    Going from a (6) 7 speed to 9 speed

    Just picked up a 1990 Miyata 600GT off craigslist and had a question. I think I answered it but wanted to double check with the experts.

    The stock Miyata had a Suntour 7 speed. This one has a 6 speed, not sure what kind. I was thinking of upgrading it to a 9 speed. I measured the rear axle spacing and it was about 130 mm. If I were to get a new wheel set (the one on it is pretty bad) and get a 9 speed cassette, it should fit, right? Of course, I'll have to get new bar end shifters since the ones on the bike are indexed for 7 speed.

    Also, will the stock rear derailleur (Suntour XCE) work with the 9 speed cassette? Or will I have to get a new rear derailleur?

    New wheel will probably fit. Derailleur may work, but you might find a new one will perform better.
