I have a specialized 2020 turbo lev. I’m thinking about upgrading to a 12 speed 10-50 in the rear cassette. It’s super steep in sections here in Colorado and I know it will assist in increasing battery range. My friend has an older 500 watt specialized and keeps the same (or close) battery range due to his upgrade on the 10-50 cassette as he spins faster. Any thoughts Appreciated
