The Cardo Scala Adaptor will fit into the recess of the Bell Mag-9, previous models and 2015 model, plus the newly redesigned 2015 Qualifier DLX. The Bell adapter fits seamlessly into the helmet and is designed for quick attachment of the highly popular scala rider devices for bike-to-bike intercom, streaming music from a smartphone and much more. With an increasing demand from riders to incorporate communication devices in helmets, Bell Helmets and Cardo Systems, Inc., have designed a convenient adaptor in order to allow users to choose their preferred scala rider model in the Q-Series.
