Our technical regulation about time trial competions is applicable since 7
years. Our message of this year is only a focusing. There is not a new rule.
According to our article 1.3.023 about time trial competitions, an extension
may be added to the classical steering system.
The meaning of the rule is that the forearm must be horizontal (see shema -
structure 1b -). In fact, that goes without saying by reason that we have
only 3 points of support authorized (foot, seat and hands). If the forearm
is not horizontal we have an other point of support.
The shape of the bar extension is generally horizontal with an ending hand
extension (handle). From aerodynamic point of view the full horizontal bar
extension is the best but it is a constraint from physiology point of view.
It is the reason why the ending bar extension (handle) is free.
In other words, the shape of the bar extension is correct if the forearm is
horizontal (except the handle). Now, of course, we find different bar
extension which are not always strictly horizontal. It is not a major
problem if, in fine, the forearm is horizontal.
However, the translation of our technical regulation from the French text is
not very good. The English text 1.3.023 - A support for the elbows or
forearms is permitted - is wrong. The French text is : Un repose-coudes ou
avant-bras est autorisé. It is very different. The correction has been
requested in march and will be actual on the next version of our technical
