Re-installing the rear wheel 

Carry out the removal instructions (7-1) in reverse order.
A. Re-install the torque support. Otherwise the frame could be 
damaged.

B. Ensure that the rear wheel is seated centrally in the frame before 
you securely tighten the axle nut with 60 Nm.

C. Ensure that the brake disk is seated properly between the brake 
calipers and that the wheel can turn freely without the brake pads 
dragging against it. 

D. Ensure the chain is seated properly on the chain rings at front and 
back.

E. Fasten the cable clips back to the drop-out and to the frame.

 If this process of setting up and adjusting the brake is not completely clear to you, ask your A2B specialist dealer to adjust the brakes 

of your A2B for you. Improperly adjusted brakes have, among other things, reduced braking performance, which could result in an accident 
with serious injuries or even death and/or property damage. DO NOT use your A2B if you have doubts concerning the proper function of 
the brakes.
