Why Your Bike Is Making a Clicking Noise (and How to Fix It): The Complete Step-by-Step Diagnostic Guide

A clicking bike is annoying, and it can also be a warning. The good news is that most clicks come from a short list of places, and you can find them by checking one thing at a time.

Step 1: Find when it clicks

Does it click once per pedal turn, once per wheel turn, only when you stand, or only on bumps? Once per pedal turn points to the cranks, pedals, or bottom bracket. Once per wheel turn points to the wheel, tyre, or brake. Only on bumps points to a loose bolt, bottle cage, or accessory.

Step 2: Check the simple things first

Tighten the quick releases and thru-axles correctly, check the pedals, saddle clamp, seatpost, stem, and bottle cage bolts, and look for a loose mudguard or cable touching the tyre. Many clicks disappear here.

Step 3: Check the drivetrain

Clean the chain, check for a stiff link, and look at the chainring bolts and derailleur. A stiff link clicks once per chain pass, while loose chainring bolts click with each pedal stroke.

Step 4: Check wheels and brakes

Spin each wheel and listen. Check for a spoke that feels looser than its neighbours, a brake pad touching the rim or disc, and a tyre with something stuck in it. If the click stays after these checks, have a mechanic check the bottom bracket and headset.

Q: Is a clicking bike safe to ride?

A: Most clicks are harmless, but a click with play in the cranks, wheels, or headset is not. If anything feels loose, stop and check it before riding far.
