Re: 2x1x1/16 Belt-In-Tube
The combination of 9mm wide belts and 24T pulleys, especially with 6" wheels, has been tried in FRC before by several teams with problems. Ratcheting and tensile belt failure are among the issues teams ran into.
My old team has done belt in tube for several years, eventually settling on 24T pulleys and 15mm wide belts, inside 3x1.5 tube. The 3x1.5 is used to leave clearance for rivets above and below the chassis, so if you attach your chassis differently you could use a smaller tube.
Using an adjustable tension system rather than exact centers presents some challenge as well - you need to get the tension exactly right. It's very possible to over-tension the belts, or tension one side more than another, leading to issues. So be sure you do this right. That said, once you get the tension perfect, it's going to stay that way if you did it right.
