I did a long ride on Sunday over Durham and north Yorkshire! On a steep decent I maxed out at 62.8 mph! Was just wondering what speed you guys have hit as a few of my friends don't believe me haha

  • Were you pedaling? I never understand how people get above 60+..

    It's a topic that keeps appearing often. For some reason.
  • No I wasn't! Iam 97kg tho so this will help?
  • moors?

  • 62.1mph in mallorca (didnt know until i looked back at garmin record)
  • Yeah was down the moors! First ride down there as I love in Northumberland! I will def be going back

    ~75kph in the Dolomites on the descent into Corvara from the Falzarego (IIRC) and I was braking as I'd gone beyond the point of feeling in control. However it didn't deter some as I got passed by more than a handful who I reckon were doing close to 90kph.

    I seem to remember reading somewhere that Magnus Nacksted saying he's managed around 128

    Feel much safer on a set of planks and managed 108kph in the same area in the winter.
  • On my PX, 74.32mph uphill, towing a truck.... :twisted:

    I love this topic :D
    Science adjusts it’s beliefs based on what’s observed.

    It's not the same without a youtube video and a photo of a clearly faulty cheap cycling computer though.
  • Only impressive if it's uphill, anyone can be fast on a straight line descent.
  • I am not that suicidal, about 50 to 55 mph...

    I am not even that suicidal, about 45 mph...

  • What I'd like to know is:

    At what speed are you when your legs just can't pedal any faster and any increase in speed after that is purely down to degree of incline?

    Assuming a top cadence of 160:
    - on my bike, which has a top gear of 50-13 its 48mph
    - on a 53-11 geared bike its 60 mph

    About 80 kph although on most of the roads around here about 72-75kph max.

    If you got good leg speed and your completely spinning out in 53x11 then lets just say your going very fast. Fast like if you come off your ass is history.

    Very dangerous and tbh you'd be better off just bombing down hills around 30mph then just add on another 20-30 mph when your on the internet.

    Excuse my ignorance, are we talking the cassette here?

    Sorry but I'm still learning!

    No - it's straightforward mechanics. If you pedal at 160 cadence, a 53-11 gives you 60 mph assuming drlodge is good at his maths.

    Whether you can actually do that is another matter. Even with a pretty steep descent, air resistance becomes such a factor that pushing 160 cadence in top is probably not going to happen. The best I've managed is 50mph and that is off pretty steep Pennine hills. It takes a long time to reach those speeds and I'd rather not be thrashing around at 160 cadence when doing it.

    But a longer, straighter steep descent than I've found so far could probably get me at least 55 but maybe I'm too light to make 60mph in England at least.
    Faster than a tent.......

    I'm laughing now as I googled 'Cadence' to get a better understanding of your reply and came across this article:

    Phew!
  • Got 39mph on my Triban 3 on a slight descent. Hadn't my glasses on though so the midges were hitting me like hail stones so I didn't dare push any harder. I've noticed that everything waters at speed, eyes and mouth especially. I even had water dripping on me from my helmet somewhere.
  • Certainly does! A face full of snot is a sign of a fast decent
  • 48 is about my max and thats spinning out on 53x11 downhill

    48.6 MPH on a ride in Northumberland a few years ago and I have no wish to go any faster. I was out with a group who were fitter and faster than me and I had been hanging on for grim death for the whole ride. There was a steep descent towards Haltwhistle and they were off. I had to hang on or get dropped. It was twisty and narrow with farm entrances and hedges, and If I had used my imagination and thought of what could have been the outcome If a tractor had pulled out or been parked on a corner!!!!!!
    On another ride I, luckily, did not attend, one of them touched a wheel on a decent and all four of them finished up in an ambulance. Downhill hero? not me.

    I used to go about 50-60MPH (don't know exactly, but that's what I judged it to be), but after a sudden thought of what would happen if I suddenly had a puncture or hit a deer or something I changed my mind. I'm going to take descents easy from now on. I actually love climbing now!

    I have no idea what's going on here.
  • At the risk of being flamed because of being new to the forum...but... are people seriously claiming to have ridden an actual 60+mph on their road bike??? Or are you just all taking the piss out of the OP?
    I'm not saying I don't believe you (which, by the way I don't) but seriously... why not just send your broken Aldi bike-computer back for a refund? Or take the second magnet off your spokes so that one rotation only counts once. Or calibrate your wheel circumference to something bigger than a chopper front wheel. Or just learn the difference between the KPH and MPH readout?

    60mph down hill is not impossible. I've hit the mid 50's a couple of times, but chickened out as I approached 60. But I have been passed by those who have hit 60mph. Whether the OP managed to go over 60 I don't know, but it is possible.
  • 60mph...It is possible - not by me though...my balls would be far too small for this:

    Could you please explain your 'judging' method?
