    • flat design on the highest gear, allowing the rear derailleur remains closer to the frame and the deflection is reduced
    • no beating this derailleur on the chain stays, not even in the tough terrain
    • more accurate and faster shifting
    • lower operating forces thanks to a long deflection arm
    • lower noise level
    • Direct mounting on the derailleur hanger, as it specifically occurs on frame with X12 thru axle. Compatibility with quick release dropouts is still given
