BELL Catalyst MIPS Adult Mountain Bike Helmet

MOTIVATION TO RIDE. For riders looking for a lightweight, well-ventilated helmet that's all about going fast, the Catalyst brings an engineered fit and modernized, rounded shape that looks as modern as it feels. With MIPS newly integrated into the Float Fit system, the Catalyst now offers comprehensive energy management while allowing for a sleeker, more comfortable overall fit. Add to this No-Twist Tri-Glides, cooling Overbrow Ventilation, and a removable visor, and the Catalyst is pure motivation to get out there and ride more miles.

• CONSTRUCTION - Integrated MIPS (Multi-Directional Impact Protection System) - MIPS is designed to reduce rotational forces resulting from certain impacts. By integrating the MIPS slip plane into the retention system, we are able to reduce complexity and weight for a compact, better-ventilated helmet that fits more closely to the head.
• FIT - Float Fit - A minimalist, lightweight fit system with an easy-to-turn rubber overmoIded dial for adjustments (integrated with MIPS)
• VENTILATION - Overbrow Ventilation features intake ports on the brow of the helmet to usher in cool air and push it through the air-channel matrix for full-head ventilation. Includes 18 vents.
• FEATURES - No-Twist Tri-Glides: Quick-adjust fasteners that help keep straps flat and properly positioned. Lightweight straps. Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear.
• Size Specifications: Small (52-56 cm), Medium (55-59 cm), Large (58-62 cm) Sizes. Important: always take a head measurement. Head sizes and shapes can vary, even within an age range. Using a helmet that does not fit can be dangerous.
