    New question here. Antique 7 speeds to antique 8 speeds...Is it doable ?

    I have an antique 1992 Klein Attitude(7 speeds) and I would like to update to a lesser antique 8 speeds Shimano CS-M900 XTR Cassette 12-32T. Is it doable ?
    I noticed the 7 speeds cassette spacing is shorter than the modern 9 speeds spacing.

    My plan is to make it to 1 x 8 speeds(34 - 12-32T).

    7 speed hubs are different from 8 & up hubs. You might be lucky and find there is a spacer behind your cassette and can just remove it.
    Otherwise you just need a new cassette and 8 speed shifter.

    A Sheldon Brown article here on it:

    Might also want to check if it is a cassette or a freewheel.

    Yes, with a 8-10 speed Shimano compatible road rear hub. It will have the correct 130mm spacing and also have a freehub body width to fit a 8-10 speed cassette.

    You could also just a take a gear off (on the smaller individual cogs) the cassette and lock out the last gear (#1) on your shifters. Still 7 speed but using 8 speed components. You can do the same with 9 speed components too and have an 8 speed setup.

    A Klein Attitude is 135mm.

    Its probably running a XT 730 hub or a freewheel hub. Photos or a more complete description would be helpful.

    If it is an older XT hub a freehub swap and wheel dish would fix it up.
