I would like to add bar end shifters my my wifes 87 Bianchi Brava and can get new Shimano 8 speed/friction bar end shifters for $60, all needed parts included. Right now the bike has Suntour Sprint derailleurs and down tube shifters. I bought the bike new way back when and then kids and jobs etc. kept the bike virtually unridden untill recently. She is not a strong rider yet and I think it is safer to keep her hands on the bars while shifting. I have just put a nice set of old campy wheels with an Athena 126 mm threaded rear hub on it and have a new 28T 7 speed freewheel on order.
1. Will the Shimano bar end shifters index-shift with this set up?
2. If I were to buy a long cage rear derailleur, will either a Shimano or Campy 8 speed (or earlier) rear derailleur work with the Shimano bar end shifter indexing?
Many thanks for any info.
