7 speed downtube shifter to thumbie/trigger conversion?
I just picked up a Giant Perigee, 1994 I think, with Shimano indexed 7 speed downtube shifters and Shimano 300 rear mech. I am converting it to a flar bar 1x7 commuter. Will any Shimano 7 speed thumbshifter or trigger set work with this setup? Specifically I have thumbies from an old Bridgestone, Acera I think.
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
For the rear shifting (all you are concerned about) any 7-speed Shimano indexed shifter will work with any index-compatible Shimano rear derailleur. Obligatory caveat: pre-9-speed Dura Ace is the exception. Not your problem.
