4fourty bell helmet 4Forty MIPS while Integrated Mips and extended hard Bell 4Forty Air MIPS Helmet

You can't remove the one that's originally there because then the spool would rest on bare metal, and if you add two shims the last one would not be held down and would move freely to become wedged beneath the bearing, that's in addition to the extreme difficulty of manoeuvring the shims up and down the hub of the Saltiga without damaging the two O ring seals

This integral helmet combines highly developed materials with advanced technological innovations and rigorous safety standards

People wear helmets as a precaution, not because they expect to come off their bikes

The waterproof feature also comes into play here, as well as in the pool
