FAQ

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

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

Can I use a conventional 9-speed cassette?

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

Is this shifter suitable for electric bikes?

Yes, the CUES range has been designed to offer increased durability, which is particularly appreciated on EABs subject to greater transmission stress.
