Thanks for the insight Garth! You're totally correct of course, Riv should be checking this stuff. I've already talked to them about another quality issue I had with the frame, and they took care of me with that, so I didn't want to keep complaining, but I should let them know. I'll take some measurements and figure out how oversize it is first. I've been a fan/supporter of Riv for a very long time and to have these issues on my first frame has been a bummer for sure, but I'm confident they can be fixed.
