Does the Kinetic Bike Trainer work with a Shimano Nexus 3 Speed Hub?

Yes. But only when you take the following steps:

1. The Shimano Nexus 3 speed has an external shift pod. This needs to be removed in order to attach safely to a Kinetic trainer. To remove the shifter pod put the bike in 3rd gear. Loosen the set screw on the top/back of the pod (Philips screwdriver). The pod will “pull” off the hub assembly. What remains is a flange nut and push rod.

2. An Internal drive cone cup adapter must be installed.
