1. Myth: You Only Need to Pump Your Tyres When They Look Flat

Truth: Tyres Should Be Checked Regularly, Even If They Look Fine

Many cyclists assume that if their tyres aren’t visibly deflated, they’re good to go. However, tyre pressure gradually decreases over time, even without visible signs. Under-inflated tyres can increase rolling resistance, reduce control, and lead to punctures.

How Often Should You Check?

• Road bikes: Every 2-3 days 70-90psi

• Mountain bikes: Once a week 25-34psi

• Hybrid/commuter bikes: Weekly 60-80psi

2. Myth: A Squeaky Chain Just Needs More Lubrication

Truth: A Dirty Chain Needs Cleaning Before Lubrication

While lubrication is essential for chain health, applying oil to a dirty chain can trap grime and accelerate wear. A proper cleaning routine, followed by appropriate lubrication, extends the life of your drivetrain. I would recommed using a wax based lube like Smooth lube.

Proper Chain Care Steps:

1. Wipe down the chain after every few rides.

2. Clean it with a degreaser every few weeks.

3. Apply the right amount of lube (not too much) and wipe off the excess.

3. Myth: If Your Brakes Squeak, You Should Replace Them Immediately

Truth: Squeaky Brakes Often Just Need Cleaning or Adjustments

Squeaky brakes don’t always mean they’re worn out. In many cases, dirt, debris, or misalignment causes the noise. Before replacing them, try cleaning the brake pads and realigning them for even contact.

Fixing Squeaky Brakes:

• Wipe down the brake rotors with brake cleaner .

• Sand the surface lightly if they’re glazed.

• Replace brake pads

• Check for misalignment and adjust accordingly.

Myth: You Only Need to Service Your Bike When Something Feels Wrong

Truth: Preventative Maintenance Saves Money and Prevents Breakdowns

Waiting until you hear a strange noise or feel resistance before servicing your bike can lead to bigger (and more expensive) problems. Routine maintenance helps identify minor issues before they turn into costly repairs.

Recommended Service Intervals:

• Basic tune-up: Every 3-6 months

• Full service: Annually

• Chain replacement: Every 2,000-3,000 km (depending on riding conditions)Unusual noises (eg. creaking or grinding).

Myth: All Bike Repairs Can Be Done at Home with a Few Tools

Truth: Some Repairs Require Professional Expertise

While basic maintenance like cleaning, lubrication, and minor adjustments can be done at home, certain repairs—like bottom bracket servicing, wheel truing, and hydraulic brake bleeding—require specialised tools and expertise.

When to Visit a Professional Mechanic:

• Persistent gear shifting issues

• Unusual noises from the bottom bracket

• Hydraulic brake servicing

• Wheel truing and spoke tension adjustments

• Cracked carbon or frame repairs
