DESCRIPTION

  • ㆍConventional derailleur systems rely on externally exposed components, which inherently suffer from chain drop, contamination, frequent maintenance, and reduced durability :
    ATB-P fundamentally addresses these limitations by adopting a fully sealed gearbox architecture.

    ㆍATB-P uses the same fixed-input 1×7 architecture as ATB-L :
    The input gear between the pedal shaft and the main shaft is configured with a 54:30 ratio, increasing rotational speed while reducing the transmitted torque.

    ㆍThis input structure provides several practical advantages.

    ㆍFaster gear engagement :
    The increased rotational speed accelerates the engagement between the pawls and the internal gear teeth, significantly reducing pedal free-play and engagement delay.

    ㆍImproved shifting durability :
    By reducing the torque transmitted to the main shaft and shifting components, long-term durability is naturally improved.

    ㆍThe key difference from the ATB-L version lies in the use of high-strength, heat-treated alloy gears :
    Thanks to the fixed input structure, ATB-P achieves durability that exceeds even that of the ATB12, despite its simpler architecture

    ㆍThis enhanced durability allows the gearbox to be designed with thinner gears, enabling a lighter overall structure without compromising strength.

ATB7-P (Premium)

  • Application Advantages

    ㆍDownhill bikes :
    In downhill riding, the number of gears actually used is limited. ATB-P can therefore be applied as a lightweight gearbox solution while still providing exceptional durability

    ㆍE-cargo bikes :
    With its high mechanical strength, ATB-P pairs exceptionally well with powerful hub motors, forming a robust and reliable drivetrain for cargo applications.

    ㆍThis input structure provides several practical advantages

    ㆍUrban commuting :
    Most urban riders do not require a wide gear range. For users who seek higher durability or a more premium feel beyond ATB-L, ATB-P offers a lightweight and reliable alternative.
