E-Racing 4

Aware of the constant growth in e-bikes, we have developed the first all-round wheel specifically for this market segment. We have a proven track record in the E-MTB world and we have applied this technical expertise to the latest evolution of current bikes and new way of cycling. 

We began by developing a specific rim profile, with an inner rim width of 22 mm (ideal for tyres between 30 and 45 mm), special self-locking long head nipples and project-specific spokes. As we discovered when we developed the E-MTB wheels, the motor increases the load on the freewheel, which has to support greater torsional loads for longer periods too. This is where we focused our attention. Seeing as the freewheel body is the contact point where the drive force is transferred from the cassette to the wheel body, it is subject to higher stresses due to the increased power and jerks caused by the activation of the motor. This led us to use a tempered steel freewheel body, with specific internals, able to support a tensile strength greater than 30%. The results of lab analysis on the behaviour of the single pawls on cycles higher than a billion are clear: the life of cemented steel is estimated to be 2 times higher than Ergal models used for traditional road models.
