ㆍATB12 is a high-performance 12-speed gearbox designed to deliver premium gearbox performance at a rational and accessible price point.
ㆍOver the years, various internal gear hubs and gearboxes have been introduced to the market. While technically advanced, many of these solutions have remained limited to niche segments due to their high cost.
ATB12 was developed to remove this price barrier while preserving true high-end performance.
ㆍWith 12 speeds and a gear range exceeding 575 percent, ATB12 offers more than sufficient coverage for demanding riding conditions, without
compromise.
ㆍATB12 adopts a 6×2 architecture, in which six main gears are combined with a two-stage output configuration.
ㆍThanks to the second-stage gear combination, the output shaft operates at higher rotational speed and lower torque.
This characteristic significantly reduces load on the belt drive, resulting in extended belt service life.
ㆍThis output behavior provides clear advantages not only for MTB riding, but also for long-distance and touring applications where drivetrain efficiency
and durability are critical.
ㆍATB12 is fully capable of handling aggressive MTB riding, yet it truly excels as a touring gearbox.
The architecture minimizes the number of highly stressed components, resulting in an exceptionally low probability of mechanical failure.
ㆍIn addition, the use of cost-efficient components ensures that replacement parts remain affordable, keeping long-term maintenance costs low.
ㆍThis input structure provides several practical advantages
ㆍWhen compared to high-end derailleur systems, which often require frequent and costly maintenance, the value of ATB12 becomes even more apparent.
ㆍATB12 is not merely an alternative to premium derailleur systems in terms of performance. It represents a fundamentally different approach, prioritizing durability, efficiency, and total cost of ownership.
By combining high gear range, mechanical efficiency, and low maintenance requirements at a rational price, ATB12 makes high-performance gearbox
technology practical for a much wider range of riders.
