To adjust the clearance between the brake pads and the rim
1. Turn the barrel-adjuster located on the brake lever.
• To increase the clearance between the brake pads and rim,
turn the barrel-adjuster clockwise.
• To decrease the clearance, turn the barrel-adjuster counter
clockwise.
2. If the brake pads cannot be adjusted correctly with the
barrel-adjuster, further work is required:
• Loosen the cable-clamp bolt, adjust the cable and tighten the
bolt again.
• Release the cable slightly to increase clearance.
• Tighten the cable to decrease clearance.
• Re-adjust the brake-pad alignment, or take the bicycle to your
dealer.
3.7 Shifter and Derailleur Adjustment
Internal Rear Derailleur Adjustment (Nexus 8 speed)
These systems change gears with a mechanism that is in the
rear hub. Each month, check the internal gear system.
1. Turn the shift-lever to the fourth-gear position.
2. Check the indicator on the rear-hub pulley with the cog joint
bracket. If the red lines are not in alignment, turn the barrel-ad-
juster until they are in alignment.
3. Move the shift-lever to first gear. Then move the lever to
fourth gear. Check the adjustment.
Rim brakes(V-brakes)
Brake modulator
The brakes are equipped with a brake modulator, or “Power modulator.” This device includes a small spring in the brake
tube. As you squeeze the brake lever, you must compress the spring before you can apply full braking power to the rim.
This changes the way the brake feels, makes the application of stopping force more gradual, and also makes the adjust-
ment somewhat more sensitive.
To adjust the alignment of the brake pads on a rim brake
1. Loosen the brake-pad fixing bolt.
2. Align the brake pads as shown in the figure above. Tighten the brake-pad fixing bolts.
3. After you adjust the brake, test it by pulling the lever. Make sure the cable does not slide through the cable clamp, the
brake pads engage the rim at ninety-degree angles, and the brake pads do not touch the tyre.
Hub brakes
A hub brake such as a coaster brake, rollar brake usually requires multiple frame attachments and multiple adjustments.
Due to this complexity and the importance to your safety of having the brake adjusted correctly, we highly recommend that
any adjustment of a hub brake, or removal of the wheel from the frame, only be done by your retailer or manufacturer.
