have a RX810 crank on a Topstone with mix of other 10 and 11 speed components
and the drivetrain is relatively quiet (when using both small and large chainrings)

R7000 crank would be an option (and a significant upgrade compared to RX600 crank) - but small chainring would 34t or 36t (compared to 30t of the RX600 crank) ...

what cassette are you using ? could use an 11-30 or 11-32 cassette ... 34-32 low is fairly low (approx 28 gear inches) ... ???
