I'm finally on putting the finishing touches on a commuter I've been working on for the last few months. Since its been a budget build, I stuck a set of tiagra brifters with a broken thumb shifter for the front, so I'm just going to run it as a 1x9 for now.

In short then, I need to find a good gear ratio for it. I only have one moderate hill I'd ever tackle and besides that its mostly flat in the valley I live in. What would you all recommend? I'm running a 53 tooth in the chainring
