Wheel alignment (also called truing) involves: checking that the wheel spins freely without wobbling, identifying any bent or loose spokes, using a spoke wrench to tighten or loosen spokes to bring the wheel back into proper alignment, ensuring the wheel is centred in the frame and does not rub against the brake pads, and checking that the axle is properly seated in the frame dropouts. Proper alignment ensures smooth riding and even wear on tyres and brake pads.
