Fulcrum E-Racing 4 DB Wheelset - Clincher - Centerlock - FW: 12x100mm | RW: 12x142mm - Shimano/SRAM HG Freewheel

All-round wheelset specially developed for E-Road and E-Gravel. Fulcrum began by developing a specific rim profile, with an inner rim width of 22mm (ideal for tyres between 30 and 45mm), special self-locking long head nipples and project-specific spokes. As they discovered when they 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 Fulcrum focused their 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 Fulcrum to use a tempered steel freewheel body, with specific internals, able to support a tensile strength greater than 30%.
