Mountain Bike Helmet MQ-93 Cross Country Riding with PC Shell and EPS Integrated Moulding

Designed for cross-country mountain biking, the MQ-93 helmet combines a durable polycarbonate outer shell with an expanded polystyrene inner liner using one-piece moulding technology. This construction method bonds the layers together to enhance impact resistance without adding excess weight. The helmet features 21 ventilation holes that promote airflow during strenuous rides, helping to regulate temperature. A high-end adjustment system allows you to dial in the fit across a range of head sizes, and the removable brim and tail let you customise the helmet for different riding conditions.

Features and Construction

The MQ-93 is built around a proven safety design that integrates the outer shell and inner foam liner in a single moulding process. This approach helps distribute impact forces more evenly across the helmet structure.

Material and Build

The outer shell is made from PC (polycarbonate), a material known for its strength and resistance to cracking. The inner liner uses imported EPS (expanded polystyrene) foam, which compresses on impact to absorb energy. The one-piece moulding process eliminates the need for glue, creating a unified structure that stays intact during use.

Size and Practical Fit

The helmet comes in two sizes: M fits head circumferences from 54 to 58 cm with an inner width of 17 cm, and L fits 58 to 62 cm with an inner width of 17.5 cm. The high-end adjustment system uses a dial at the back to tighten or loosen the fit quickly, even while wearing gloves. The internal padding provides a comfortable contact surface without adding bulk.

Uses and Placement

While designed primarily for mountain biking and cross-country riding, the MQ-93 is also suitable for road cycling and commuting on mixed terrain. The adjustable fit and removable accessories make it adaptable to different riding styles.

Cross-Country Riding

The helmet’s low-profile shape and 21 ventilation holes are optimised for sustained climbs and fast descents on rough trails. The removable brim shields the eyes from low sun and overhanging branches without obstructing upward vision.

Everyday Cycling

For commuting or recreational riding, the helmet’s lightweight construction (estimated under 300 g based on similar models) reduces neck fatigue. The tail can be left attached for added coverage, or removed for a more streamlined look on paved roads.

Benefits and Buying Value

The MQ-93 offers a practical balance of safety features and customisation options at a competitive price point. Its one-piece moulding construction is a standard feature in modern cycling helmets, providing reliable protection across multiple ride types.

Ventilation and Comfort

With 21 vents arranged in a flow-through pattern, the helmet allows hot air to escape while drawing in cool air from the front. This helps reduce sweat build-up during high-effort rides, improving overall comfort over long distances.

Why Choose This Helmet

The combination of an adjustable fit system, removable brim and tail, and six colour options makes the MQ-93 a versatile choice for riders who want a single helmet for different conditions. The use of imported EPS and PC materials supports consistent impact absorption without sacrificing weight savings.
