< In the case of Inter-M brake specifications >
• Attach the brake arm of the Inter-M brake to the chainstay with
the brake arm clip. Then temporarily fix the clip screw and clip
nut by lightly tightening them.
• If the hub nuts are cap nuts, use a frame with dropouts that are
at least 7 mm thick.
• Check that the brake unit is firmly secured to the hub with the
brake unit fixing washer.
3.
Take up the slack in the chain and secure the wheel to the frame with the cap nuts.
• Check that the wheel is fixed securely to the frame with the hub
nuts.
4.
Fix the brake arm securely to the chainstay with the brake arm clip.
Check that the brake arm is securely fastened to the chainstay by
the brake arm clip. If it is not installed correctly, braking
performance will suffer.
• If excessive force is applied to the brake arm to secure it, the
wheel will make noise and become difficult to turn. Make sure
that you don't apply excessive force when installing.
