Time Trial / Time Trialling / TT

In general, we have found the following to be a good guide, and these are the rules that many of the events below will follow:

1. No aerobars, clip on aerobars or aero extensions can be used
   
2. Hands must be holding the handlebars at all times whilst racing (ie. not with forearms resting on the handlebar)
   
3. Wheels must have a minimum of 12 spokes each, and have a maximum rim depth of 90mm
   
4. Helmets must have no visor
   
5. Ears must not be covered by the helmet (Giro Aerohead helmets are not permitted)
   

These are Xav’s rules for the road bike. Is there anything specific that people would add or remove from this to improve them? We are meeting tomorrow to decide on the rules for a road bike category in all of our upcoming TTs and these are already a substantial improvement on what has so far been suggested.
