4.2 Truing the Wheel (Lateral and Radial)

The TS-4.2 features adjustable calipers to detect and correct both lateral (side-to-side) and radial (up-and-down) runout.

• Lateral Truing: Adjust the side calipers until they are close to the rim. Spin the wheel slowly and observe where the rim touches the calipers. Adjust spoke tension (tighten spokes on the opposite side, loosen on the side touching) to pull the rim into alignment.
• Radial Truing: Adjust the radial caliper (typically located at the bottom or top) close to the rim. Spin the wheel and identify high or low spots. Adjust spoke tension (tighten spokes in low spots, loosen in high spots) to achieve a round wheel.

4.3 Adjusting for Tire Clearance

The TS-4.2 is designed to accommodate very wide tires. The caliper arms can be adjusted to provide ample clearance, even with a tire and brake rotor installed.

• Caliper Arm Adjustment: Loosen the appropriate knobs to move the caliper arms away from the wheel, providing clearance for wider tires or rotors.
• Жакшы жөндөө: Once the tire is cleared, reposition the caliper arms closer to the rim for accurate truing.
