This year, with team 610, we are using vex treads on our manipulator.
However the problem is that sometimes when we handle the tubes, the tread breaks.
I was just inquiring if any of you know a company that sells solid / sturdy tread (with links) made from plastic or metal?
In addition, check to make sure your gears or drive sprockets do not have excessive runout. That can cause excessive tightening of the chain or belt which might not be obvious unless you run the drive manually and check tension periodically as you do this.
