Regular Bikes Process

Step-by-Step Conventional Bike Diagnosis and Repair Process

1. Initial Rider Consultation

Before beginning any work, we consult with you to gather detailed information about the issues you're experiencing with your bike. Common problems include:

• Shifting issues or chain slipping
• Noisy, squeaky brakes
• Wobbling wheels or steering issues
• Difficulty pedaling or drivetrain resistance
• Tire flats or rapid air loss

This conversation helps us target specific areas for diagnostics and ensures we address the problems that matter most to you.

2. Comprehensive Visual Inspection

We start with a detailed visual inspection of your bike. This first step helps us identify any obvious signs of wear, damage, or potential failure points.

• Frame Inspection: We look for cracks, dents, or corrosion on the frame, especially in areas of high stress like the bottom bracket or head tube. Frame integrity is critical for both safety and performance.
• Brake and Gear Cables: We inspect all visible brake and gear cables for fraying, rust, or tension issues. Damaged cables can affect both shifting and braking reliability.
• Tire and Wheel Condition: We check your tires for punctures, excessive wear, or embedded debris, and inspect the wheels for true (ensuring they aren’t wobbling or out of alignment).
• Chain, Drivetrain, and Crankset: The chain and drivetrain are inspected for signs of rust, excessive wear, or damage. A worn-out drivetrain can result in poor shifting, slipping chains, or even drivetrain failure.

This thorough inspection gives us an overview of the bike’s condition and helps us identify areas that need further attention.

3. Brake System Diagnosis

A well-functioning brake system is crucial for your safety, and we carry out a detailed check of your bike’s brakes, whether you have rim brakes or disc brakes.

• Brake Pad Inspection: We check for wear on the brake pads (for rim or disc brakes). Worn-out pads significantly reduce stopping power, especially in wet conditions. We inspect them for uneven wear, contamination, or glazing, all of which affect braking efficiency.
• Brake Cable Tension and Leverage: For bikes with mechanical brakes (both rim and disc), we inspect the brake cable tension. Over time, brake cables can stretch, fray, or develop slack, leading to reduced braking response. Hydraulic brake systems are checked for any leaks or signs of pressure loss.
• Brake Lever and Caliper Alignment: We ensure the brake levers engage smoothly and with sufficient tension. For disc brakes, we ensure the calipers are aligned correctly to the rotors, avoiding any rubbing or noise.
• Rotor or Rim Condition: If you have disc brakes, we inspect the rotors for warping, cracking, or contamination. For rim brakes, we check the braking surface for wear and ensure that the pads are making even contact with the rim.

Once we diagnose the braking system, we perform adjustments or replacements as needed to restore safe, responsive braking.

4. Drivetrain and Shifting Diagnosis

The drivetrain is the core of your bike’s performance. Proper shifting and drivetrain function are crucial for smooth rides, and our comprehensive drivetrain diagnosis ensures every component is working correctly.

• Chain Wear and Lubrication: We check the chain for wear and proper lubrication. An overly worn chain can cause premature wear on the cassette and chainrings. Chain stretch is measured to determine whether replacement is necessary.
• Cassette and Chainring Inspection: We inspect the cassette and chainrings for wear and damage. Worn teeth can cause poor shifting and chain slippage, affecting your ride quality.
• Shifter and Derailleur Adjustment: Both the front and rear derailleurs are checked for proper alignment and operation. Misaligned derailleurs can lead to slow or inaccurate shifts. We fine-tune the derailleur settings to ensure smooth and precise gear changes.
• Cable Condition and Housing: Gear cables are inspected for wear, fraying, and corrosion, especially in the areas where they pass through housing. Frayed or stretched cables can cause sluggish or inconsistent shifting.

After diagnosing any drivetrain issues, we adjust, clean, or replace components as necessary to ensure smooth, precise shifting and efficient power transfer.

5. Wheel and Tire Condition

Wheels and tires are vital for a smooth ride, and issues here can lead to discomfort, poor performance, or even unsafe handling.

• Tire Pressure and Wear: We inspect the tires for wear, cracks, and punctures and ensure they’re properly inflated to the manufacturer’s recommended pressure. Underinflated or worn tires can increase rolling resistance and decrease overall ride comfort.
• Wheel Truing and Spoke Tension: We check for wheel alignment (truing) to ensure the wheels spin straight and without wobble. Misaligned wheels can cause poor handling and increased wear on other components. We also check spoke tension, adjusting as necessary to avoid loose or broken spokes.
• Hub Inspection and Adjustment: We check the wheel hubs for smoothness, ensuring there’s no resistance or grinding that could indicate worn bearings. Any roughness in the hub is addressed with bearing adjustments or replacements.

Wheel-related issues can affect both performance and safety, so we take great care in addressing any problems.

6. Pedal and Bottom Bracket Inspection

The pedals and bottom bracket are crucial components that directly affect your ability to transfer power to the bike efficiently.

• Pedal Inspection: We inspect the pedals for any play, cracks, or damage. Loose pedals or worn bearings can make pedaling inefficient and uncomfortable.
• Bottom Bracket Condition: The bottom bracket (the bearings where the crankset rotates) is checked for smoothness and noise. Any grinding, resistance, or looseness is a sign that the bottom bracket needs to be serviced or replaced.
• Crank Arm Tightness and Alignment: We ensure the crank arms are properly secured and aligned. Loose crank arms can lead to inefficient pedaling and even damage to the crankset.

We make any necessary adjustments or replacements to ensure your bike pedals efficiently and smoothly.

7. Steering and Headset Adjustment

Smooth and precise steering is essential for handling, especially during descents or at high speeds. We thoroughly inspect and adjust the steering components.

• Headset Bearing Check: The headset bearings allow for smooth rotation of the handlebars. We inspect for any roughness, grinding, or play in the bearings, which can affect steering precision. If the bearings are worn, we’ll service or replace them.
• Handlebar Alignment and Tightness: We ensure the handlebars are properly aligned and secured. Misalignment or loose handlebars can cause poor handling and pose a safety risk.

Once inspected, we adjust the headset and ensure your bike handles predictably and comfortably.

8. Suspension Check (for Bikes with Suspension Systems)

For bikes equipped with suspension systems (either front suspension forks or full suspension), we ensure the suspension is functioning optimally.

• Fork and Shock Inspection: We check the suspension fork and rear shock (if applicable) for signs of wear, leaks, or damage. Faulty suspension can affect handling, especially on rough terrain.
• Suspension Tune and Rebound Settings: We adjust the suspension settings (air pressure, damping, and rebound) to suit your weight and riding style, ensuring the suspension performs as intended.

After adjustments, we ensure the suspension system is responsive, smooth, and set up for your riding conditions.

9. Final Test Ride and Adjustment

Once all components have been inspected, repaired, or adjusted, we take your bike for a test ride. This step ensures that everything is functioning correctly in real-world conditions.

• Real-World Performance: We test shifting, braking, steering, and overall ride quality under normal riding conditions, checking for any remaining issues.
• Final Adjustments: After the test ride, we make any final tweaks to fine-tune the bike’s performance, ensuring everything works perfectly.

Only once we’re confident that your bike is performing optimally will we consider the service complete.
