I have a bike with 9 speed brifters that needs a new rear wheel. I have a 130mm rear wheel with an old school 7 speed shimano hub and cassette body which I'd like to use on that bike. The wheels and hubs are in good shape but Shimano 105 hubs came on a 1991 bike.
I think these are my "best" options:
(1) Get rid of the brifters and use a pair of 7 speed bar end shifters. This is easy and "zero" cost other than labor.
(2) Keep the brifters and run 8 on the back with the 9 speed spacers. I have a 9 speed cassette which I can modify.
(3) Keep the brifters and get a 9 speed cassette body. I'll have to source a cassette body unless if I can find a crashed wheel or old hub from the local bike shop.
Are there other options I should consider? Are there any issues that I need to think about with any of these three options?
