  1. I went out for my first longish ride on the Single Speed today. It's
    only got a 39/18 combination partly for the hills but mainly because I
    want to force myself to spin more. On the flat and downhill I was really
    pumping but kept finding myself bouncing once I hit my highest cadence
    levels. A couple of times I seemed to find myself in a bit of a zone
    where I was spinning smoothly, but that only lasted 5 secs or so and
    then I was bouncing again.

    Is there anything to keep in mind to avoid this, or is it just a case of
    practice at high cadence?

    Concentrate on the top & bottom of your pedal stroke -
    forget the push and don't lift (at high cadence you won't
    have time to anyway). Imagine you're scraping gum or
    dogshit off your shoes at 6pm, and pushing your toes into your
    shoes at 12. Then, practice, practice, practice ...
    You can also do core work - swissball/yoga/pilates/swimming/
    kayaking etc to strengthen your hip stabilisers.

    Some schools of thought would say that very high cadence,
    while impressive to look at, don't make you a faster
    cyclist, so don't get obsessed by it. It's only
    juniors that have to whirr away at 150rpm.

    What sort of high cadence are you talking about? 130rpm or 180rpm?
    I was cranking at 170rpm (39/16) last week at which point, the chain
    started slapping the bottom of the chain stay. Of course, the only
    racers you'll ever see turning cranks at that speed are track sprinters,
    which I'm not, so I'm not worried about bouncing at that sort of speed.

    phffft! too much thinking involved!

    the secret is DONT think.

    youre 2-1 ratio is the usual and the whole reason its a SS is so you can wimp out (unlike us 'bruteish' people who ride fixed! 😄) going downhill.

    It may simply be a position thing. Check your saddle height aint too high, and i find moving forward on the saddle marginally gives you 'room to spin' more.

    i also find on the wide-barred mtb SS the wider hand position seems to promote hip-movement a bit more too which makes spinning harder too.

    Well I don't have a bike computer on this bike but I'd say around 130
    which is high for me.

    Get a smaller cog or a bigger chainring.......you know you want to!!!!

    Someone at work told me that I needed to "be kind to your knees" when a
    group of us were talking about SS bikes. Screw that!!! I have been away
    with work too much lately and I am getting [censored] at being off of the bike
    (not to mention getting fatter). I have decided now that for the next month
    or two I am going to smash myself on the bike to and from work, as well as
    concentrating on leg work in the gym. I am upping the ratio on the SS from
    38/16 to 38/14 and will ride that to work at least twice a week and I am
    going to go the long way on the other two bikes for the remaining days (30km
    for mtb, and Burgandy St, Yarra Blvd for the roadie). I am also keen to get
    in a couple of BRs and races. Time to get motivated!!!

    Ride On,

    No, No, No! All BR riders must lose form, put on weight and generally be in such a state so that when my inevitable return comes I can keep up 😄
    Oh, bugger that. go on then.

    No way Dutch, I'm on fire and next BR you are on you'll be eating my dust.

    actually, youre recent times have me genuinely worried 🙁

    on my return from Amsterdam/paris/NewYork I think my climb-trial time was... (cant clearly remember) but i think 16:45?

    so if youre already doing sub 16's and with a few more months in difference i expect you to be approaching 15min and me scraping to beat 20min!

    MUST get on windtrainer!
