I am building up a detatchable with 20" wheels and a Shimano nexus7 hub. Used it for some time already with the original BB + cranks for the bike but for sure the chainwheel was not right for the setup.
Now that I painted and put a modern BB I wanted to put the right size chainwheel and sprocket for it. Can not find this hub in Sheldons calculator. Anybody using it so I can put it right ? Thank you.
