As a subsidiary of a bearing manufacturer ACROS has developed a new bearing for the new Nineteen hub series. This stainless steel angular contact bearings are radically attuned for low weight and simultaneously a high bearing load. Furthermore all NINETEEN hubs feature a 19mm King-Size aluminium axle. Hence they are light and also super stiff. The massive hub shell consists of 7075 aluminium and is equipped with a 6-bolt brake disc mount. The flanges are suited for J-Bend spokes. Hence it is perfectly suited to build durable wheels.
This version is suited for 15x110mm Boost thru axles. A 10mm larger hub flange spacing (compare to 100mm system) increases wheel stiffness and durability. It also fits new "Plus Size" wheels to provide more control and riding efficiency.
Two double sealed (R2 rubber lip seal, R3 specially shaped sealing lip with steel-plate reinforcement), precisely manufactured and purpose-optimized angular contact stainless steel bearings form the heart of the Nineteen FR FW hub and allow the hub to spin play-free and smoothly for a long time.
Additionally "The Clamp System" allows an easy bearing play adjustment.
