  1. If you saw the TdF TTT, you might have noticed the bars on a few of the
    Gerolsteiner's bikes: tiny cowhorns without aero handles in the middle.
    They rode them (to victory) at Eindhoven TTT, too.
    These bars really didn't look that aero with big riders like Michael
    Rich on them. The riders didn't look that stretched out. Wonder if
    anyone is familiar with these bars and has any thoughts on their use,
    their aero qualities.
    I've seen similar on the track for the kilo, but not on the road.
    Lately anyway.

    J
    ps This post's subject (unusual new equipment that isn't seen across
    all ProTour teams) made me think about the crazy days of the early to
    mid 80's when the most outrageous stuff made appearances. Anyone
    remember the front wheel on (I think) Visentini's TT bike where the 24"
    front disc was actually closer to a "ball." Thinking was, it would
    create an air pocket for the churning pedals; Moser's huge, weighted
    rear wheel on one of his hour bikes; etc etc...Interesting, too, that
    the Czeck who recently set a new hour record rode a weighted 3.2kg rear
    wheel. How can that be allowed for the "pure" record?

    Here's a photo:

    I can't find the link now, but I seem to recall reading that the team
    determined by power measurements that the strange handlebars were
    faster. The interview implied it had to do with the drafting team,
    rather than each individual being faster. Also there was some feedling
    that having fingertip controls (brake and shift) may have lead to
    faster team times. I guess that's somewhat reasonable when you see some
    TTT riders with hands on their starting handles, not in the aero bars.

    Here are a few links to explanations:

    A related comment during stage 4's TTT in the 2005
    TdF(http://www.cyclingnews.com/road/2005/tour05/?id=live/tour054,
    scroll down to 16:16 CEST) says:

    "16:16 CEST
    ....Gerolsteiner is riding with special handlebars today, as DS
    Christian Henn told us, "We tested the handlebars during training, when
    we reconnoitred the Tour de France TTT parcours. Two years ago, some of
    our riders had them already at the Tour. They're wider in the aero
    position, which makes steering easier. Clip-ons on the usual TT bars
    are very narrow. The disadvantage of this special set-up is that when
    there are many turns, it's harder to regain speed after the curve,
    because you lack the width of the usual TT handlebar. But when the
    course is pretty straight, the team tends to drive more steadily, and
    another advantage is that the brakes are right within reach - you don't
    have to change position to brake. You can ride wide curves flat out on
    in aero position and ride closer to the wheel in front of you, because
    you feel safer."

    "Michael Rich especially is very much in favour of these bars. We hope
    for a good result at the Tour TTT - let's say top eight.""

    Also, in Levi's diary
    (http://www.cyclingnews.com/riders/2005/diaries/levi/tour05.php?id=levi0511)

    he says:

    "Most of the guys are using special team time trial handlebars. I'm not
    because I've chosen to adjust my normal time trial bars a little wider
    instead. This way I can stay in them the entire time and still handle
    my bike.

    Making them wider makes the entire team more aero even though it
    doesn't really make the individual rider aero on the front."

    I read that these were exclusively for the TTT and not the ITT. The wider hand
    position was thought to have a negligible aerodynamic effect as a team and be
    more comfortable, stable and easier to generate power.

    Or should they be required to drill everything like Merckx's bike?
