The CS57 No Frame is built with 28 ventilation openings, giving it strong airflow and heat dissipation for long rides in India's summer heat and humidity. The Ionic+ Ag+ antibacterial, odor-control lining also helps keep sweat and odor in check on repeated rides.

Depending on size, the CS57 No Frame weighs approximately between 235g and 260g, keeping it light for long days in the saddle. It uses an advanced magnetic buckle for one-second strap attachment and an HDPE-adjustable rear dial, so you can quickly fine-tune the fit before a ride.

The CS57 No Frame is generally available in S (48-53cm), M (54-57cm), and L (57-61cm) head-circumference sizes, so measure your head just above the eyebrows to pick the closest fit. If you are between sizes, the adjustable rear dial gives you extra room to dial in a secure, comfortable fit.

The CS57 No Frame's frameless, minimalist in-mold construction makes it versatile across road, gravel, mountain, and urban riding, rather than being limited to one discipline. This makes it a practical choice for Indian riders who mix commuting with weekend gravel or trail rides on the same helmet.

Wipe the shell with a soft, damp cloth and remove the padding periodically for a gentle hand-wash, since the Ionic+ Ag+ lining is designed to resist odor but still benefits from regular cleaning, especially in India's humid climate. Let the helmet air-dry completely before storing it to avoid trapped moisture inside the EPS liner.
