Hello,
I am trying to fix up my 1991 Miyata 721 and part of those repairs involves the shifters. The old shifters broke off and now all there is is a simple hole thru the downtube of the frame without any kind of threading. I got some new downtube shifters (Shimano SL-A500) but have had no luck finding the bolt-on bosses. I've also looked at getting some clamp on shifters but most look to be 28.6mm and mine roughly measures to around 32mm.
The shifters should look like this: https://simplicityvintagecycles.files.wordpress.com/2016/05/miyata_721_05.jpg
Thank you all.
