Replacing a Bicycle Spoke
Spokes break for various reasons like impact, fatigue, or improper tension. When a spoke breaks it can cause the wheel to become out of true, leading to wobbling or rubbing against brake pads. Replacing a broken spoke helps maintain the structural integrity of the wheel and ensures a smooth, safe ride.
How to replace a spoke on a bike wheel:
Remove the wheel: if it's a rear wheel, you may need to disconnect the chain.
Identify the broken spoke: spokes are attached to the hub at the center of the wheel and run out to the rim.
Remove the broken spoke: if the spoke is still attached to the nipple (the small part at the rim), unscrew it using a spoke wrench. If it's broken at the hub, you may need to remove the nipple from the rim to free the spoke.
Prepare the new spoke: make sure you have a replacement spoke of the correct length and gauge for a proper fit.
Insert the new spoke: thread the new spoke through the same holes as the old one, making sure it follows the same path to the hub and rim.
Attach the nipple: screw the nipple onto the end of the spoke at the rim. Use a spoke wrench to tighten it, but not too much—just enough to hold the spoke in place.
Tension the spoke: using a spoke wrench, adjust the tension of the new spoke until it matches the tension of the surrounding spokes. This step may require some trial and error to get right.
True the wheel: once the new spoke is in place and properly tensioned, check the wheel for any wobbles or hops*. Use a truing stand or your bike frame as a reference point to make sure the wheel spins evenly.
Reinstall the wheel: making sure it is securely attached and the chain on the rear wheel is properly engaged.
When a bike tire "hops"
This means that the wheel is not spinning smoothly and evenly. Instead, it seems to bounce or move up and down as it rotates. This hopping motion is often caused by an issue with the wheel's alignment or balance.
Reasons why a bike tire might hop:
Uneven spoke tension: if the tension of the spokes in the wheel is not balanced, it can cause the wheel to become out of true, leading to a hopping motion as it rotates. Use a truing stand or your bike frame as a reference point to adjust the tension of the spokes and correct any wobbles or hops in the wheel.
Bent rim: damage to the rim of the wheel, such as a dent or a bend, can cause the tire to hop as it spins. Check the rim of the wheel for any signs of damage or wear, and replace it if necessary.
Worn tire: a tire that is worn unevenly or has bulges or flat spots can cause the wheel to hop as it rotates. Inspect the tire for any signs of damage, wear, or uneven wear patterns, and replace it if necessary.
Misaligned wheel: if the wheel is not properly aligned in the frame or fork of the bike, it can cause the tire to hop as it spins. Make sure the wheel is properly aligned in the frame or fork of the bike, and adjust it if necessary.
Loose or damaged bearings: If the bearings in the wheel hub are loose or damaged, it can cause the wheel to wobble or hop as it rotates. Inspect the bearings in the wheel hub for any signs of damage or wear.
