    Handlebar type matters

    Which cable you need will depend upon the handlebar type and the shifter type

    • M type - the classic Brompton style - also known as Mid rise
    • S type - straight / sports style - also known as Low rise
    • H type - a slightly higher riding position - also known as High rise
    • P type - multi positional riding position - now discontinued and not to be confused with the P Line

    If you are unsure - we made a guide on how to identify your Brompton handlebar type
