    RivBike riser stem question

    I have an '84 MTB with a Nitto Chrome Moly Integral Bull Moose stem,The OD is measuring 22mm.
    The bike is a Peugeot, French but it was made in Japan.
    Will this riser stem work?

    Thanks

    It depends on how accurate your measurements are. A standard 1" (nominal) stem measures 7/8" or 22.2mm on the OD. (matches a 1" fork with a 1/16" wall). French steerers have an ID of 22mm, so they take a smaller stem.

    If you measured accurately, then you need to find a 22mm stem. These are kind of rare these days, but there some NOS ones out there.

    NB the Non French fork standard ID is in fact 22.20mm ie 7/8"

    The stem and handlebars are integral, all 1 piece.
    I have seen these old Nitto Bull Moose Handlebars on '80's Stump Jumpers, Bridge Stones etc.
    I believe it is from the early Ritchey design.

    I have another '80's MTB a Peugeot Crazy Horse that was made in France and the OD is about .2mm smaller.

    As I said, it depends on how accurate your first measurement was. If you now say that it's 0.2mm larger than the French 22.0mm stem, that would make it 22.2mm, or standard 1" (nominal) and ypu can buy the stem of your choice without worries.
