I'm just saving and restoring a Miyata bike from ca 1990. I think the model was called Sport Cross but I cannot find it in any old catalogues. I find the model but the info doesn't quite match up. For example I can find a Sport Cross from 1991 but that one is with 700c wheels and mine is for 559 wheels.

It's a butted steel frame and all I know is that the fork is CroMo. The stickers on the frame is too worn out too see.

Any ideas?

    I doubt that;s the original handlebar - looks way too wide for the period.

  • Koga Miyata, or any bike with Miyata tubing?

  • I think the only thing original is the frame...

    Looking again the rear brakes look like V brakes but there's a center mount which would have been for cantilevers. Nothing wrong with that upgrade, but rear brakes are certainly not original. I suspect the front hanger was lost/removed when the bars were changed.
