6) Are the release pucks any different?
The release pucks are identical to the previous versions.
7) Will I need new racks?
The racks are identical to the previous versions. If you have ever had Zega cases without any exhaust cut out on your bike, the new version will fit great. The Zega rack is extremely strong with multiple mounting points along the bikes subframe, distributing weight evenly.
8) Do they come in the same colors/finishes?
The new version is available in the same Bare Aluminum, Silver Anodized, and Black Anodized finishes as before.
