    Does a Brompton flex or creak under hard riding?

    Wondering if a Brompton creaks or makes noises under hard riding like climbing hills or sprinting.

    handlebar-stem "joint" only. I used to ride a couple of S-Type Bromptons quite aggressively. The only place producing flexy noises was the Al. handlebar (replaced on almost all my Bromptons)

    The bolt that goes thru the rubber suspension piece needs a little grease on it.

    hammer heads have the firm suspension elastomer as an option now.

    seems putting a hose clamp around the rubber piece was been used, too.
    limits rubber expansion as the suspension compresses it in length.

    I seem to get some creak when pedaling hard out of the saddle, but not more than I would on a full size bike. The frame is a lot stiffer than I thought it would be.

    As a new Brompton owner accustomed to 20" Dahons I'm finding the stem quite flexy. No creaks so far, but the ride is noodley.

    I had my own Brompton for over 5 years now. No sound beyond the soft clicks or ticks of the internal hub in motion.

    I find if I get creaking it's time to get the cranks off and re-grease the splines.

    Crank those T handles on the hinge joints tight enough ,
    and it should be sufficiently solid.
    any issues and that's the 1st place I check.

    I have the 2-speed Titanium S-Type with the firm rubber block. Absolutely silent while riding... about the only noticeable sound is the free-wheel ratchet while pushing the bike alongside me around the railway station (and I quite like that sound)

    The Dahon MU SL's I had squeaked and creaked like a pig.... really embarrassing riding past people (espcialy kids) who would stare and shout comments
