I suspect you are right. I've also had the Argo out in those cold temps, but was thinking.......(Maybe that's a bad thing
)
The way the tracks fit together.......the plastic spacers have little fingers that fit into chanels machined into the Grousers. They are a nice snug fit, and in my mind I saw them flexing a bit as the track rolls around the front and rear tires. Not much but some. I was thinking this constant flexing might cause a problem, but after spending some time riding around now, and observing the tracks, I no longer believe this is an issue. I have a lot of confidence in UHMW Plastic, it covers the bottom of my Jetboat and I can tell ya, It's hit a hell of a lot more rocks, at higher speeds than my Argo ever will
