Changed the stock air shocks on my 12 street glide to the Premium Hand adjustables (both 12") and found them to be superior in every respect.

You can feel them using the entire stroke, and small bumps are easily absorbed, and sharp bigger bumps are much more comfortable.

The handling is much improved. The skittering you feel going around corners with the air shocks is gone, and the bike tracks much better.

Only complaints I have heard about these shocks it from very lightweight riders who feel they cannot be soften enough for them.

Super easy to adjust when riding double or loaded up. A simple click **** on the left side rotates for carrying additional weight.

I believe the Ohlin and other high cost shocks might be even better, but they can be a pain to get adjusted right.
