The Brother Cycles Big Bro is one of our favorite all around touring and bikepacking frames.

Sliding dropouts give you the option to vary chain stay length, run as singlespeed or with a Rohloff or IGH.

Lots of mounts for attaching racks and cargo, and very generous tyre clearance.

It very nicely straddles the divide between a very capable touring bike and a mountain bike.
