A helmet is essential for any rider. Designed to soften impacts to the brain of a cyclist in falls while minimizing side effects such as interference with peripheral vision. The dominant technology is currently in-mould microshell. A very thin shell is incorporated during the moulding process, allowing for larger vents and more complex shapes than previous helmets. The Raleigh RSP Sphere helmet features 18 channelled airflow vents to force cool air in and warm air out. It can be quickly adjusted by a small dial situated at the rear of the helmet. The side straps can be adjusted by cam locks on either side. Nexus chin buckle and sealed inner pads also ensures perfect custom sizing for every rider. Its stylish aerodynamic design is enhanced with a detachable visor and vivid colours. Very good entry level lightweight helmet.
