Helmet Sizing

Measure around your head at the widest point to determine the size you need.

Size guidance: To help choose the correct size helmet for your head measure around the widest part of your head, about an inch above your ears, with a soft tape measure, or piece of string. If you are on the cusp between sizes we advise that you size up.

Road CC have just reviewed the Kronus TT Helmet and gave it a whopping 4.5 stars. Not bad for a helmet that's half the price of the competition.

Aerodynamic Profile

Designed with our sleekest aerodynamic profile yet Carnac's Kronus Time Trial and Track Helmet will facilitate shaving seconds off your times and protect you from those inevitable racing incidents. With a sleek frontal profile, it helps you slice through the wind and it's so adjustable and lightweight that you're sure to be able to find your perfect fit.

A wide field of view is provided by a replaceable Tru-Sight visor made from optically clear polycarbonate and profiled to offer maximum clarity with reduced peripheral distortion. Held in place by high power Neodymium magnets you can quickly swap between different lenses choosing the right lens colour and light transmissivity for the lighting conditions.

Occipital Cradle

As well as keeping you cool with 6 strategically placed, front facing slit vents the Carnac Kronus Helmet provides outrageous comfort. Our Occipital Cradle is fully adjustable for width and height. A 70mm width adjustment range coupled with a 12mm of height adjustment and our anti-bacterial treated soft pads ensure the widest possible range of adjustment.

Built using our proven single-shot construction, a full coverage EPS core is co-moulded over the fittings that anchor the straps and occipital cradle into the body of the helmet for maximum durability. If you're looking to accrue marginal gains to improve your performance a brilliant aero helmet can save you watts and precious seconds on every ride. 

A correctly adjusted chinstrap is an integral part of the safety provided by any cycling helmet. If your chin strap isn’t correctly tensioned there is a risk that the strap may pull through the buckle. Always make sure that the chin strap is adequately cinched up every time you put your helmet on. A loose chin strap potentially reduces the effectiveness of your helmet.

NB: Optically perfect Tru-Sight visors are available in a range of tinted mirror finishes to suit all lighting conditions. Each helmet is supplied with the clear visor included as standard.
