I am in Manchester CT if you live locally.
20 inch AlexRims DM18 wheel with a Shimano Alfine generator hub model DH-S501.
This is a 35-406 (20") wheel.
Rim brake style.
It spins true, bearings are great. The wheel is in very good condition. This can be used with any 6 volt light. See the picture that shows the plug style.
Used on one 400k ride and a guided tour through Death Valley in March 2018.
I have not used it since then. I no longer need this.
