42-42 is a pretty low bottom gear.only u know for sure but can't see you needing it much lower unless you're loading it with luggage or getting a second set of wheels shod with cx tyres and hitting the gravel tracks (which you possibly should) - it has the makings of a good gravel bike.
its not really about the 42/42 bottom gear, but also the spread of the other gears and the terrain you ride on, along with wheel/tyre size etc etc..............also i'm currently weighing in at 18st 11lbs and i live in south wales................the 1st 10 miles of my commute home from work sees me climbing circa 1200ft, which is a little over 100ft per mile and its not easy going after a day in work. yes the 42 up front is a pretty good gear, along with the 42, 36, 32 of the next 3 on the cassette. but when your trying to hawl ass up a long continuous climb of circa 3%, with the weight im carrying (circa 120kgs) it can be tough going......and makes it harder to recover for doing at again the next day
just for ref: my commute is a 15 mile each way trip........going in i start with a 3 mile climb with 250ft of climbing, then its all down hill for the next 12 to the office, but on the return its a different matter
lots of people on here complain about riding a 34/32 fully loaded.........and even when fully loaded their bikes weigh a lot less than i do
