I have a nexus 7 internal gear hub wheel with a back paddle brake. If possible would like to swap it out with an roller brake that i already have laying around.
I read conflicting information about if this would be possible or not with some saying absolutely not and other saying yes, just swap over the module so i can someone give me the right answer? It's an SG-c3001 (the updated version)

No. Different shell on the hub.
