    Setting up newly acquired 2007/8 Bridgestone Moulton
    9 speed obtained from UK.

    As rider at maximum recommended weight (215 lbs) find
    that the front suspension tends to “dive” on braking.

    Seeking suggestions on how to get more resistance in the
    suspension. It’s my understanding that the models produced
    for the UK market had a ‘modified’ suspension which use
    both a spring and polymers as compared to the polymers
    alone on the Japanese market models, presumably due to
    increased average weight of UK riders.

    • Is there in fact both a spring and polymer in the UK models?
    • Can the spring and/or the polymers be upgraded to produce more resistance? I also ride an 1983 AM which I have set up at
    fairly ‘stiff’ setting to avoid the same problem, but the
    adjustments of the leading links, coil spring tension and
    bump stop limiting the travel are all absent on the Bridgestone.

    Any suggestions and a diagram or exploded view of the suspension
    system of the UK BM model would be most welcome.

    The Moulton Bicycle Company should be able to help you. I believe the UK versions were assembled there.

    Here is the Japanese Bridgestone webpage for accessories, including hard springs:

    And a google translation:

    You’ll need a contact in Japan! I have bought tyres and luggage items through family members there.
