  • I'm sure that there was a thread which dealt with these kind of questions but I can't remember/find it so asking here. Sorry for the long post!

    I'm looking at a 1991 Dawes mtb in Reynolds 500 and wanted to know if there is going to be any funny sizing to thwart a build. I've got a 9 speed Deore gear set I want to use.

    1. canti spacing: can I use modern canti / v brakes or will they be narrow only allowing a limited choice of cantis?
    2. seatpost size?
    3. 1" or 1⅛"?
    4. is 1⅛" threaded cross compatible with 1⅛" threadless/ahead? ie can I just get a 1⅛" threadless fork and a new headset?
    5. wheel spacing? Anything funny?
    6. Any other funny business? 26" wheels that aren't 26" and won't take easily available tyres, etc?

    Cheers

  • canti spacing: can I use modern canti / v brakes or will they be narrow only allowing a limited choice of cantis?

    Should be fine. I have TRP Eurox cantis on a 1992-ish fork. I expect the brake pads are mounted a few mm further on their studs because I have fairly skinny wheels by today's standards but it all fits and works fine. I've also had DX V brakes on that fork.

    seatpost size?

    Don't know, sorry.

    1" or 1⅛"?

    Could be either of those, or maybe 1-1/4". 1-1/4" is fine but bear a few things in mind:
    -you have very limited choice of stems and headsets
    -you won't be able to go threadless like you're planning to without some careful headset planning
    -if you just want to use an a-head style stem you'll only be able to use the Nitto mt Column which is $$$ and impossible to find anywhere

    is 1⅛" threaded cross compatible with 1⅛" threadless/ahead? ie can I just get a 1⅛" threadless fork and a new headset?

    Pretty sure it is, yes.

    wheel spacing? Anything funny?

    The frame might be 130mm OLN spacing at the back. Newer stuff will be 135mm+ but 9-speed will be fine with any of those.

    Any other funny business? 26" wheels that aren't 26" and won't take easily available tyres, etc?

    No, 26" 559 on mtb is 26" 559 on mtb and there are loads of widths to choose from.

  • Cheers that's super helpful.

    My Dawes CX from the 90s has really narrow canti bosses / studs on the fork and its such a fucker.

    @Pifko thanks, that's useful.
