    Brompton rim ERD?

    Hi,
    I've seen varying stats for this, does anyone have their own measurements? I'm not able to measure it myself.

    Velocity in Australia , and Sun USA also supply a 349 rim ..
    My rim is sourced from Alesa, in Belgium, original parts.
    varying sources would give a variety of ERD numbers.

    Bike Friday and Brompton may answer your question , via websites
    or perhaps SJS, a source of spares in UK.

    That's what I would do , in your situation..

    I got info from SJS, but sparing shipping 1/3 of the way around the globe,
    went thru LBS, and special ordered 30 short 13 ga 150mm spokes to be cut,
    [they don't have a bulk spoke cutter, locally]
    to replace/rebuild my UK steel shell AW3 after an original spoke broke..
    as I expect there may be a cascade of fatigued spoke breakages pending..

    I'm building a new wheel with an X-RF5 hub. SJS gave me a measurement but I wanted to double-check it as it's quite different from what I've seen on forums and on spoke length calculators.
