. I can't look at a stick on
the road without the chain slapping around. The gears are always slipping
on the rear as well. Drives me nuts.

With the clutch on, shifting the chain is tight moving onto the big front
chainring of 52 while the rear is in certain positions, plus, to remove the
wheel the clutch needs to be turned off anyhow, so I just left it off.
Next ride I'll test it again. The largest practical rear is 28 on my
setup.
So according to the drawing , *if* there's a 2nd hole for greater tension ,
it will be in the Outer Cage Assembly (part 10) ...which would allow the
cage tension spring (part 9) to be wound up more.

Just so we know what we're talking about, here is the exploded view.

There is a spring that runs the body (2), and a spring that tensions the
cage (9).
As a Mechanical Engineer, if I had two of these, I'd take one apart just on
general

That's a great suggestion ...I didn't even know that was a possibility
I'll look into the stronger springs

I would suggest replacing the spring with from an XT or XTR. You can get a
new spring for $5 or so.
When I had too much slap and occasional thrown chain from an LX (which
worked fine otherwise), I switched to an XT derailer and the problems
disappeared. I assume it's mostly the chain tension
Hi Ken,
I'm curious. Why do you leave the clutch de-activated? Are there downsides
to using the clutch?
Thanks

I changed my derailler to one of the newer Shimano shadow; it has a clutch
switch, but I leave said switch off and it still provides more wrap and
tension than my older derrailler. It's not rapid rise thouigh. I'm
running 30 34 52 in front and 11-28 in back. 9 speed.

Hey J.
I'm interested in this. It sounds like a DIY derailleur clutch.
I Google searched that and got some promising hits.
If you dive into this, please share.
Thanks
Trying to stay on task in San Diego,
