Brompton tyres sucking the life out of me

    The saddle seems to be in the right position, it's certainly not uncomfortable.
    I do also have the seat post at the max. I'm 5'9", so anyone taller must have a bit of a problem or have a taller post.

    It's more about aero dynamics. Brompton set up their bikes with the sadlle pushed as far forward on the rails as it will go - obviously making you more 'sit-up-and-beg' It was one of the first things I altered. Flipped the pentaclip the other way up and pushed the seat right back.

    I also think they do take a lot of getting used to.

    After 30+ years of riding MTBs I bought my first road bike (or racer as we used to call them) about 3 years ago and it felt really twitchy. Now when I use the road bike after being on the Brompton all week, it feels really planted.

    It also takes a while to get used to the gearing.

    At 6 2 I should probably have got the extended post but get by with the pentaclip reversed and as close to the top of the post as I dared.

    I don’t commute on it now but when I did I found the Brompton green tyres ok. I dislike the M+ that I tried on a previous bike and have never purchased any since. Did run Marathons on the tourer and they weren’t too bad.

    Thanks @Kell That's very interesting about the saddle. I may have a look at that.

    I wish my bike looked as clean as that now too. :blush:

    Here’s mine with the extension. The carradice block obscures it a bit but if you zoom in it’s clear.
    It’s a standard part.


    Gives a tad more height as well :-)

    Marathon tyres are slow!

    Schwalbe Kojaks are so so much faster and give the bike a completely different feel, just stick some stans no tubes sealant in the inner tube and you wont get punctures!

    I left a stripe of latex along King Street a few years ago that would disagree with that! I suspect it depends what you're puncturing on.
