Hey Keith! If you're looking for a set of Magura RT Aero Brake levers for your Cube Aerium bike, it might be a bit challenging since they're no longer being made. However, there are a couple of options you can explore. First, try checking out online marketplaces like eBay or cycling forums where fellow cyclists might be selling their used ones. Another option is to reach out to local bike shops or contact Magura directly to see if they have any old stock or alternative options that could work for you. Don't forget to consider upgrading to newer brake levers as well, as newer models often come with improved features and performance. Good luck with your search, and happy riding!
