Hello. In AUG 2017 you mentioned having installed an Altus derailleur Rear, and efneo Front, giving you 24 useable, perfect shifting gears on your Rover Tandem. I am about to purchase a Rover Tandem and want to improve my gear options also. I am planning on getting IPS. With the IPS, wouldn't the efneo on the front only affect the captain, and not the stoker?
Thanks for your insight, and how is the tandem working out for you since the changes you made?
