The Pro SL helmet builds on the success of our award-winning, flagship MT500, bringing the enhanced protection of a full Koroyd core to the road rider. Low weight, exceptional ventilation, a host of novel features and stunning looks come together in this premium road helmet.


Integrated into the core design of the Pro SL Cycle Helmet, Koroyd's engineered tubes absorb energy in a more linear fashion than traditional mountain bike helmets. In the event of impact, the Koroyd tubes crush homogenously, absorbing g-force created by the rider’s momentum and lowering the chance of injury.


The Pro SL meets the Koroyd Safety Initiative which sets voluntary lower limits to outperform standard helmet safety requirements. The KSI limits for maximum deceleration and HIC significantly reduce the correlated risk of severe head injuries in real life accidents. Looking at peak g values the KSI limit of 183g reduces the risk of fatal skull fracture to less than 5% from a suprsingly high 40% at the levels required to meet CE certification.


The Koroyd core also allows a more open structure to promote airflow, while the tubes of Koroyd structure within the vents maintain a linear flow of air to maximise breathability, cooling and comfort.


If you’re unfortunate enough to be involved in an accident that causes damage to your Endura helmet, our Helmet Crash Replacement Scheme will reduce the cost of replacing your helmet with the same model or nearest model.
