THE HUB
The over-size hub flange and 25mm axle to prvent axle deformation too much.EZO bearing from Japan is very smooth and durable.EXCELLENT DESIGN
In order to achieve better acceleration performance and relatively high rigidity. Reduce the left and right tension ratio taking by the bigger drived side hub flange to increase wheel stiffness and durability , 15mm axle in front wheel to make lighter and better performance.
