We have built a few Skyelanders with a Rohloff hub. We use the same sliding dropouts as we use on our Kibo Rohloff along with the Rohloff specific inserts. We have built Skyelanders with a Rohloff hub with both flat bars and drop bars. If a Skyelander with a Rohloff hub is what you're looking for then just drop me an email or give me a call on 07850 881438.
