Are Shimano chainrings interchangeable?

Thus, cranks from Shimano, SRAM, and Campagnolo are freely interchangeable along with those from all aftermarket brands (e.g. FSA, Rotor, Praxis, etc.). And while it is preferable to match the chainrings/crankset to the transmission, there is no strict need to do so.

Are Ultegra chainrings interchangeable?

Are 6800 and R8000 chainrings compatible?

Anyone know if 6800 chainrings are compatible with r8000 cranks. Would you need to adjust the FD? The official answer from Shimano is “Nope!”. The fact that the two have slightly different chainlines (*very slightly) probably matters quite a bit in this case.

Are 6800 and 8000 chainrings interchangeable?

Worthy of note: the new R8000 components are all cross-compatible with the previous 6800 generation and just about any other Shimano 11-speed mechanical groupset. This means that if you’re on a recent 11-speed Shimano road groupset, you can mix and match many of the components reviewed here.

How long should chainrings 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 often should you replace chainrings?

In theory, a clean chainring/chain/cassette that sees no road grit and is lubricated constantly should last virtually indefinitely (for most intents and purposes). Also, changing your chain on time will save you many cassettes as well as chainrings. Just keep an eye on the chain’s wear and replace it when needed.
