Fixing a Flat Tire

A flat tire is one of the most common roadside issues. Here’s how to fix it quickly and efficiently.

Step 1: Safety First

Pull over to a safe location away from traffic. If possible, find a level surface to work on.

Step 2: Remove the Wheel

Release the brakes and use the quick-release lever or wrench to loosen the wheel. For the rear wheel, shift the chain to the smallest cog before removing the wheel.

Step 3: Remove the Tire

Use tire levers to carefully pry one side of the tire off the rim. Insert one lever, hook it onto a spoke, and then insert a second lever a few inches away. Slide the second lever around the rim to remove the tire.

Step 4: Remove the Tube

Once one side of the tire is off, pull out the inner tube. Inspect the tire inside and out for any sharp objects like glass or thorns. Remove anything you find.

Step 5: Inflate the Tube Slightly

Inflate the new or patched tube slightly. This will give it some shape and prevent pinching.

Step 6: Install the Tube

Insert the valve into the rim. Carefully tuck the tube inside the tire, making sure it’s not twisted. Start at the valve and work your way around the tire.

Step 7: Seat the Tire

Use your thumbs to push the tire back onto the rim. Start opposite the valve and work your way around. The last section can be tricky, so use your thumbs and be patient. Make sure the tire bead is seated evenly around the rim.

Step 8: Inflate the Tire

Inflate the tire to the recommended pressure (printed on the tire sidewall). Check that the tire is seated correctly and that the tube isn’t pinched between the tire and rim.

Step 9: Reinstall the Wheel

Place the wheel back into the frame or fork, making sure it’s properly seated. Tighten the quick-release lever or axle nuts securely. Double-check that the brakes are functioning properly.

Repairing a Broken Chain

A broken chain can leave you stranded. Here’s how to fix it on the road.

Step 1: Assess the Damage

Identify the broken link in the chain. If the chain is severely damaged, you might need to remove several links.

Step 2: Use a Chain Tool

Position the chain tool on the pin of the broken link. Turn the handle to push the pin out. Remove the broken section of the chain.

Step 3: Use a Quick Link

If you have a quick link, insert each end of the chain into the two halves of the quick link. Snap the quick link together. Some quick links require pliers to fully close them.

Step 4: Reconnect the Chain

If you don’t have a quick link, use the chain tool to rejoin the chain. Push the pin partially back into the link, leaving it slightly protruding. This will allow the chain to articulate properly.

Step 5: Check the Repair

Make sure the repaired section of the chain moves freely. Shift through the gears to ensure the chain is running smoothly. If the chain is still stiff, use the chain tool to loosen the link further.

Adjusting Brakes on the Road

Brakes that are rubbing or not engaging properly can be dangerous. Here’s how to make basic adjustments.

Adjusting Cable Tension

If your brakes feel loose or spongy, you might need to adjust the cable tension.

Locate the barrel adjuster: This is usually found on the brake lever or the brake caliper.
Turn the barrel adjuster: Turn it counterclockwise to increase tension and tighten the brakes. Turn it clockwise to decrease tension and loosen the brakes.
Test the brakes: After each adjustment, test the brakes to see if they are working properly.

Centering Brake Calipers

If your brake calipers are rubbing on one side of the rim, you might need to center them.

Loosen the caliper mounting bolts: Use an Allen wrench to slightly loosen the bolts that hold the brake caliper to the frame or fork.
Center the caliper: Manually adjust the caliper so that it is centered over the rim.
Tighten the mounting bolts: Once the caliper is centered, tighten the mounting bolts securely.
Test the brakes: Spin the wheel and check that the brake pads are not rubbing on the rim.

Adjusting Brake Pad Position

If your brake pads are not hitting the rim squarely, you might need to adjust their position.

Loosen the brake pad bolts: Use an Allen wrench to slightly loosen the bolts that hold the brake pads to the brake caliper.
Adjust the pad position: Adjust the pads so that they are hitting the rim squarely. Make sure they are not hitting the tire.
Tighten the brake pad bolts: Once the pads are in the correct position, tighten the bolts securely.
Test the brakes: Spin the wheel and check that the brake pads are making good contact with the rim.

Dealing with a Bent Derailleur Hanger

A bent derailleur hanger can cause shifting problems. Here’s how to address it on the road.

Step 1: Identify the Problem

Look at your rear derailleur. If it looks bent or out of alignment, the hanger is likely the issue. Shifting will be difficult or impossible.

Step 2: Straighten the Hanger (Carefully!)

This is a delicate process. Use your multi-tool for leverage. Gently bend the derailleur hanger back into alignment. Be extremely careful, as the hanger can break easily. It’s better to get it close to straight than to risk snapping it off completely.

Step 3: Test the Shifting

After making the adjustment, try shifting through the gears. If it’s still not shifting smoothly, make small additional adjustments until it improves. Remember, this is a temporary fix to get you home.

Step 4: Seek Professional Repair

A bent derailleur hanger is a sign of impact. Even if you manage to straighten it, the metal is weakened. Visit your local bike shop to have it professionally aligned or replaced. A new hanger is relatively inexpensive and will ensure proper shifting performance.

Emergency Gear Cable Fix

If your gear cable snaps, here’s a temporary fix to get you home.

The Problem

Your gear cable has snapped, and you’re stuck in one gear. This isn’t ideal, but you can make it work.

The Solution

Manually set your gears to a middle gear that’s comfortable for riding on flat or slightly inclined roads. Use your hand to push the derailleur into the desired position and then tighten the cable clamp screw to hold it in place.

Alternative for Rear Derailleur

For the rear derailleur, you might need to use the barrel adjuster to fine-tune the position. This ensures the chain stays on the chosen gear.

Ride Carefully

With the gear cable fixed in place, you’ll have limited gear options. Ride carefully and avoid steep hills or fast downhills.
