If your going to state something please try to state it correctly. Bob Gordon was who Robby claims designed and built IBS before anyone else. It’s said the Blazers had a form of IB, which I had no idea and is really cool. Im curious if they are still on the one Vessels has? Then “Betsy” Chenowth buggy and the clone buggy Robby drove had the modern version of IB with the fluid controlled flapper valve. This is the buggy Robby claims Marking got to see the shocks on, and then took the design to Fox and created the patent on that design IBS
Mickey Thompson’s Challenger was the first to have external bypass to everyone’s knowledge. That was built by Rick Hasselo in Mickeys shop. So no clear definition if it was Mickey or Rick who thought it up. Rick eventually started making external bypass through his Shock Tech Co. which Rick limited who he would sell shocks too. And it wasn’t about who was popular, had deep pockets. It’s who Rick liked.
