KMC 104pcd 4 Arm Narrow/Wide E-Bike Steel Chainrings Black 38T 4 Arm
Reinforced chain construction handles higher e-bike torque for lasting use
Sold and shipped by Le Coq Wielerartikelen FR
The KMC e-bike chainring is built specifically for the demands of electric drivetrains, where consistent power transfer and durability matter even more than on a standard setup. Constructed from quality steel and designed for 104 BCD 4-arm spider cranksets, it ### Features the same narrow-wide tooth profile that defines KMC's chainring range, with alternating tooth widths providing secure chain retention even under the increased torque and load that motor assistance puts through the drivetrain. The steel construction is specifically chosen here over aluminium to handle that additional stress reliably over the long term, while also delivering maximum efficiency that helps preserve battery life rather than wasting power through unnecessary drivetrain friction. Perfectly matched to KMC chains, it covers e1, e8, e9, e10, e11 and e12 speed configurations, though it is not compatible with 12 or 13-speed flattop chains. A dependable, purpose-built upgrade for any e-bike rider who wants their drivetrain to keep pace with their motor.
