Bob is ok, he just takes some getting used to

yeah, maybe the lizard skin is too thin, I might try putting some kind of material under the skin on
the bottom and see if that helps.

You will bob more by doing that but you won't blow out your compression and rebound circuits. Try a
bit more air pressure in the main chamber to stiffen up the spring. You want to adjust the rebound
(the speed at which the suspension returns to normal position) so that it isn't so fast as to buck
you off and isn't so slow the shock packs up after repeated hits. You adjust compression dampening
(the amount of force it takes to get the shock moving) to get the ride feel you are after. Stiffer
less bob or plusher more active.

If pedal bob is a serious problem for you then you may want to upgrade your shock to a Progressive
5th element Air shock. You can dial in the amount of force it takes to make the shock react. Meaning
it will resist pedaling forces but still react to bigger hits from below. It's pretty cool, the ride
feels locked out until you hit a bump the shock just sucks it up and settle back into it's deadband.

Do you have any float in your cleats? That makes a big difference to me anyway.

You have to be smarter than a robot to reply.

Shift it into big-big just to see. If the rear derailleur isn't *almost* stretched out straight, you
could safely take out a link (or maybe even two).

There'a also a screw (B-tension?) that can move the der. cage a bit farther from the swing-arm; that
can reduce noise quite a lot.

Since no one else mentioned it (that I recall at least), you might just have your shoe(s)
laced/strapped too tight.

That's about what I think of as normal in my Isis. OTOH, on one of the few rides I've every done
with somebody else on an FS, the other guy remarked at how amazingly little bob my bike had.

Recently I switched from a Fox air to a Romic. About the same amount of bob most of the time, but
now, when taking long slow strokes out of the saddle on a hill, the Romic doesn't move at all. The
Romic feels better overall though - although I can't articulate why.
