High-coverage open-face protection for aggressive trail, enduro and all-mountain riding.
The Ride Concepts Dissent Mips® Helmet is built for riders tackling rough terrain, enduro stages and bike park laps. Its durable four-piece shell provides extended coverage, while oversized ventilation and a secure fit system help keep it comfortable when the riding gets demanding.
Mips® Evolve Core, a Fidlock® magnetic buckle, anti-odour padding and a goggle-friendly visor give the Dissent the protection, comfort and practical features expected from a premium aggressive-trail helmet.
Extended Trail Coverage
A lightweight four-piece polycarbonate shell is combined with in-mould EPS construction to help manage impact energy. Full lower hard-body coverage improves durability around the exposed lower edge of the helmet, making the Dissent well suited to rougher trail and enduro riding.
Mips® Evolve Core
The Mips® Evolve Core system is designed to help reduce rotational motion transferred to the head during certain angled impacts. It sits inside the helmet while allowing the retention system and padding to maintain a secure, comfortable fit.
Secure, Adjustable Fit
The shell-integrated FS6™ fit system uses a micro-adjust dial to fine-tune the fit. Quick-release strap adjusters make setup straightforward, while the Fidlock® magnetic buckle provides fast, secure fastening that can be operated with one hand.
Ventilation for Demanding Rides
Fifteen oversized vents work with internal airflow channels to move air through the helmet. This helps manage heat during enduro transitions, sustained climbs and warmer bike park laps.
Goggle-Friendly Visor
The multi-position visor can be adjusted for different riding conditions and provides space for goggle storage when they are not being worn. Ride Concepts’ Link™ system gives the visor a secure mounting point for rough terrain.

Dissent or Deploy?
Choose the Dissent if you want additional shell coverage, a more integrated fit system and premium features for aggressive trail, enduro and bike park riding.
For trail and cross-country riding where lower weight and maximum airflow are the priority, consider the Ride Concepts Deploy Mips® Helmet.
Who Is It For?
The Dissent suits riders who spend their time on rough singletrack, steep descents, enduro stages and bike park trails but still want the ventilation and freedom of an open-face helmet. It is a good match for longer-travel trail and enduro bikes.
This is an open-face helmet. For downhill riding, racing or terrain where additional face and jaw protection is appropriate, choose a properly certified full-face helmet.
Our Thoughts
The Dissent sits at the more protective and feature-rich end of the open-face trail helmet category. The deep coverage and four-piece shell give it a substantial feel, while the large vents prevent it from becoming overly hot on climbs. The Fidlock® buckle, X-Static® padding and secure visor mount are useful upgrades for riders who spend plenty of time on rough terrain.
Important Fit Advice
Measure around the widest part of your head, sitting approximately 2 cm above your eyebrows, then compare the measurement with the size guide. The helmet should sit level and feel snug without creating pressure points. Adjust the rear retention system and straps before every ride.
Replace the helmet after a significant impact, even if there is no visible damage.
