Extended Range Cog

No one disagrees with you: those massive, steep climbs are lame. Don't try to find the long way around, though, and by all means, do not get off and push. Slap the e*thirteen Extended Range Cog on your freehub body, and go for it. You buy yourself precious extra gear-inches with either the 40- or 42-tooth big ring back there, making even the worst uphill grinds a bit more bearable, if not possible, where they once weren't. The world of what you think you can ride will expand. Only compatible with 1x drivetrains.
