MIPS, or, Multi-directional Impact Protection System, was developed by biomechanical specialists at the Royal Institute of Technology Stockholm, Sweden. MIPS is a form of slip plane technology, meaning that a MIPS helmet is constructed from two layers that rotate against each other, mimicking the rotation of the brain’s own cerebrospinal fluid, which is the body’s natural defense against impacts.
The outer layer of a MIPS helmet is made from the same impact-absorbing EPS material as a conventional helmet. It is then connected via an elastic attachment system to a low friction inner layer, which is what rests on the rider’s head.
In a crash, the outer shell of a MIPS helmet absorbs linear impact, while the inner layer rotates up to 5mm, absorbing rotational impact. This small rotation of the liner relative to the shell results in a signification reduction of the forces on the brain, which reduces the likelihood of concussion and other brain injury. MIPS helmets, therefore, provide an extra degree of safety for all bike riders.
We now have a selection of Bell helmets with MIPS. Take a look.
