Design meets functionality: Purion is the minimalist on-board computer for everyone wishing to have a neat look on the handlebar, be it for use in the city or the countryside. You get all important information conveniently at the touch of a button during the ride, with both hands remaining on the handlebar. Five different riding modes give you the correct support in every situation.
