Time Trial Helmet Reviews

giro air attack shield helmetWhen it comes to safety in a triathlon number one is to have the best bike helmet available to you.  

The bike is by far the fastest part if the race so you want to make sure you are protected in case you take a tumble.  

You can’t enter a race without a bike helmet and you will be disqualified from the race if you transition from swim to the bike without clipping up your helmet.

Same goes for when you finish the bike section.

You must keep your helmet on and fastened until you stop completely and the bike is racked.

Helmets come in many shapes and sizes and this post will concentrate on full triathlon style helmets.  

They look very different because they are shaped for maximum aero dynamics and it is not an item that you would be wearing whilst out on a leisurely ride in the countryside.  

Well you might but you will get a serious amount of ‘blank stares’ from people as you whizz by.
