What’s the difference between MIPS and WaveCel?
KEY TAKEAWAY
The main difference between MIPS and WaveCel is that MIPS reduces rotational forces only. WaveCel reduces rotational and linear forces.
There is no objective testing that would determine which one of these technologies is more effective. However, both provide better protection than helmets without these technologies.
However, there are other bicycle helmet safety systems that you should know about. You can learn more about them below.
Additionally, I had the opportunity to interview Max Strandwitz, the CEO of MIPS, and ask him a few questions to better understand MIPS.
Let’s dive in.
Popular Helmets Safety Technologies
You may have heard about one of the following three safety technologies:
- MIPS
- WaveCel
- SPIN
Below, I explain them further and help you understand their benefits.
1. MIPS
MIPS (Multi-directional Impact Protection System) is the most popular of all systems mentioned in this article. It was adopted widely by helmet manufacturers like Giro, Bell, Specialized, and many more.
This technology has been in development for more than 20 years. The MIPS technology reduces the rotational forces that arise during an impact and the risk of brain injuries.
How does MIPS work?
The Mips® safety system features a low-friction layer inside the helmet that allows a multi-directional movement of 10-15mm on certain angled impacts, intended to help reduce rotational force to the head. (Source)
You can watch the following video to see the visualization.
MIPS Pros
- Reduces rotational forces
- Integrated into helmets of many brands
MIPS Cons
- Adds about 0.88-1.59oz. (25-45g) to the bike helmet*
- Does not reduce linear forces
*This estimation is based on the same size and model of a helmet with and without MIPS
I asked MIPS’ CEO, Max Strandwitz, what they plan for the future and if they will also focus on reducing the linear forces like WaveCel with their system. Here are his answers:
We always look for better product integration and to develop new solutions to enable integration in even more helmets.
Our focus so far has been to redirect rotational forces that is where we have spent a lot of our research and where our key competence has been.
If you’re wondering if MIPS will develop its own helmet. I’ll disappoint you. According to Mr. Strandwitz, that’s not the direction they plan to go.
2. WaveCel
WaveCel is a cellular structure inside a helmet that reduces linear and rotational forces. (Source)
The WaveCel technology is exclusive to Bontrager helmets and differs from MIPS and SPIN. Its goal is to reduce the rotational and linear forces and the risk of a brain injury.
How does WaveCel work?
Trek explains the WaveCel technology in 3 steps:
- Flex – reduces the initial frictional forces.
- Crumple – reduces the impact forces.
- Glide – the WaveCel redirects the energy away from your head.
You can watch the following video to learn more.
WaveCel Pros
- Reduces rotational forces
- Reduces linear forces
WaveCel Cons
- Adds about 1.76oz. (50g) to the bike helmet
- WaveCel technology is used on Bontrager helmets only
- Bontrager helmets with WaveCel are more expensive on average than helmets with MIPS or SPIN
3. SPIN (Is Being Phased Out)
SPIN (Shearing Pads INside) is a safety technology developed by bicycle helmet manufacturer POC and patented in 2017. POC started to use it in its helmets in 2018. (Source)
MIPS and SPIN are two very similar technologies. Due to the SPIN’s similarity with MIPS, POC had legal troubles.
However, they are working together to develop a system combining the best of both technologies. (Source) Therefore, SPIN is gradually being phased out since 2021.
How does SPIN work?
SPIN uses so-called SPIN pads that reduce rotational and linear forces (MIPS uses an additional layer).
Check out the following visualization.
SPIN Pros
- Reduces rotational forces
- Reduces linear forces
SPIN Cons
- SPIN technology is used on POC helmets only
| Technology | Pros | Cons |
|---|---|---|
| MIPS | • Reduces rotational forces | • Adds about 0.88-1.59oz. (25-45g) to the bike helmet* • Does not reduce linear forces |
| WaveCel | • Reduces rotational forces • Reduces linear forces | • Adds about 1.76oz. (50g) to the bike helmet • WaveCell technology is used on Bontrager helmets only • Bontrager helmets with WaveCell are more expensive on average than helmets with MIPS or SPIN |
| SPIN** | • Reduces rotational forces • Reduces linear forces | • SPIN technology is used on POC helmets only |
*This estimation is based on the same size and model of a helmet with and without MIPS
**SPIN technology is gradually phased out since MIPS and SPIN joined forces in 2021.

Other Less Known Helmets Safety Technologies
There are also other safety technologies used by other manufacturers. To name a few:
- Fox Fluid
- Turbine Leatt
- Kali Protectives
- Koroyd by Smith
- SHRED
- KinetiCore
All these technologies aim to reduce the rotational and/or linear forces to provide more effective protection.
Summary
All bicycle helmets legally sold must meet minimum safety criteria, such as those from CPSC, to provide sufficient head protection.
However, safety systems like MIPS, WaveCel, SPIN, and SHRED further reduce rotational forces that can lead to brain injury.
While few tests compare these technologies under the same conditions, available data shows they compete on a similar level to improve your safety as expected from a bicycle helmet.
Any thoughts on the 6DF helmet’s technology? They did receive an NFL grant for further study…
Hi Richard, I wrote this article last year, so if there has been any recent news regarding the 6DF, I haven’t had a chance to investigate it further.
Thank you for your understanding.
