The Deda Elementi Trentacinque stem and its matching handlebar M35 are the greatest innovation of the last years in the field of road racing bicycle components. Thanks to a larger diameter it creates a much higher level of stiffness for the stem and handlebar, so defining a new benchmark for the market. This higher level of stiffness also means that there is a much less of a riders energy being lost through flexible components. Meaning they can put more power through the bike without worry of lost energy.
