GEARING

[ARCHIE998]

I have a 2021 Giant Explore E+2 STA (E-bike). It is a 9 speed Shimano Alivio gear system. Can I upgrade it to a Shimano Deore 10 speed? Will the extra gear cog on the cassette be to wide for the rear frame? Also, will this be a problem for the Syncdrive Life firmware? I got nowhere with Giant tech support……..thanks
