Wo wenn nicht beim Zeitfahren darf man die Dinger denn fahren?

Würde sagen, beim Triathlon.

Zu Roadraces schreibt die UCI folgendes:

For massed start road races and cyclo-cross races only wheel designs granted prior approval by the
UCI may be used. Wheels will have minimum 12 spokes; spokes can be round, flattened or oval, as
far as no dimension of their sections exceeds 10 mm. In order to be granted approval wheels must
have passed a rupture test as prescribed by the UCI in a laboratory approved by the UCI. The test
results must show that the rupture characteristics obtained are compatible with those resulting from an
impact sustained during normal use of the wheel. The following criteria must be fulfilled:
· On impact, no element of the wheel may become detached and be expelled outwards.
· The rupture must not present any shattered or broken off elements, or any sharp or serrated
surfaces that could harm the user, other riders and/or spectators.
· The rupture characteristics must not cause the hub to become separated from the rim in such a
way that the wheel becomes detached from the forks.
Without prejudice to the tests imposed by the laws, regulations or customs, standard (traditional)
wheels are exempted from the rupture test referred to above. A traditional wheel is deemed to be a
wheel with at least 16 metal spokes; the spokes may be round, flat or oval, provided that no dimension
of their cross sections exceeds 2.4 mm; the section of the rim must not exceed 2.5 cm on each side.
Notwithstanding this article, the choice and use of wheels remains subject to articles 1.3.001 to
1.3.003.
