FAQ: How To Change Bicycle Chain Ring?

Can I change my chain ring?

Changing rings is not that difficult, and in some cases, it’s possible to replace chainrings without removing the crank. That possibility is limited by what ring sizes you’re using, but hey, it’s always nice when you can work smarter not harder. This trick works for most road cranks and some mountain cranks.

Do I need to change chain when changing chainring?

You can only change the chain in 2 tooth increments and almost always you can change a ring by 2 teeth and not need to change the chain length. Of course you should always check.

When should I replace my bike chain ring?

To keep these parts working well, you need to replace your chain before it becomes extremely worn. My rule of thumb is to replace it at 75 per cent wear (as measured with a chain-wear indicator). If you stick with this guideline, your cassette and chainrings will last a lot longer.

How do I know if my bike chain is worn out?

If the chain starts to lift off the top and/or the bottom of where it sits on the chainring teeth, this means that the chain is starting to wear or is worn. If your chain lifts off the ring like this, it’s likely worn.

Do cranksets come with bottom brackets?

BMX cranksets are generally sold separately to the bottom bracket (BB) and chainrings, rather than as a single-unit ‘chainset’. They consist of the crank arms, axle (spindle) and any necessary bolts and spacers.

How many miles should a chainring last?

A steady rider who stays on the big ring, keeps the drivetrain clean and doesn’t let the chain get too long before replacing it, and started with good quality components can get 60,000+ miles out of a chain ring.

How many miles should a cassette last?

Cassette lifespan can range between 4000 to 10000 miles, and this is affected by the cassette itself and maintenance frequency.

Can I put a road crankset on a mountain bike?

Not necessarily, You can use road on a mtb bottom bracket as long as the crank interface matches, and the spindle length is correct. If you’re looking to build a 2×9 or 1×9 mtn bike and have a nice set of road cranks handy, along with a serviceable BB, no reason not to go that route.
