Mountain Bike Chain FAQ

What is the average lifespan of a mountain bike chain?

On average, a well-maintained mountain bike chain should last between 750 to 1300 miles, depending on riding conditions and maintenance habits. These are the rough timelines that we use, tracked with our GPS computers - but the condition of the change after mileage really does depend on the riding conditions and also the maintenance and care the chain has been shown.

How do I know when my mountain bike chain needs to be replaced?

Look out for poor gear changes, excessive stretching (measure with a chain wear tool), rust, or visible damage to determine if your chain needs replacing. These are the most important factors we think determine when to know a chain needs replacing.

Can I use a road bike chain on my mountain bike?

It is not recommended to interchangeably use chains because mountain bike chains are designed to handle more dynamic stress and different gear ratios. Mountain bikes and road bikes are incredibly different machines, so place different stresses on different components.

How do I clean my mountain bike chain?

Use a quality degreaser and a chain brush to scrub the chain. Rinse thoroughly and apply a suitable chain lubricant after drying for the best results and performance.

What is the best lubricant for a mountain bike chain?

Select wet lubes for muddy, wet conditions and dry lubes for dusty conditions. This is a pretty good rule to stick by, understandably in the UK - we sell more wet chain lube.

Can I repair a broken mountain bike chain on the trail?

Yes, with a chain tool and a quick link or spare chain pin, you can temporarily fix a broken chain until you get back for a proper repair.

How do I adjust chain tension on a mountain bike?

On bikes with derailleur systems, the rear derailleur takes care of tension. On single-speeds, you'll adjust tension by moving the rear wheel within the dropout.

Does a worn chain affect other bicycle components?

Yes, a worn chain can accelerate wear on chainrings and cassettes, making it vital to replace your chain at regular intervals to protect both performance and your budget on replacing other components.

What do different chain speeds (e.g., 10-speed, 12-speed) mean?

The term refers to the number of gears on your cassette. It's crucial to match the chain to the drivetrain's speed for the best performance.

How often should I lubricate my mountain bike chain?

This depends on ride conditions, but generally, lube your chain every 100-150 miles or after riding in wet or very dirty conditions.

What are some recommended brands for mountain bike chains?

Shimano, SRAM, and KMC are some of the most reputable brands for mountain bike chains known for their reliability and performance.

Can I shorten a new mountain bike chain if it's too long?

Absolutely. Chains often come longer than needed and can be shortened with a chain tool for the correct fit.
