Hello. I'm about to put SunTour Accushift 7 speed bar-end shifters on my wife's Austro-Daimler Puch Pacifica.
The bike does not have downtube braze-ons. I have a nice set of 7 speed bar-cons from ebay that I want to use with an accushift rear derailleur and a 7 speed Winner freewheel or 7 speed Powerflow cassette wheelset for 27" that I intend to have built.
I notice that newer bikes with brifters have the adjuster barrel on the rear derailleur and also at the headtube or down tube. Do you need 2 of these adjuster barrels, or can you get by with just the one on the rear derailleur?
I thought about using a down tube stop like this: http://cgi.ebay.com/ws/eBayISAPI.dll...7468&rd=1&rd=1
But if the mechanics in the house think I should have downtube adjusters, I may modify some downtube shifters that clamp on, and fit them with STI adjusters.
Thanks for your assistance with this retro project.
