In addition to the standard filter version, BMC has developed another filter option.
This is the "Carrera" filter, which is a filter that is consistent in shape with the standard filter, but has been constructed from filter material to provide increased airflow over other filter systems, while also maintains the filtering effect.
BMC's "Carrera" filter is designed for those who are not satisfied with the normal performance of the bike, but modify the engine and control unit to achieve more power afterwards. The "Career" filter can be recognized by a yellow stripe.
