Overview

Ideal for commuters, recreational road riders and gravel or MTB riders who want a comfortable, lightweight helmet with a secure fit and versatile styling.

The Sintesi is the helmet we recommend when you want one dependable lid for road riding, gravel, MTB and urban commuting. Its smooth, understated shape works across different types of riding, while the EPS inner shell and polycarbonate outer shell combine a protective core with a durable finished exterior. At 230 g in size M, it feels unobtrusive without looking or feeling like a bulky commuter helmet.

Fit is a major strength. The Ergo Fit adjustment system provides precise micro-adjustments, while the rear retention cradle can be positioned to suit your head shape. The result is a stable, comfortable fit that stays settled over rougher surfaces and longer rides. Breathable Blue Tech padding adds antibacterial and antistatic properties for comfortable everyday use.

The Sintesi uses 13 generous vents, but its airflow is more moderate than that of a highly ventilated race helmet, particularly on slow, hot climbs. It also does not include a dedicated place to dock sunglasses in the front vents. For riders prioritising comfort, versatility, low weight and a polished look over outright aerodynamics or maximum ventilation, the Sintesi is a well-rounded choice.

WG11 rotational impact testing

KASK’s WG11 protocol tests the helmet against rotational impacts, adding a further layer of testing beyond the required CE / UKCA - EN 1078 standard.

Lightweight everyday feel

The published 230 g size M weight keeps the helmet comfortable and unobtrusive across commutes, training rides and longer adventures.

Precise Ergo Fit adjustment

The rear adjustment wheel enables fine tension changes, while the adjustable retention cradle helps you achieve a secure, personalised fit.

EPS and polycarbonate construction

An EPS inner shell and polycarbonate outer shell provide a lightweight protective structure with a durable outer finish.

Blue Tech padding

Breathable padding with antibacterial and antistatic properties helps keep the helmet feeling fresher through regular use.

Multi-surface versatility

The Sintesi is designed for road, gravel, MTB and urban commuting, making it a practical choice when you want one helmet for several riding styles.

Moderate ventilation

Thirteen vents provide airflow for everyday riding, although riders who regularly climb slowly in very hot conditions may prefer a more heavily ventilated race helmet.

Clean, understated profile

The smooth, rounded shape looks discreet across road, gravel and city riding, without the bulky appearance of some commuter-focused helmets.
