  • Blackspire E-Bike Chainring

    This chainring has been designed and engineered to offer exceptional shifting performance when used onboard an E-Bike drivetrain. The shift pins have been strategically placed to guarantee consistent shifting in any circumstance.

    Effortless and Crisp Shifting Performance:

    Whether being driven by the motor or the rider, these chainrings are intended to perform to an exceptional level. The outer and middle rings have been specifically designed to feature custom engineered shift ramps that provide accurate, effortless and crisp shifting performance.

    Increased Durability:

    Due to the high forces an E-Bike motor creates and applies to drivetrain components, a standard cycling chainring is not an ideal option. With durability in mind this chainring has been made from 7075 aluminium and tempered (T6) to increase its durability. Blackspire has selected high quality stainless steel when creating the shift pins to guarantee smooth and accurate shifting performance, especially when under load from the E-Bike motor.

    Features:

    • Material: 7075-T6 Aluminium
    • Outer and Inner Ring Thickness: 4.06mm
    • Middle Ring Thickness: 4.83mm
    • Finish: Anodised
    • Drivetrain Speed: 9, 10, 11speed
    • Compatibility: 104mm and 64mm B.C.D. cranks

    Please Note:

    • The 104/38T & 104/40T chainrings are designed for 2x drivetrains
    • To shift correctly the 104/38T requires the use of a 64/24T or 64/26T inner ring
    • To shift correctly the 104/40T requires the use of a 64/26T or 64/28T inner ring
