Protective mountain bike helmet BELL SPARK 2 — size S/M (52–57 cm), Matte White, no MIPS

BELL SPARK 2 is a protective mountain bike helmet in size S/M (52–57 cm) finished in Matte White. Designed for trail and all-mountain riding, the helmet features in‑shell construction that integrates the outer shell with the impact-absorbing liner for consistent protection and durability. The design includes an adjustable fit system and ventilation channels to promote airflow during rides. This model does not include a rotational protection system (MIPS) and is intended for everyday trail riding and recreational mountain biking.

Advantages

The helmet combines a lightweight in‑shell build with internal padding and an adjustable retention system to provide a secure, personalized fit for riders in the 52–57 cm head size range. Ventilation channels help manage heat and moisture, while the matte white finish offers a neutral aesthetic that pairs with a variety of riding gear. The absence of a rotational protection system simplifies construction and reduces weight.

Suitable for

• Trail riding and singletrack

• Daily training rides and local bike park laps

How to use

Place the helmet on your head so the front rim sits just above your eyebrows. Adjust the retention dial until the helmet feels snug but comfortable, and use the side straps to form a V just below each ear; secure the buckle under the chin and tighten until two fingers can fit between the strap and your chin. Ensure the ventilation openings are not obstructed. Replace interior pads or adjust them to improve comfort. Inspect the helmet before each ride for cracks, significant impacts, or damaged straps and replace the helmet after any moderate or severe impact.

Usage recommendations

For optimal performance, choose the correct size (S/M for 52–57 cm) and maintain the helmet by cleaning the shell with mild soap and water and washing pads as needed. Store the helmet away from direct sunlight and extreme heat. Do not attempt to repair a helmet after an impact; replace it to ensure continued protection.
