Hi guys, I recently bought a second hand wilier la triestina. Need to change the stem but I have know idea of the size of the fork steerer or bar. Any clues? The bar is quit meaty so i'd guess at 31.8, i think this is a fairly size?

cheers for any help

    stem length is measured centre of steerer to centre of clamp

    clamp will be 31.8mm, as you say, and the steerer will be 1 1/8"

    bar width are measured centre to centre

    other issues are stem rise - usually between 6 and 10 degrees

    and whether the bar is comapact, anatomical etc. in terms of shape

    Some bars (mostly Italian ones) are measured outer-outer.
