A few months back, Velo Cult had a bike swap meet and I scored a pair of Campy 8 speed brifters. I thought those would be rad for a bike I hope to build for my wife ('82 Trek 610). She's pregnant so building her bike takes a back seat to all the other things I need to do for the baby and my own cycling needs.
Fast forward to today: I've been realizing that Campy 8 speed rear derailleurs are rare as hen's teeth, and costly.
I have the followings bits and pieces that I hope to use in the build. Can anyone give me some input on an affordable way to get this all to play together (remember the baby that I mentioned? oh and the wife, too. she's also expensive):
Shimano compatible wheelset with 7 speed cassette
SRAM 8 speed cassette
Wheels Manufacturing Shimano --> Campy 8 speed spacers
I know I need a rear derailer, but in the interest of economy, should I just leave the 7 speed cassette in place and get a Shimano 7 speed RD?
How can I affordably cobble-togther, or jerryrig this contraption to a point of happy indexing for my wife, the mother of (soon to be) two children?
From my reading using the 8 speed Campy brifter on the ShimaNO 7 speed cassette will be fine, just with a ghost shift.
Again, no offense to C&Vers named Jerry.
PS Her birthday is the 24th. Would love to have this thing all set and dialed-in in time for that!
