    120mm hub, 135mm frame

    Can a respaced 120mm track hub be used in a 135mm mtb frame? More of a theory question.

    If you get a long enough axel and enough spacers.

    True, but what about the chainline with the difference widths of the hub bodies?

    My SS roadbike has a 120mm hub and 41mm chainline. Even the granny ring on MTB cranksets is at least 42.5mm, so the chainline will be off. I guess you could work the spacers so the wheel is offset in the drops, or maybe use chainring spacers. But with the latter you might run into clearance issues with the bottom bracket.

    You would need to re-dish the wheel a bit if you go this route.

    Yup. It would be a lot easier just to get another wheel.
