Reinforced freehub system
4X more reliable.
Attention to detail was also paid to the freewheel body system, which is the point of junction and transfer of the driving force from the cogset to the wheel body.
The drastic increase of power and jerks, due to the intervention of the motor, made it necessary to use a freewheel body with tempered steel dedicated gears, which are able to withstand a breaking tension by 30% greater.
The laboratory analysis observed the behaviour of the individual ratchets on cycles greater than one billion of uses: the carburised steel ensures an estimated lifetime that is 4 times longer compared to the Ergal model used for the non-E-Mtb models.
