Rear hub for randonneuring - any "classic" model?
super-reliable
not too heavy
low maintenance
not super expensive


Any Shimano XT hub M76X - M77X. Also confider the newer T7XX "touring XT" models.

Shimano hubs are exclusively (afaik) loose-bearing rather than cartridge hubs, so they're easily serviceable and the balls are available almost everywhere.

The XT range should also have decent seals, durable materials and not be too heavy.

XT hubs don't get hyped because everyone already knows about them.
