The Tectal is a well-ventilated helmet designed specifically for aggressive trail biking and enduro racing. It incorporates the Aramid Bridge System and the reinforced EPS liner provides a high level of protection through its unibody construction, which was introduced in the ground-breaking Octal road bike helmet. This manufacturing method further improves the safety features and integrity of the helmet's construction while keeping the weight down. The Tectal encloses the head over a larger area than is the case with conventional mountain bike helmets. It has a highly efficient ventilation design that has been tested and optimised through wind tunnel tests. A goggle clip at the back of the head and an easy-to-use size adjustment system guarantee a comfortable and secure fit.
