Cycling Conduct: Bicycle Specifications Part II

By USA Triathlon | Jan. 13, 2014, 5:35 p.m. (ET)

This week’s rule continues the series we started last week on bicycle specification rules.  

5.11f forbids aerodynamic attachments worn under or over a cyclist's clothing that would have the effect of reducing wind resistance while on the bicycle. However, an exception is made to allow the use of approved aerodynamic bicycle helmets.

Over the past two decades we have rarely seen any violation of this rule but once encountered a product which appeared to be wing or fin-like attachments on a cyclist’s arms. Needless to say, those attachments were illegal.

Here’s the rule:

No additional equipment, whether it is worn under the competitor's clothing, over the competitors clothing, or is otherwise attached to the athlete's body, which has the effect of reducing wind resistance is permitted. An exception is the use of safety helmets as described in Section 5.9. Such helmets may have the effect of reducing the wind resistance of the head only.
