  1. If recumbents were allowed in the Tour as well as any other
    professional race event, do you think any riders would switch or at
    least experiment with recumbents? My guess is they might switch for a
    fairly flat time trial but that's it. I have watched and marveled at
    the pros as they dance on the pedals while climbing switchbacks so
    steep I'd be looking for a ladder! Under these conditions, I argue
    the recumbent cannot compete. Any thoughts?

    Cycling's definitely going to evolve. In what ways... I don't know.

    But, I definitely don't see it going towards recumbents. And, I don't
    think we'll ever see a day when recumbents are allowed on the Tour.

    That said, I wonder if there are races involving only recumbents. Has
    anybody seen one?

    There are lots of recumbent races. The USA has HPRA and there are also IHPVA
    races in the US and Europe. Since the races are 'human power' any kind of
    bike can be raced. There is a racer from Michigan who races a Cervalo with a
    small front fairing and lycra body sock. He's pretty fast, but the general
    race crowd rides low racers.

    You could take a look through www.recumbents.com for information and photos
    of the human powered racers at several different venues over a period of
    years.

    On a stage which is a pure climb then weight of the bike will have a
    more significant beariung and aerodynamics will have less, as the speeds
    are lower. So on a pure climb you'd probably lose out.

    But on mixed (not just flat) sections it's not so simple as that...

    In the 2003 Classique Genevoise there was a recumbent class, and the
    recumbents took the day (see
    http://www.m5-ligfietsen.nl/site/EN/Races_and_records/Classique_Genevoise/).
    Now, M5's site only talks about the 2003 event, I don't know what
    happened since then!

    The UK "End to End" record has been held on a faired recumbent trike for
    quite a few years now, and that's a *big* route (over 800 miles) with
    lots of significant climbs, yet still the recumbent holds it.

    PBP has yet to have a 'bent as the fastest, I think, but the fastest
    'bent finshers are up with good times and of course they have far few
    fewer riders who regularly race.

    So I think more than flat time trials would see 'bents. And on the
    track they'd be dynamite!

    This is a thought experiment, as the TdF would never allow it.

    My guess is that it would be difficult to convince racers who
    commit years of training to UCI-specified bike racing to
    embrace a different design. They simply wouldn't consider
    it "bicycle racing". That's perfectly understandable.

    Spin, spin, spin, to win has been the answer for mountainous
    stages in recent TdF, hasn't it?

    Oh, the "recumbents can't climb" discussion! %^)

    Okay, imagine two bikes and riders of the same weight and
    with the riders having the same power output capability.
    One bike has a measurable aerodynamic advantage. All
    other factors being equal, the more aerodynamic bike will
    be faster, even up hill. The faster the riders, the more
    difference the aerodynamics will make.

    So for the less aerodynamic bike rider to win, there
    needs to be some ergonomic or mechanical advantage
    to the available riding positions or techniques. Such an
    advantage is often asserted for upright bike riding position
    and particularly for climbing. Some possibile advantages
    offered include:

    - ability to recruit more or different muscles increases
    power output
    - using shifts in body weight offers some mechanical
    advantage
    - standing allows resting of some muscles

    As far as I know, none of these assertions have
    tested or advanteges quantified in a controlled study.

    Logic seems to indicate that if any of these or other
    better upright climbing methods are true, they must
    come at some expense (higher drag, limited endurance,
    etc) or the techniques would be used in a sustained
    fashion.

    Do you meain bicycle racing or cycling in general?

    If you mean cycling in general, how about the crank-forward
    designs,-- that's going "toward" recumbent, isn't it? %^)

    No, too much history there.

    In any case, like with sailing races, there's an element of
    one-design-class contest for many bicycle races.
    http://en.wikipedia.org/wiki/One-design

    TdF is not supposed to be about the bike, don't you know?
    It's about the *pharmaceuticals*! %^)

    There are a number of open-class races and records
    where recumbent designs, both faired and unfaired
    dominate, see IHPVA:

    http://en.wikipedia.org/wiki/International_Human_Powered_Vehicle_Association
    http://en.wikipedia.org/wiki/Sam_Whittingham

    There are various cycling records which show comparitive
    performance across bicycle categories.

    http://en.wikipedia.org/wiki/Hour_record

    It's pretty clear from a "pure speed" perspective that
    aerodynamics are the limiting factor. Note the distinction
    within records for upright bikes with "unorthodox positions".
    Note the curve of the one-hour records plotted for
    UCI vs. IHPVA.

    In personal anecdotal "real-world" comparisons, I, a
    non-racer, overweitght recumbent rider have been able
    to keep up with younger, fitter upright riders on multi-day
    self supported tours around Taos, NM, and in hilly
    southern Oklahoma,-- climbing faster in some cases.

    Some sugar daddy would have to pony up a couple hundred million to build
    teams to do any major kind of race, and to have enough teams to make it a
    race. The pros will ride what they're paid to ride as long as their union
    and league rules allow them to. I think it probable that rider contracts may
    stipulate branding requirements for equipment. There's a photo bouncing
    around the net of Jan Ullrich riding a Baron or Jester. His pro days are
    probably over, but I haven't seen his name mentioned as participating in
    Euro championships, or him having been hired to be the motor for a world
    record run in a Battle Mountain speedbike.

    So basically the whole argument is moot. The TdF is about artificially
    preserving the classic equipment used in the race and reaping gazillions of
    Euros in sponsor and ad revenues.

    I talked to some state champion track racers at the Northbrook track who
    were watching a couple of NoComs doing hot laps on the track. They were
    interested in them, but they weren't going to make a career change to beat
    up on the few geezers who race the HPRA circuit. These are atheletes who
    compete at a pretty high level and at that level and discipline the
    competition is is riding fixy track bikes.
