I'm getting ready to order parts for a bike that'll use a nexus 8speed hub, and I have the choice of using a drum brake (which comes with the hub) or taking the drum off and using a vbrake. How much do drub brakes weigh? What is their braking power compared to vbrakes? Do they lock the wheel like coaster brakes? Is the pull compatible with vbrake levers, or do they pull like calpiper/canti brakes?
I searched for drum brake, but found nothing to answer my question.
