  1. From another message board (the RANS/Crank-Forward forum, off of
    http://www.crankforward.com/ ):

    http://pub23.bravenet.com/forum/1970022224/show/590156

    From my upright-riding days, I had read of some types of experimental
    track/race bikes that had seat tubes all the way up to 90-degrees, but I
    never saw anything like that actually on the road. And I don't remember
    anything that put the cranks /behind/ the seat.

    I do know of "prone" bicycles in the history of HPV racing, but those
    were ultra-exotic, totally unsuitable for any sort of regular riding.
    They did not resemble what this is.

    I doubt I'd want one, but I am curious: does anyplace out there
    regularly make a "upright" bike frame anything like this? And I suppose,
    a saddle to go with it, as it certainly isn't using a conventional saddle.

    Looks like do it yourself anesthesia for a sex change surgery.

    The forum says this guy was going along at 30 mph. I have to be
    skeptical that changing the angle would make for such a huge increase in
    power - unless of course this guy usually goes 35 mph.

    There is also the extra pressure on the arms / hands. I wish we had the
    rider to discuss instead of some highly speculative comments on the Web
    site.

    I think bikes like that were all banned by the UCI.
    The UCI wanted more noemal bikes and less technology or something like that.
    Whatever that means.
    So these bikes couldn't be used in regular racing circles.
    Now they have strict rules as to how far forward a saddle can be and how
    short it can be, etc.
    When you see photos of the top TT riders they are all sitting forward on the
    front tip or edge of the saddle now, in order to still have a legal bike to
    ride.
    A bike like that simply moved the saddle forward to make it more confortable
    when you are low down in your aero-position riding along.
    Usually a rider would be resting their upper body weight on their forwarms
    when in the aero-position, and if they are pedaling strongly, there isn't
    much weight on the saddle.

    The UCI is about halfway to obsolescence, as I see it, frogs in the well
    parading to irrelevance. The best / fastest / most-comfortable bikes in
    the world aren't legal under UCI rules.

    At one point in time, there were probably a lot of organized races for
    penny-farthings, too.

    Yes, not allowing recumbents to compete in upright bike races is clearly
    making upright bike racing disappear overnight, and has been doing so for
    the past, what, 3 decades?

    What is a recumbent?

    Despite the technological impressiveness of unrestricted HPVs, can
    you imagine watching them race? It'd be incredibly dull.

    I think that would depend on the race. Certainly the straight line speed
    records would be boring for a spectator, but if the same race courses
    applied for unrestricted designs as for current "legal" ones, it could be
    very interesting. Personally, I don't see why something like the angle of
    Floyd's aero handlebars should be a point of concern - and if someone
    actually wanted to ride a recumbent in a time trial, that would be very
    interesting to watch.

    Yeah, like watching paint dry. Something I just love to do. In fact, I
    always have a can of paint and a paintbrush handy just in case I have
    the urge to watch paint dry.

    Graham Obree's bikes didn't seem to cost that much, and no corporation
    sponsored him.

    As for comfort--recumbents would win there easily.

    As for safety--that is very questionable: to pre-emptively exclude a
    new/alternate bicycle type, because they "think" it might be not-as-safe
    as the bikes that competitors commonly crash on now.

    I'd like to see a mini-cam on every entrant (or, perhaps the top-25
    qualifiers). And then a website where I wan watch streaming video of
    whichever camera I want. I'd bet I'm a lot more likely to see this
    happen with IHPVA racing than UCI, just because IHPVA isn't dependent
    upon corporate broadcasting income.

    Also I'd like to see TT-style racing, with single riders starting at
    staggered times, with teammates scattered through the field--so that
    drafting with teammates wouldn't be possible. How about a race of
    "single riders"? How about making drafting /illegal/?.....

    I'm glad you brought up Obree. I think he was riding a setup that was
    effectively similar. Did the "Superman" position put the bb behind the
    seat? Wasn't that part of the reason why the UCI set the standard
    against it?

    Obree's bikes still had the pedals in front of the seat by a small
    margin, in the photos I'm finding. When he scooted forward on the seat,
    he was riding right-about-over the BB. This other fellow's bike has the
    BB at least 2-3 inches /behind/ the seat.
