FAQ

Does this shifter work with a Shimano Alivio 9-speed derailleur?

No. CUES LINKGLIDE technology uses a different cable pull ratio to older Shimano 9-speed groupsets.

Can a standard 9-speed cassette be used?

No. Shimano recommends using a CUES-compatible LINKGLIDE cassette to ensure correct indexing.

Is this shifter suitable for e-bikes?

Yes. The CUES range has been designed to offer enhanced durability, which is particularly valuable on e-bikes that are subject to greater drivetrain stresses.
