Sweet Dissenter MIPS Mountain Bike Helmet

  • Lightweight all-mountain helmet with an in-mold polycarbonate shell construction
  • MIPS technology gives a level of protection from rotational brain injury stemming from oblique impacts
  • Ventilation optimised through digital airflow simulation, with added patent-pending STACC ventilation system
  • Occigrip turn-dial adjustable fitting system, shatter-resistant helmet visor optimises airflow
  • Certification: CE EN 1078, CPSC 1203; Weight: 330 grams

Our View: The Dissenter rides hot on the heels of its bigger brothers in the Bushwhacker series. This model has stripped down functionality and comes in at a lower weight, but still packs a spicy punch. Beneath the Dissenter's low-profile in-mold shell you'll find MIPS as standard, a fully adjustable fitting system and aerodynamic ventilation channels.

"The Dissenter is a bang for the buck helmet, benefiting massively from research and development on our high-end helmets. A single-piece polycarbonate shell, in-mould technology and Sweet Protection´s proven geometry combine to provide all-mountain coverage in a low weight, low profile package. This version is equipped with MIPS for extra brain protection." - Sweet

Sweet Cycle Helmet Technology - In-Mold Construction

In-Mold Construction

In-mold construction is a technique that directly fuses the shock absorbing EPS liner with the polycarbonate shells to create a lightweight and strong structure.

Sweet Cycle Helmet Technology - Mono-Shell Shell Construction

Mono-Shell Shell Construction

Polycarbonate mono shell construction with geometrical shapes to add rigidity in critical areas.

Sweet Cycle Helmet Technology - EPS Liner

EPS Liner

The advanced EPS (Expanded Polystyrene) Liner is constructed with variable bridge and channel volume in order to optimize the overall impact protection performance.

Sweet Cycle Helmet Technology - MIPS


Developed to reduce brain injuries. Allowing the helmet to rotate slightly relative to the head upon impact, the helmet can absorb more rotational forces, adding better protection than helmets not equipped with MIPS.

Sweet Cycle Helmet Technology - Occigrip Turn-Dial

Occigrip Turn-Dial

Easy fit adjustment with a low volume mechanism. Provides a firm and comfortable fit and prevents the helmet from rolling on your head. Adjustable in reach and height. Padded with soft silicone pads.

Sweet Cycle Helmet Technology - STACC Vent


Short for Superficial Temporal Artery Cooling Channel. A front vent, an internal channel and an exhaust vent cools down the temporal artery without exposing your temples - the most vulnerable area of the head.

Sweet Cycle Helmet Technology - DOV: Digital Optimised Venting

DOV: Digital Optimised Venting

Ventilation optimised through digital air flow simulation. This ensures the air flows well through vents and internal channels at different speeds.

Sweet Cycle Helmet Technology - Comfort Pads

Comfort Pads

Molded Comfort Pads with soft and comfortable foam wrapped in an anti-allergenic, moisture wicking fabric. Each helmet is delivered with two pad thicknesses for easy fitting.

Sweet Cycle Helmet Technology - Shatter-Resistant Visor

Shatter-Resistant Visor

Optimises airflow in fixed position. Made of ABS Superlight material. Removable. Extra mounting plugs and branded hole covers included.
