  1. Today at lunch I was telling a friend about how I used to regularly hit
    60mph on a long downhill stretch of road. He said, "not possible unless
    it's a super bike and you are Lance Armstrong".

    I rode a Sears brand 10 speed, nothing special. I was 16-17 years old at
    the the time and rode 10-20 miles a day on a pretty regular basis so I was
    in great shape. I had a cheapo speedometer that had a wheel that meshed
    with the spokes. I never calibrated the speedometer and never had a car
    pace me so I have no idea how accurate the speedometer was.

    The bike was stable at top speed and I never crashed on that run. I'd
    pedal as hard as I could in top gear and then coast during the end of the
    run. The road took a pretty sharp right hand turn and I had to slow a bit
    at the bottom to make the turn. Is it possible that I really did hit 60mph
    on that crummy bike on that long steep hill?

    This is not so much to prove him wrong, it's a silly argument and not
    worth winning. I'm just wondering if it's really possible that I was going
    that fast. Looking back I did not see it as that extraordinary. Has anyone
    else done it and can prove it?

    Highly unlikely that you did it.
    Highly unlikely that a crummy old bike would be stable at that speed.
    Unlikely even that one of those old speedometers with the little gear
    wheels would go up to 60.
    Likely that your memory is playing tricks on you.

    The Tour de France riders do/did, indeed, hit downhill speeds in
    excess of 60mph. Allegedly, one topped out at over 74mph (true?).

    Did you? Maybe. Dunno. Kinda' doubt it, though....

    As others have said, doubt it. I remember the old style speedometer
    with the wheel into the spokes and the cable to the readout. IIRC the
    top speed on mine was 45MPH or so. In modern times I have done in
    the upper 50's (MPH), never broke 60, but I can tell you that when you
    get going that fast you will know it. Better have a stable bike. And
    even getting near 60 takes a good run, some pedaling in a big gear, no
    headwind to speak of, etc.

  5. Yes. I did on a Schwinn touring bike (see my reply to "top speed" on
    this board).

    A couple of years ago I followed my son in my car as he rode his bike
    down a road that begins in Cedar Breaks National Monument at 10,450' and
    ends at 6,000 25 miles later. He was riding a nothing-special Schwinn
    MTB, so he was sitting upright. The fastest he could get, even on
    long, steep downgrades, was 35 mph. The next day I went riding with him,
    also on an MTB. Being considerably heavier, I was able to outdo him by
    about 10 mph on long downhills, so I guesstimate I was doing 45 mph.
    Again, that's sitting upright.
    But as speed increases in a straight line, air resistance goes up
    parabolically. IOW, air resistance is directly proportional to the square
    of velocity. (If my memory of HS physics serves me, anyway.) So even if
    you were on a primo bike, down on the drops, 60 may be a bit much. I seem
    to remember a story about Eddie Merckx tooling down the Alps at over 70
    mph, and reaching into his pocket for a wrench which he then used to
    adjust his seat. Psyching out the competition, no doubt. But you
    probably aren't in Eddie's league.
    If I were a betting man I'd probably bet you made 50 mph, but 60 sounds
    like stretching it a bit. Them cheap speedometers may even have been
    "built to flatter" by exaggerating your speed.

    I dimly remember the story, the version I heard had him on a gravel road,
    adjusting his rear derailleur w/ a screw driver. I would believe the story
    if it was 70 kilometers an hour (43.5 mph), but not miles.

    IME, 50 mph takes a smooth steep road, a good aerodynamic position, and
    usually a fair bit of pedaling in a pretty high (53x13 or 53x12) gear. The
    rolling resistance of the hub bearings and tires on a cheap 10 speed make 50
    mph pretty unlikely unless it was a really steep hill with really smooth
    pavement.

    I think so. I can easily hit 55 on a 15 year old MTB (with MTB tires at
    35psi) on a steep hill near my house. If it was straight I could easily
    go faster, as I actually brake to keep the speed down.

    I imagine that if we put your speedometer on my road bike I'd hit 100.

    I have done 80km/hr down a hill and could have gone faster but I did
    not know the road and chickened out. I was riding a light touring bike.
    The tandem I was with passed me and latter reported 100km/hr. I don't
    see any problem with you hitting 60mph.

    A second-hand story from a friend in NY state was that a high school
    student was ticketed for going 60 in a 50mph zone. Knowing the road I
    can believe it.

    That sounds plausible enough. I'm using a 20 year old Centurion touring
    bike, and have a very basic Cateye Velo 5 computer on it. My town is in
    a valley, so I have a 2 mile climb to get out, and I usually roll back
    down it. The last drop is the longest, probably about 1 mile, and the
    highest speed I've recorded was about 36mph...of course, I've got to
    stop
    for a stop sign at the very bottom of the hill, so I can't just let it
    roll
    out max, but the speed usually stabilizes before the bottom. I could be
    in a somewhat more aerodynamic position, and I suppose I could add a
    little
    by peddling in my highest gear.

    First of all, being Canadian, I would check to see if the speedo reads in
    Kms or MPH. 60Mph is highly unlikely. 60Kph is quite do-able on a long
    downhill. My hybrid is "nothin' special" and I regularily crack 70Kph on
    the Alex Fraser Bridge....kinda scary, actually, now that I think of it :-{

    How did you determine you were going 60mph? When I first raced, we
    had a guy in a Corvette follow the race who assured us we descended at
    60mph, something that with the advent of accurate bicycle speedometers
    turned out to be grossly false. That hill was worth 45mph at best.
    Reaching 60mph on rare occasions (never passing up an opportunity when
    it occurred) assured me that without a tailwind, or taking a flyer off
    a 50- or more mph camper truck required at least a 13% grade... one
    that is straight and smooth.

    Typically, Sonora pass with its 20+% grades barely gets one up to
    50mph because there are no straight steep sections. In general there
    are so few straight steep roads that speeds over 50mph occur rarely.
    My first such experience was on the Pso Rombo/Timmelsjoch pass from
    Italy into Austria (?tztal). This is a classic Austrian steepy and it
    has a convenient uphill runout after the chute just after he summit.

    Tioga pass is not a fast descent, it having little more than an 8%
    grade, but on the right day, with the right wind, and camper trucks it
    can yield over 60mph. In all the years I have descended to Lee
    Vining, such conditions occurred twice for me.

    Bob Roll, professional racer, said he topped 60 two or three times in
    his racing career.

    I don't believe a word of it. TdF racers are definitely not heavier
    than I and my downhill friends are and we have never gotten over 50mph
    on the roads to which Phil Ligget has attributed such high speeds.
    Professional racers will tell you that there is no benefit in
    getting to the bottom of a descent first (and alone) although there is
    a large loss of safety trying to do so in a race.

    Knowing how hard reaching 60mph is, 74mph is absurd. You'll need to
    qualify that to bring it any credibility. On what road under what
    circumstances. A sports announcer's word doesn't cut it.

    Those guys go 90mph. A taller bike and lack of fairing is certainly
    going to slow you down somewhat, but I'd bet any off-the-shelf bike can
    hit 60mph on a big hill.

    And in Colorado, big hills are plentiful.

    Well, yes, but suitable roads for 50+ mph descents
    are not that plentiful. There are some out there though.
    The big Five Oh can be had on Sugarloaf, in Boulder
    Canyon, Golden Gate Canyon, the top of Left Hand near
    Ward, Sunshine Canyon, the back side of Rist Canyon,
    that I know of. It really is not advisable to go for
    50 on any of those sections, especially Boulder Canyon.
    One of my very few forays into the 60 mph range came
    on the back of Rist, an incredibly straight descent
    westbound to Stove Prairie. This was some years ago and
    the road was a smooth gravel surface, four of us on
    mountain bikes loosely drafting hit 60-61 mph.

    It's not how "big" but how steep. If you consider that bicyclists
    sprint to 40mph and the same rider reaches 85mph in a fully faired
    streamliner on the salt flats you can see that there is little
    comparison between a Schwinn clunk and a fetal position low rider.

    Colorado may have high mountain passes but they are not steep, and the
    steep ones are back roads with curves that prevent high speeds.
    Classically:

    Tennessee Pass (elevation 10,424ft; 6% grade) road.
    Tennessee Pass (elevation 10,424ft; 3% grade) RR

    Is a typical famous road and railroad.
