When it comes to time trial helmets, POC has made a bit of a name for itself over the past decade. Its Tempor helmet was years ahead of its time when it launched at London 2012 Olympics. It put a revolutionary spin on design and it's enormously popular in the time trial scene for the radical shape that is designed to push airflow past the head and beyond the shoulders. It's said to be extremely aerodynamic in the wind tunnel and when in the ideal TT position. However, as soon as your head moves out of its perfect tucked position, its above-average size can quickly result in a net loss in watts saved. 

Enter the POC Cerebel, the brand's 'normal' time trial helmet. It adheres to the bobtail design blueprint which is said to help it remain aero no matter what position your head settles into. So while the title chasers and elite racers might find the Tempor to be the faster of the two, the POC Cerebel is likely the best time trial helmet in POC's range for the vast majority of time trial enthusiasts.
