    Pffft. Anyone can ride a Brompton at 40mph on the flat - just pedal really quickly.
    Having the power to do so might be another problem entirely.
    Being daft for a second, getting a 61T chainring from Spa gets you a 120" top gear.
    Spin that up to a cadence of 150rpm and you're looking at 60mph.
    Possibly that would be useful descending Ventoux.

    Sod that, 20mph on my M3L is terrifying enough

    Speaking as someone who has overtaken him in a Brompton race, i would say David Millar needs all the help he can get.

    srw It's a bit more complicated than that...

    You didn't need to do that for yourself - there were people waiting to do it for you.

    If you want to go fast on a folder - get a Dahon :-)

    But if you want a folder which goes fast and is also reliable and fun - Brompton!

    each to his own, but I tried the Brompton before opting for a Dahon. The fold wasn't as important to me, the stability and speed of the 20" wheels was better imo

    I can testify that 42 mph on a Brompton is a bit exciting.

    My local bike shop has one of these in the window.

    I eat my dinner off something smaller than the chainring, so I don't doubt it has the gearing for speed.

    Mention on the website of titanium, although it's not clear how many titanium bits there are.

    Given the model name is linked to Millar's clothing range, it all looks like marketing puff to me.

    Is the main frame ever titanium on a Brompton?

    Something rings a bell that it's not.

    Not on a genuine one. There are occasional rumours of one-off bikes that look like a Brompton made out of titanium and/or carbon fibre but Brompton themselves only make steel main frames.

    So presumably the two-speed Millar Brompton is as light as you will ever get a factory bike.

    Except for a titanium bits single speed.
