Updating an old Miyata 110
So I have this old Frame/fork + derailleurs, shifters, brakes, levers, bottom bracket, left crankarm, and seatpost.
BB and headset turn real smooth, and the brakes and shifters work fine. No rust and the frame seems straight. My 700c wheelset I want to use on the bike fits fine. So I'm good to go. I'd like to build it up with everything I have in my garage, since the main reason I bought it was to use as a platform for some old parts I have that I'm not using and which I'm too lazy to sell.
I'd like to run it as a 9 speed.
The thing is that if I put on my rear wheel with a 9 speed cassette, the rear derailleur doesn't quite line up with the largest and smallest cog. I'm not surprised. The bike probably came as a 6 or 7 speed at best.
What's the limiting factor? If I put on the 9 speed Ultegra rear derailleur that I have, will the shifters be able to pull it across all 9 cogs? Or will I need different shifters? If so, I have some old suntour barcons. Will those work?
Finally, if I remove the largest cog from a 9 speed cassette, could I run it as a 7 or 8 speed with the current shifters and derailleur?
