The E-Racing 4 Center Lock Disc Wheelset in 28″ was Designed for E-Bikes
The Fulcrum E-Racing 4 Center Lock Disc wheelset is a true all-rounder for all 28″ road and gravel bikes with electric drivetrains. The higher weight of E-bikes leads to greater stress during braking, but also during propulsion. For this reason, the rims and spoke heads have been reinforced. The freehub body and pawls are also made of sturdy, hardened steel. The relatively large rim width of 22 mm allows you to use wider tyres from 30 mm. This means that you are not only fast, but also extremely comfortable on the road. The asymmetric rim design is designed to accommodate and balance the unilateral forces of the cassette and disc brakes. The rims of the E-Racing 4 wheels are also 2-Way-Fit-Ready. This means that you decide for yourself whether you want to ride tubeless or stick to tubular tyres.
Guidelines for Replacing E-bike Components:
Before you replace components on your E-bike, please read the guidelines for component replacement for CE-marked E-bikes, pedelecs with pedal assistance.
