ya, 48/31 and 11-34 (not that odd, as road cranks have been 50/39 and 50/39/30 for ages and ages.)
but lets face it kids, 48 is still overgeared, but this bike is clearly aimed at the strong and fast crowd hammering it with the guys. .....
My road bike came with compact double, 50/34.
I can see some committee sitting in a meeting saying, if it is gravel we should drop the gearing lower than road gearing. Some say no, those that say yes can't agree how low. The one in charge of the meeting says, corporate wants an answer by 4pm. They all compromise at compact double as the base standard but drop two teeth on each ring. And none of them ride a bike except for occasional family outings. That is how important decisions are made by people that have no business making decisions.
I know a couple hard core roadies that bought gravel bikes in the past two years, they ride them on pavement but on rare occasion one of them will ride it on gravel rail trail. Marketing told them to own gravel bikes, so they complied.
My road bike came with 13/29 Campy cassette. I like having a downhill gear, I learned that Miche made a 12/29 that fits on my Campy hub so I bought that to slightly increase my highest gear for the occasional long shallow downhill. Yeah, I only ride that on pavement, so should have road gearing. I use that as an example, sometimes a high gear is nice to have.
