Any opinions on how hard it would be to mount a Rohloff Speed hub to a Novara Safari?
Assuming the Novara Safari uses vertical dropouts as pictured, you can use a Rohloff Speedhub, but you will need a special kit, because you will have to use a torque arm and need to use the external gear mechanism with these style of dropouts.
Visit the Rohloff site, and its autoconfig utility will point you to what you need.
