I'm considering buying a Kona Rove ST bike with a 1x drivetrain setup. However, one concern I have is a limited range of higher gears (40:11 ratio for the highest gear). I would like to have some more range there, and would consider replacing the front chainring for a bigger one. Of course that would present a new problem in lower gears.

That could be solved with replacing the whole cassette or installing an expander sprocket, and I prefer the latter because of the costs.

The problem I have is with the specification, or lack thereof, for the SRAM PG-1130 cassette on the Kona. If I understand correctly, it fits a Shimano HG hub standard (?) and differs from the SRAM XG line.

In that case I should be looking at extender cogs designed for Shimano 11 speed cassettes?

SRAM PG-1130 cassettes fit on a Shimano HG freehub body, not the SRAM proprietary XD driver body.

If you see 11-42t cassette fits 10 and 11-speed non-XD™ driver bodies in the description on the SRAM page that means HG.
