5 Telltale Signs Your Bike Needs a Professional Service (Before It Breaks)

Long before something breaks, your bike usually tells you. A faint click on a climb. A gear that hesitates. A brake lever that comes a little closer to the bar each week.

Catch those signs early and the fix is often a quick adjustment. Here are the five to watch for, what each one usually means, and when to book a service.

The Five Signs at a Glance

1. Creaks, Clicks and Grinding

A well-tuned bike runs quietly. When it starts making noise, treat it as a warning, not background sound.

• Clicking When You Pedal: Often the bottom bracket, chainring bolts, pedals or the rear hub.
• Ticking When You Coast: Often the rear hub.
• Creaking at the Front When You Stand: Often the headset, or the stem and handlebar clamps.

Noises are hard to trace on your own, because sound travels through the frame. A mechanic can work through the likely spots in order.

2. Hesitant or Skipping Gears

A gear change should be quick and clean. If the chain hesitates, rattles or jumps between cogs on its own, the usual causes are cable tension, dirt inside the cable housing, or a derailleur hanger that has been knocked out of line. A bent hanger cannot be fixed with the barrel adjuster; it needs straightening with the right tool.

3. Soft, Noisy or Weak Brakes

Brakes are the most important safety part of your bike, so any change deserves attention before you ride again.

A simple check from the ABC Quick Check: when you pull a brake lever, it should stop short of reaching the handlebar.

If your brakes feel different, get them checked before your next ride.

4. The Chain Slips Under Power

If the chain skips when you stand up to sprint or climb, your drivetrain is probably worn. Chains get longer as they wear. Sheldon Brown's guide is to replace the chain when 12 inches of it measures 1/16 inch long; leave it to 1/8 inch and your most-used sprockets will be badly worn, and a new chain may skip on them. Catching it early means buying a chain rather than a chain, cassette and chainrings.

5. Play or Roughness in Bearings

Your bike turns on bearings in the hubs, bottom bracket, headset and pedals. They should turn smoothly with no side-to-side play. Three quick checks:

• Headset: Hold the front brake on and rock the bike back and forth. A knock means the headset is loose.
• Wheels: Hold the top of each tyre and try to move it side to side. Any play points to the hub bearings.
• Cranks: Push and pull each crank arm sideways. A clunk points to the bottom bracket.
