let me know if you need the bike binding straps. I think I have a set for two bikes (two per bike).
Or you can go to a bike shop and pick them up for a few bucks each. I think Thule makes them. They have those rubber fastening straps like you would see on the pedals of a gym exercise bike.
The Bird rack worked well. You just have to get used to the flexing when the bikes are on. Always make sure those harness straps are pulled down tight. and be careful not to drop the anchor hooks on the trunk lid.
Man I really want that Saris Thelma bike carrier. Maybe Bird will incorporate it somehow.
Willwood never responded to my inquiry.
