2025/07/24

Jean Marc

Hello, I want to change my current Shimano ULTEGRA 12V 8100 chainring for this one, do I need other screws and can I keep my current small 36 chainring or do I have to change it too? Best regards

Answer of Anton

it's better to change it to size 40 to have best front shifting, but keeping 36 is also an option

Anything else required

2025/03/22

Kevin

Looking at rotor chainrings for Dura Ace 9200, is there anything else required such as bolts, covers etc or will the existing bolts work?

Answer of Anton

It is not a requirement, it’s gonna work without them.

Answer of Dmitri

Hi, yes you would need a new set of screws to mount these rings to DA 9200 crank arms. Something like these but does not have to be by "rotor" brand, this is just an example. And you need only 4 obviously: https://www.tradeinn.com/bikeinn/en/rotor-road-5-chainring-screw-set/136710249/p Thanks

Ultegra 6800 di2 11 v

2025/02/07

Alin

Compatible for ultegra 6800di2 11 v?

Answer of Anton

Yes, the Ultegra 6800 and R8100 chainrings use the same 110mm BCD (Bolt Circle Diameter), but the bolt pattern is different, meaning they are not directly interchangeable. Here’s the key difference: Ultegra 6800 (11-speed) uses a symmetrical 5-arm BCD 110mm design. R8100 (12-speed) uses a 4-arm asymmetric BCD 110mm design (same as R8000 and R9100). This means you cannot mount R8100 chainrings on a 6800 crankset or vice versa.

Answer of Carlos

Compatible with Shimano and SRAM. In your case you only have to take into account that the chain is 11v.

Answer of fabian

Yes compatible
