I'm a fairly inexperienced (and out of shape) rider who has recently moved to Seattle, a very hilly area. I used to ride a Fuji Traverse (hybrid) in my original hometown, Tallahassee (which also has some hills). The Traverse had a triple chainring, and I found myself using the granny gear a lot on hills. In fact, I'd even sometimes switch down to the big climbing ring in the rear on steeper hills. (Edit: Checking my Strava, it looks like these grades were 7-8% on average.)
I'm buying a new bike now that I'm here in Seattle, as I didn't bring the original with me. I'm looking at entry-level road bikes, but these bikes tend to have double-chainrings. I am aware that triple chainrings usually have gear ratios allowing for an easier time with hills.
Should an inexperienced rider facing hilly terrain buy a bike with a double chainring, or should they always stick with a triple?
