Bike Chains at Halfords
If you’re a regular bike rider, then you must pay attention to the health of your bike chain. Over time your bike chain can start to stretch and potentially affect other parts of your drivetrain reducing bike performance.
Investing in a new chain will ensure your bike gears are in perfect shape and extend the bike's lifespan. Halfords stock a range of different width chains from top brands like Clarks, SRAM and Shimano.
Choosing a chain depends on your bike’s gears as your bike chain will have to match the number of gears you have in the drivetrain. We stock chains from 5-speed to 11-speed in black, grey and silver, as well as stocking single-speed bike chains.
If you’ve never replaced a bike chain before, read our step-by-step guide onhow to replace a bike chain and ensure your new chain is well maintained with our wide range ofbike lube.
Bike Chains FAQs
How to tighten a bike chain?
To tighten a bike chain, first locate the rear wheel axle nuts or chain tensioners. Loosen them slightly, pull the wheel back to remove excess slack, then tighten everything back into place. The chain should feel snug but still move freely without being overly tight.
How long should a bike chain last?
A bike chain typically lasts between 1,500 and 3,000 miles, depending on how often you ride and how well you maintain it. Regular cleaning and lubrication can help extend its lifespan and keep your drivetrain running smoothly.
How often to lube bike chain?
Most riders should lube their bike chain every 100–150 miles or whenever the chain starts sounding dry. If you ride frequently in wet, muddy, or dusty conditions, you may need to lubricate it more often to keep it performing at its best.
