I am converting the the Koga Miyata to 8 speeds with Shimano R400 downturn shifters on Retroshift brake levers. They have no friction mode though.
I bought my Shimano eight speed bar end shifters, three pair were new over a decade ago. Later bought a fourth pair as a backup in case I need them later on Ebay.
I know nothing about eleven speed hubs.
Shimano made two different eight speed bar end shifters. One pair were for Dura Ace and the other for everything else. They are not interchangeable. You would want the ones that are model BS64, they usually have a label that says Not compatible with Dura Ace rear derailleur.
