My 11 speed GX 10-42 cassette needs replacing, and I fancy a bit of extra range.
A Hope 10-44 seems to an option, but the feedback on the interweb is mixed with talk of poor shifting, incompatibility with Shimano mechs and SRAM chains, and high wear on the 3 large alu cogs.
Other options would be a E13 9-44 or Garbaruk 10-46, but both are not without their problems, E13 lumpy shifting and creaks, Garbaruk creaking, tolerance isssues and loosening of the lockring.
The remainder of the pack, Shimano, Sunrace and Box are giving away a lot of weight.
If Hope is not a starter, I am leaning towards an E13.
12 speed Eagle and XTR would both be better options but would require a complete drivetrain replacement, and are too spendy for the moment.
