2. Safety Instructions

• Always wear a helmet that meets safety standards.
• Ensure all bolts and quick releases are securely tightened before each ride.
• Check tire pressure before each ride.
• Familiarize yourself with the brakes and gear shifters before riding in traffic.
• Obey all local traffic laws and regulations.
• Ride defensively and be aware of your surroundings.
• Do not ride at night without proper lighting (front white light, rear red light) and reflectors.
• Avoid riding in adverse weather conditions if you are not experienced.
• Do not perform stunts or aggressive riding that could damage the bike or cause injury.

3. Package Contents

Your OUSHIJIE GTR 3.0 Road Bike package should include the following:

• Bicycle Frame (partially assembled)
• Front Wheel
• Handlebar Assembly
• Seat Post and Saddle
• Pedals (left and right)
• Small parts box (reflectors, bell, owner's manual, basic tools)

Inspect all components for any damage during shipping. If anything is missing or damaged, contact your retailer immediately.

4. Setup and Assembly

Assembly typically requires basic tools (often included) such as Allen wrenches and an open-end wrench. If you are unsure about any step, it is recommended to seek assistance from a professional bicycle mechanic.

4.1. Install the Handlebar

1. Loosen the bolts on the stem faceplate.
2. Position the handlebar in the stem, ensuring it is centered and the brake levers are at a comfortable angle.
3. Tighten the stem faceplate bolts evenly, alternating between them, until secure.

4.2. Install the Front Wheel

1. Ensure the quick-release skewer is properly assembled and inserted through the front wheel hub.
2. Insert the front wheel into the fork dropouts, making sure the disc rotor (if applicable) aligns with the brake caliper.
3. Close the quick-release lever firmly. Ensure the wheel is centered and spins freely without rubbing.

4.3. Install the Seat Post and Saddle

1. Insert the seat post into the frame's seat tube. Ensure it is inserted past the minimum insertion line marked on the post.
2. Adjust the saddle height to a comfortable riding position (your leg should be slightly bent at the knee when the pedal is at its lowest point).
3. Tighten the seat post clamp securely.

4.4. Install the Pedals

• Identify the left (L) and right (R) pedals.
• The right pedal (R) threads clockwise into the right crank arm.
• The left pedal (L) threads counter-clockwise into the left crank arm.
• Apply a small amount of grease to the pedal threads before installation.
• Tighten pedals firmly with a pedal wrench.

4.5. Brake and Gear Adjustment

Your bike features internal cable routing for a cleaner look and protection. Ensure cables are not pinched during assembly.

This image highlights the internal cable routing design for a sleek appearance and the quality paint finish of the high-carbon steel frame.

Brakes and gears are typically pre-adjusted but may require fine-tuning after assembly and initial rides. If you are unfamiliar with these adjustments, consult a professional mechanic.

5. Operating Instructions

5.1. Shifting Gears

Your OUSHIJIE GTR 3.0 Road Bike is equipped with a variable speed drivetrain (available in 21, 24, 27, or 30 speeds). Use the shifters on the handlebars to change gears.

Figure 3: Road Bike Handlebars and Controls

This image shows the drop handlebars with integrated brake and shift levers, designed for responsive and sensitive braking.

• Rear Derailleur (Right Shifter): Controls the gears on the rear wheel (cassette). Use for fine-tuning speed and cadence. Shift to smaller cogs for higher speeds, larger cogs for easier pedaling uphill.
• Front Derailleur (Left Shifter): Controls the chainrings on the crankset. Use for larger changes in gearing, typically for significant changes in terrain (e.g., flat to steep climb).
• Shift gears smoothly by pedaling lightly while shifting. Avoid shifting under heavy load.

This image displays the 10-speed cassette, providing a smooth and efficient gear-shifting experience.

5.2. Braking

Your bike is equipped with mechanical disc brakes for reliable stopping power.

• The right brake lever typically controls the rear brake.
• The left brake lever typically controls the front brake.
• Apply both brakes simultaneously for effective stopping.
• Use the front brake with caution, especially at high speeds or on loose surfaces, as it can cause the front wheel to lock up and lead to a fall.
• Practice braking in a safe, open area to get a feel for the bike's stopping characteristics.

6. Maintenance

Regular maintenance will ensure your bike remains safe and performs optimally.

6.1. Cleaning

• Clean your bike regularly with mild soap and water. Avoid high-pressure washers directly on bearings.
• Dry the bike thoroughly after washing to prevent rust.

6.2. Lubrication

• Lubricate the chain regularly (every 100-200 km or after riding in wet conditions) with bicycle-specific chain lubricant.
• Apply a small amount of lubricant to pivot points on derailleurs and brake levers.

6.3. Tire Pressure

• Check tire pressure before each ride. The recommended pressure range is usually printed on the tire sidewall.
• Proper tire pressure improves ride quality, reduces rolling resistance, and prevents pinch flats.

6.4. Bolt Check

• Periodically check all bolts (stem, seat post, crank arms, brake calipers, etc.) for tightness.
• Do not overtighten bolts, as this can strip threads or damage components.

6.5. Brake Pad Wear

• Inspect brake pads for wear. Replace them when they are worn down to the wear indicators or if braking performance degrades.

7. Troubleshooting

7.1. Gears Not Shifting Smoothly

• Cause: Cable stretch, dirty cables, bent derailleur hanger, or improper limit screw adjustment.
• Solution: Check cable tension and adjust if necessary. Clean and lubricate cables. Inspect derailleur hanger for alignment. Consult a mechanic for limit screw adjustments.

7.2. Brakes Squealing or Rubbing

• Cause: Contaminated brake pads/rotors, misaligned caliper, or bent rotor.
• Solution: Clean rotors with isopropyl alcohol. Realign brake caliper. If rotor is bent, it may need truing or replacement by a professional.

7.3. Chain Skipping

• Cause: Worn chain/cassette, improper gear adjustment, or stiff chain links.
• Solution: Lubricate chain. Check gear adjustments. If chain or cassette are worn, they may need replacement.

7.4. Flat Tire

• Cause: Puncture, pinch flat, or valve issue.
• Solution: Locate the puncture, patch or replace the inner tube. Ensure tire is free of debris before re-inflating. Maintain proper tire pressure to prevent pinch flats.

• Regularly check tire pressure for optimal performance and to prevent flats.
• For smoother gear changes, ease off pedaling pressure slightly when shifting.
