Can you replace chainrings?

Once you’ve removed the bolts and put them to one side, remove the chainrings for cleaning or replace them with new ones. You can tell if a chainring needs replacing by the profile of the teeth – if they are pointed like shark’s fins, it needs replacing.

Do I need to change chain if I change 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.

How do narrow wide chainrings work?

The sole purpose of the narrow wide chainring is chain retention. The narrow wide tooth pattern keeps the chain from moving left to right and eventually popping off the chainring while riding. No one likes to drop their chain on the trail, especially in a race scenario where every second counts!

How do you know when your chainring is worn out?

“An inner chainring is considered worn when a clean new chain starts to chain suck [when doesn’t release well at the bottom of the chainring) and an outer chairing is considered worn when it is very rough running or the shifting is poor or inconsistent.

Can you change chainrings without removing crank?

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.

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.

Where do you put the branding on a chainring?

The inner ring will usually have a small tab on the inside of the outer part of the ring, which also needs to be fitted behind the crank. The ramped edge of the teeth – which aids shifting – or any branding or other markings should be visible as you place the ring on. With rings aligned, place each nut into the bolt hole.

What kind of wrench do I need to change chainrings?

Some high-end cranksets allow you to remove the chainring bolts with only a hex or torx key, but if your chainset uses traditional bolts, you’ll need either a chainring nut wrench tool to sit in the slotted recess of the chainring nut or another hex key (often 1mm larger than the front) to hold in the rear nut and prevent it turning.
