I am looking for Shimano Nexus or compatible gear shifter that can work through or via left hand. I am thinking of this grip Amazon.com: Shimano Nexus-Revoshifter SL-8S20 Right Shifter - 8spd Black: Sports & Outdoors. But I am not sure if this will work back wards towards installing in the left handle bar. Any suggestions is greatly appreciated. NOTE: My Nexus hub is an 8 spreed inter 8 premium edition http://www.amazon.com/Nexus-Inter-8...e=UTF8&s=sporting-goods&qid=1260738028&sr=1-4 that is also compatible to Nexus Alphine Amazon.com: Shimano Alfine SGS501 32h Disc brake 8-spd Internal hub Black.: Sports & Outdoors.
