Hex wrench set (2-8mm)	Almost all bolts	NT$200-500
Chain cleaner	Cleaning the chain	NT$150-300
Chain lube (wet or dry)	Chain lubrication	NT$150-300
Pump (with pressure gauge)	Tire inflation	NT$500-1,000
Puncture repair kit	Patching/replacing tubes	NT$100-200
Tire levers × 2	Removing/installing tires	NT$50-100

Recommended Additions

• Cleaning brush set (including a cassette brush)
• Degreaser
• Several rags
• Work gloves
• Bicycle repair stand (convenient for working, but not essential)

Skill 1: Chain Cleaning and Lubrication

The chain is one of the fastest-wearing parts on a bicycle. A dirty chain not only affects shifting smoothness but also accelerates wear on the chainrings and cassette.

How Often Should You Clean It?

• After every ride in the rain: Must be cleaned
• Normal use: Every 200-300 km, or every 2 weeks
• Judgment criteria: When there is visible black grime on the chain surface, it’s time to clean

Cleaning Steps

Step 1: Install the chain cleaner

Clip the chain cleaner onto the lower section of the chain and pour in an appropriate amount of cleaning solution (a dedicated degreaser or diluted dish soap both work).

Step 2: Turn the pedals

Turn the pedals backward to run the chain through the brushes inside the cleaner. Rotate 20-30 times until the chain surface is clean.

Step 3: Rinse

Rinse off the remaining cleaning solution with water. Be careful to avoid directing the water stream directly at the bearings.

Step 4: Dry

Dry the chain with a dry rag, or let it air dry for a few minutes.

Step 5: Apply lube

Drip one drop of chain lube onto the rollers of each chain link, then slowly turn the pedals to distribute the lube evenly. Let it sit for 5 minutes, then wipe off excess lube with a dry rag.

Important: The lube only needs to be inside the chain (between the rollers and pins). Lube on the surface will only attract dust. Be sure to wipe off excess oil from the surface after lubing.

Choosing Chain Lube

• Dry lube: Suitable for sunny, dry conditions; less likely to attract dust
• Wet lube: Suitable for humid, rainy conditions; better durability
• Recommendation for Taiwan: Use dry lube in summer, wet lube in winter or during the northeast monsoon season

Skill 2: Tire Pressure Check and Inflation

Correct tire pressure is the foundation of riding safety and efficiency. Too-low pressure can easily cause snakebite punctures, while too-high pressure results in insufficient grip and poor comfort.

Recommended Tire Pressure

Tire Width	Recommended Pressure (Road Bike)	Recommended Pressure (Mountain Bike)
23C	100-120 PSI	-
25C	90-110 PSI	-
28C	80-100 PSI	-
2.0"	-	30-50 PSI
2.3"	-	25-40 PSI

Lighter riders can run slightly lower pressure, while heavier riders should run slightly higher. The recommended pressure range is usually printed on the tire sidewall.

Check Frequency

• Road bikes: Should be checked before every ride (road bike tire pressure drops faster)
• Mountain bikes/commuter bikes: Check once a week

Valve Types

• Schrader valve: Same as car tires, commonly found on mountain bikes
• Presta valve: Thinner and longer, standard on road bikes. You must unscrew the small nut at the top before inflating.

Skill 3: Patching Tubes and Replacing Inner Tubes

Flat tires are something every rider will encounter. Learning to fix a flat yourself is a fundamental skill.

Steps to Replace an Inner Tube

Step 1: Remove the wheel

Open the quick-release lever or loosen the nuts, then remove the wheel from the frame.

Step 2: Deflate

Completely release any remaining air from the inner tube.

Step 3: Remove the tire

1. Insert a tire lever between the tire and the rim
2. Pry one side of the tire bead over the rim, hooking the lever onto a spoke
3. Use the second tire lever to slide along the rim, prying the entire side of the bead over the rim
4. Remove the old inner tube

Step 4: Inspect the tire

Run your fingers slowly along the inside of the tire casing to check for any sharp objects (glass shards, nails, etc.) embedded in the tire. If you find any, be sure to remove them.

Step 5: Install the new inner tube

1. Put a little air into the new inner tube (enough to give it shape but keep it soft)
2. Insert the valve into the hole in the rim first
3. Tuck the inner tube between the tire and the rim
4. Use your hands to push the tire bead back onto the rim (try to avoid using tire levers to prevent pinching the tube)
5. Before inflating, check all the way around the rim to confirm the inner tube is not pinched between the tire and rim

Step 6: Inflate and install

Inflate to the recommended pressure, reinstall the wheel onto the frame, and confirm the quick-release is tightened.

Patching a Tube (Emergency Method)

If you don’t want to replace the entire inner tube, you can use a patch kit:

1. Find the hole (inflate the tube and submerge it in water to look for bubbles, or hold it close to your ear to listen for the hiss)
2. Roughen the area around the hole with sandpaper
3. Apply rubber cement and wait until it’s slightly dry (becomes a bit tacky)
4. Apply the patch and press down firmly
5. Wait until the glue is fully dry before inflating

Skill 4: Brake Inspection and Basic Adjustment

Brakes are critical to your safety, so regular inspection is essential.

Inspection Items

1. Brake pad thickness: Rim brake pads have wear indicator lines; when worn to the line, they need replacing. Disc brake pads need replacing when thickness drops below 1mm.
2. Brake feel: When pulling the brake lever, you should feel significant braking force at about 1/2 of the lever travel. If you have to pull all the way to the bar before feeling anything, adjustment is needed.
3. Brake cables: Check for corrosion, fraying, or breakage.

Basic Adjustment (Rim Brakes)

Excessive brake lever travel:

1. Locate the cable adjuster barrel (usually near the brake lever)
2. Turn it counterclockwise to tighten the brake cable
3. Adjust in 1/4-turn increments and test the feel

Brake pad misalignment:

1. Loosen the brake pad fixing bolt with a hex wrench
2. Squeeze the brake so the pad contacts the rim
3. Adjust the pad position to ensure full contact with the rim braking surface
4. Tighten the bolt

Basic Disc Brake Inspection

Disc brake adjustment is more complex, so beginners are advised to mainly perform the following checks:

• Whether the brake pads have sufficient thickness
• Whether the rotor is warped (spin the wheel and observe if it rubs against the pads)
• Whether the brake fluid level is sufficient (hydraulic disc brakes)

If your disc brakes make unusual noises or braking power noticeably drops, it’s recommended to have a bike shop handle it.

Skill 5: Basic Derailleur Adjustment

Unsmooth shifting is the most common minor issue and can usually be resolved with simple adjustments.

Common Issue: Delayed Shifting or Skipping Gears

Cause: Usually a loose shift cable.

Adjustment Method:

1. Locate the barrel adjuster on the rear derailleur
2. If the chain has difficulty moving to a larger cog (slow upshift): turn the barrel adjuster counterclockwise, 1/4 turn at a time
3. If the chain has difficulty moving to a smaller cog (slow downshift): turn the barrel adjuster clockwise
4. Test ride after each small adjustment to confirm

Notes

• Don’t randomly adjust the limit screws (H and L). Incorrect adjustment can cause the chain to drop off or get caught in the spokes
• If basic adjustments can’t solve the problem, the shift cable may need replacing or the rear derailleur may need realignment. It’s recommended to take it to a bike shop.
