Yup, gonna echo a lot of what Brendan said.

We ran our chain in the 2x1 tubing after being inspired by the local experts 118, and were extremely happy with the results. The drivetrain was probably one of the best we've built yet, and we had exactly 0 issues with it during the competition season. And the best part was we didn't have to do any real maintenance on it.

As for the installation, we just put the chain together (no masterlink), put the sprockets on the chain (not fixed, just loosely held by the chain), then dangled it into the tube as we put the shafts in place.

Worked great, 10/10, will probably run again!
