The first Catek bindings had a ring that was really thick and left an air gap under the bolt area of the base plate. . I never understood this because it facilitated insert suck but you were, in fact, riding on the rubber.
Catek changed this with the OS1 which basically has a thinner rubber ring and allowed the body of the bindings to contact the board. I believe there was less than 1 mm of air gap which again aided in a very small amount of insert suck until the 2 made contact. The rubber rings on the OS1 only did anything as the board bent into it. Once they added the Polycarbonate sub plate, I believe this ring did virtually nothing. After riding both I feel no difference at all.
As far insurances go I’m looking into it.
