Decathlon | Road Cycling Helmet RCR - Black

This helmet was designed so that the ventilation works perfectly when you needit, on long climbs. As soon as you tip upwards, the aerodynamics of thishelmet will make all the difference. **Key benefits:** * Ventilation: 8 air entrances connected to 7 exits via canals * Lightweight: In-Mold technology results in a lightweight helmet (270 g in size M) * Anatomic design: Turn-ring system for a micrometric adjustment. Occipital adjustment * Aerodynamics: Developed and tested in a wind tunnel to minimise its drag coefficient * Compatibility: Compatible with long hair. Can accommodate a braid.**Technical information:**RCR: The RCR range for RACER is the range intended for cyclists looking forthe best equipment. This range is suited to cyclists looking for excellence onall terrain. Very high-level, versatile products for riding on both flats andin the high mountains. The RCR range has been chosen by the Decathlon AG2R LaMondiale professional team ; SECURITY: Because the main reason for getting ahelmet is to keep yourself safe, this helmet meets all of the most demandingstandards for impacts. It complies with the European regulation EN1078. Thisstandard covers the following aspects: construction, including field ofvision, shock absorption properties, retention system features including thechinstrap and tightening devices, and marking and information. ; Sizes &Weight: The size of a helmet is based on your head circumference. RCR: Size S:52-55 cm - 230 g size M: 55-59 cm - 270 g Size L: 59-62 cm - 290 g This helmetis also available in a version with the MIPS system. This system slightlymodifies the size grid, so if you are at the upper end of the size range andprefer the MIPS version, we recommend purchasing one size higher. ;Ventilation: A helmet's ventilation is optimal when large entrances for airare connected to exits via canals that let the air circulate. The head is anessential component for cooling the body during intensive effort. Theevacuation of the heat generated is thus a priority for maintaining a highlevel of performance. ; VENTILATION AND AERODYNAMICS: Poorly placedventilation can, on the other hand, generate a great loss of aerodynamicperformance by significantly increasing drag. The RCR has a variableventilation system depending on your position on the bike. The straighter upyou are, for instance when climbing a slope, the more effective the system. Assoon as you tip down for a descent, the aerodynamics of this helmet will makeall the difference.
