How to choose the right sizeWith ample protection, great looks and a secure fit, the Quantum is the perfect helmet for those who just want to ride. Featuring Mips technology (Multi-directional Impact Protection - absorbing forces coming from different directions), the helmet has excellent ventilation, making it an ideal choice for both trail and city use.
The Mips (Multi-Directional Impact Absorbing Protection) head protection system, developed by neurosurgeons and scientists, helps to minimise the impact of rotational forces that occur when the head is struck from different angles.
- Mips head protection system.
- The BOA® wheel fastening system allows for easy one-handed fit and adjustment of the helmet.
- Shaped composite shell improves integrity and offers wider ventilation options.
- Lining is soft and comfortable, moisture-wicking and washable.
- Internal vents provide airflow around the head, dissipating excess heat and keeping it dry.
- Removable snap-on visor and vent plugs offer flexibility to fit your style.
- LockDown strap tabs allow easy adjustment of helmet straps.
- In the event of damage in a crash, the Crash Replacement Guarantee program offers free helmet replacement during the first year of ownership.
