KinetiCore Protection Explained
Unlike traditional rotational protection systems that add an extra liner inside the helmet, KinetiCore is built directly into the helmet itself.
Specially designed controlled deformation blocks inside the EPS foam are engineered to help manage both direct and rotational forces during certain impacts while also creating larger ventilation channels.
This means the helmet is:
- Lighter
- Better ventilated
- Uses less plastic
- Simpler construction
- More environmentally conscious
without sacrificing everyday comfort.
Lightweight Comfort You'll Forget You're Wearing
One of the first things riders notice is just how light the Tonic feels.
The in-mould construction keeps unnecessary weight down while maintaining excellent strength, making longer rides noticeably more comfortable.
Compared to the previous Tonic MIPS version it is:
- 4% lighter
- Uses approximately 10g less plastic
making it both lighter and more sustainable.
Stay Cool with 28 Large Air Vents
Long climbs...
Hot summer rides...
Indoor trainer warm-ups...
The Tonic's 28 strategically positioned vents channel fresh air through the helmet to keep your head cool.
The open internal design also allows heat to escape efficiently, helping improve comfort throughout long rides.
Independent reviewers consistently praise its ventilation, especially considering its price.
Fast, Easy Fit Adjustment
Every rider has a different head shape.
The Lazer Advanced TurnSys System makes finding the perfect fit incredibly simple.
A rear dial tightens an adjustable head basket that wraps around much of the back of your head, producing a secure fit without pressure points.
Need to adjust it during your ride?
Simply turn the dial.
No complicated straps.
No fiddly mechanisms.
Just quick, precise adjustment.
Eyewear Friendly Design
Need somewhere to put your sunglasses on a long climb?
Integrated docking slots allow most cycling glasses to be securely stored in the helmet while you're riding.
A simple feature that makes a big difference.
Optional Rear LED Light
Increase your visibility during winter rides or commuting by fitting the optional Universal Lazer LED light using the integrated Direct Mount system.
No straps.
No cable ties.
Just a clean, secure fit.

FAQ
Is KinetiCore better than MIPS?
KinetiCore takes a different approach by integrating rotational impact management directly into the helmet structure rather than using an internal slip liner. This allows Lazer to reduce weight, improve ventilation and use fewer materials while still providing rotational impact protection. Both systems aim to reduce rotational forces in certain impacts but use different engineering solutions.
Is the Tonic KinetiCore suitable for road cycling?
Absolutely. It has been designed specifically for road riding but is equally suitable for commuting, fitness riding and gravel adventures.
Can I fit a rear light?
Yes.
The Tonic is compatible with the Universal Lazer LED rear light using the integrated Direct Mount.
Is it comfortable for long rides?
Very much so.
Its low weight, excellent airflow and secure TurnSys fit system make it a comfortable option for rides lasting several hours.
Can I store sunglasses in the helmet?
Yes.
Integrated docking slots securely hold compatible cycling glasses when not in use.

The Tonic KinetiCore hits a real sweet spot. It delivers the comfort, ventilation and fit you would expect from a much more expensive helmet, while keeping the price firmly in the affordable category. For riders who want trusted protection without overspending, it's one of the standout choices available today.
