@Waxingtonknee@mastodon.org.uk What do you mean by "traditional" gears? The Alfine you mention is an internal gear hub which some may consider a not traditional!
Is it possible you're referring to the shifting mechanism? For example, indexed (click) shifter vs twist shifter?
Enviolo hubs are continuously variable transmission. I have had a bike shop offer to install indexed shifter when I had issues getting used to the CVT on my own bike.
