Choose a lubricant specifically designed for bicycle chains and apply it generously to the chain, ensuring it penetrates all the links. Let the lubricant sit for a few minutes to allow it to penetrate, then wipe off any excess with a clean rag. Regularly lubricating your chain will prolong its lifespan and improve your bike’s performance.
3.3. Fixing a broken chain
A broken chain is a common issue that can happen while cycling, but it doesn’t have to be a ride-ending problem. To fix a broken chain, start by removing the broken link using a chain tool. Then, insert the ends of the chain into a quick-link, making sure they are properly aligned. Use the chain tool to push the quick-link together until it clicks into place. Give the chain a few rotations to ensure it’s securely connected.
3.4. Replacing a chain
If your chain is severely worn or damaged, it may be time to replace it entirely. To replace a chain, use your chain tool to remove the old chain, paying attention to the length and routing of the chain. Thread the new chain through the derailleurs and around the cassette, making sure it is properly tensioned. Use your chain tool to connect the ends of the chain using a quick-link or by inserting a chain pin and securing it with the tool.
4. Adjusting Brakes
4.1. Checking brake pad wear
Properly functioning brakes are crucial for your safety, so it’s important to regularly check the wear on your brake pads. Look for indicators or lines on the brake pads that tell you when they need to be replaced. If the pads are worn beyond the indicators or have become uneven, it’s time to replace them.
4.2. Adjusting brake pad position
If your brake pads are not properly aligned with the rim or disc, they may not provide adequate stopping power. To adjust the brake pad position, locate the adjustment screws on your brake calipers. Loosen the screws and position the brake pads so they are parallel to the rim or disc, ensuring even contact when the brakes are applied. Once the pads are properly positioned, tighten the adjustment screws.
4.3. Aligning brake calipers
If your brakes are rubbing against the rim or disc even when not in use, you may need to realign the brake calipers. Start by loosening the mounting bolts that hold the caliper in place. Squeeze the brake lever to engage the brakes and hold it in position. While holding the lever, tighten the mounting bolts, ensuring the caliper is centered and the pads are equidistant from the rim or disc. Release the brake lever and check that the pads are no longer rubbing.
4.4. Adjusting brake cable tension
If your brakes feel too loose or too tight, adjusting the brake cable tension can help improve their performance. Start by locating the barrel adjuster on your brake caliper or brake lever.

5. Fixing Gear Shifting Issues
5.1. Diagnosing gear shifting problems
If your gears are not shifting smoothly or are skipping, it’s important to diagnose the problem before attempting any adjustments. Common causes of shifting issues include cable tension, limit screw misalignment, or a bent derailleur hanger. Observe how the gears are behaving and listen for any unusual noises to help pinpoint the issue.
5.2. Cable tension adjustments
Imbalanced cable tension can cause gears to shift poorly. To adjust the cable tension, start by shifting to the smallest chainring and the smallest rear cog. Locate the barrel adjuster on your rear derailleur and turn it counterclockwise to increase tension or clockwise to decrease tension. Make small adjustments and test the shifting after each turn until the gears shift smoothly through all gears.
5.3. Limit screw adjustments
Limit screws determine the range of motion for the front and rear derailleurs, preventing the chain from moving too far in either direction. To adjust the limit screws, first, shift to the smallest chainring and smallest rear cog (for front derailleur) or largest chainring and smallest rear cog (for rear derailleur). Begin by adjusting the lower limit screw, turning it counterclockwise to allow the chain to move closer to the frame or clockwise to prevent it from rubbing against the frame. Repeat the process for the upper limit screw, ensuring the chain moves smoothly without dropping off the chainring or cassette.
5.4. Rear derailleur hanger alignment
If your gears are still not shifting smoothly, a bent derailleur hanger may be the culprit. To align the derailleur hanger, you will need a derailleur hanger alignment tool. Start by attaching the tool to the derailleur hanger and carefully aligning any bends or misalignments. Make small adjustments and test the shifting after each correction until the gears shift smoothly and positively.
6. Fixing a Bent or Broken Wheel
6.1. Assessing the damage
A bent or broken wheel can make cycling difficult and unsafe. The first step in fixing a damaged wheel is to assess the extent of the damage. Spin the wheel and observe any wobbling or rubbing. Look for visible signs of damage such as bent spokes or cracks in the rim. Depending on the severity of the damage, you may be able to fix the wheel temporarily or need to seek professional assistance.
6.2. Truing a wheel
When a wheel is slightly out of true, meaning it has a slight wobble or uneven tension in the spokes, it can often be fixed by truing it. To true a wheel, you will need a spoke wrench. Start by identifying any loose spokes or areas of uneven tension. Gradually tighten or loosen the appropriate spokes to reposition the rim until it is centered and no longer wobbling. This process requires patience and practice, so start with small adjustments and test the wheel frequently.
6.3. Replacing a broken spoke
If a spoke has broken, it’s important to replace it before attempting to true the wheel. To replace a broken spoke, start by removing the damaged spoke using a spoke wrench. Measure the length of the broken spoke to ensure you purchase a replacement of the correct length. Thread the new spoke through the spoke holes in the hub and rim, making sure it crosses the appropriate number of spokes. Use the spoke wrench to tighten the spoke until it has the same tension as the surrounding spokes. Finally, true the wheel to ensure it spins evenly.
6.4. Recognizing when a wheel needs professional attention
In some cases, a bent or broken wheel may be too severe to fix on the trail. If you notice significant cracking, severe bending, or multiple broken spokes, it’s best to seek professional help. A bike shop can assess the damage and recommend the best course of action, whether it’s wheel rebuilding or replacement.
7. Basic Suspension Tuning
7.1. Adjusting suspension sag
Suspension sag refers to the amount of travel your suspension has under your weight when you’re sitting on the bike. To adjust suspension sag, start by measuring the sag using a sag indicator or zip ties on the stanchion. If the sag is too high, add air pressure to the suspension. If the sag is too low, release air pressure. Consult your suspension manufacturer’s guidelines for recommended sag percentages and adjustments specific to your bike’s suspension system.
7.2. Adjusting rebound
Rebound refers to the rate at which your suspension extends after compression. To adjust rebound, start by finding the rebound adjuster on your suspension fork or shock. Gradually turn the adjuster clockwise to slow down the rebound or counterclockwise to speed it up. Experiment with different settings to find the rebound speed that suits your riding style and terrain conditions.
7.3. Fine-tuning compression
Compression adjustments control how your suspension reacts to impacts. High-speed compression affects heavier impacts, while low-speed compression controls smaller bumps and undulations. Consult your suspension manufacturer’s guidelines for adjusting compression and experiment with different settings to find the optimal setup for your riding style and trail conditions.
