Atoc's non-pivoting system works with recumbent bikes, and single bikes, and features:
No contact points to damage your bike's finish
Fits most roof rail systems: Yakima and Thule compatible mounting clips come standard.
Only 5 1/2" wide ... which means you can carry lots of bikes (or other stuff) on your rack, too.
The BT-76C includes a quick disconnect tail section, fits bikes with a wheelbase up to 76" with a minimum load bar spacing of 22".
A breeze to install!
