I have a similar question as the OP.

Just got my first analog SS (State Bicycle Black Label), after coming from road, mtb, and a SS E-bike (Ride1UP Roadster v2 - brilliant bike, with the motor assist helping with the 64x20 gear up climbs).

Only have had the SS State BL for less than a month, with a 48x17 freewheel set-up, and really like it. Just about the sweet spot for me, for standing up climbing and fast enough flats/descents. So far, have done 20, 40 and 60 mile (with 3000+ ft elevation gain) rides. Finding that my average speed is down though, with the SS gearing just not enough to keep up with the roadies.

Question: has anyone done 80+ mile rides with let’s say 8000+ ft elevation gains, with their SS? I’m thinking for that kind of ride, IF I were able to make it, might require a 48x19 or 48x20?
