Will a Shimano Dura-Ace 54T 4-bolt fit a Ultegra 4-bot crankset?

 

I am looking for a 54T / 55T / 56T chain ring for my TT bike but ULTEGRA 11 spd seems limited at max of a 53T.

For example

(55T) 1pc Shimano Dura-Ace FC-R9100 110mm BCD 4Arm Outer Chainring - will this fit latest Altegra 11 spd crankset?

Hope someone can help

As I understand it, Shimano R9100, Ultegra R8000 and 105 R7000 chainrings are interchangable.

You cannot go back a series IIRC (and stand to be corrected) i.e. R9000 chainrings do not fit R9100 DA Cranksand vice versa and Ultegra R6800 chainrings do not fit 9100, 800 and 7000 series cranks.

 

Correction, from Absolute Black website:

In short EVERY Shimano 4 bolt crank. Shimano Dura-Ace 9100, R9120, R9150 & R9170 Di2 & all 9000 series, Ultegra 8000, R8020, R8050 & 8070 Di2 & 6800, 105- R7000, R7020, R7070, 5800, 4700. Di2 compatible. 10 / 11 / 12spd compatible. Use bolt covers for best appearance.

So I have the Ultegra 52T Chainring, as per picture

 

So I should be then able to go the Dura-Ace as per attached picture, right, if I read the thread correct

Yes you should and it should fit BUT

The shaping of the arms of the Dura Ace may not perfectly match that of the Ultegra. They pop out of the same forging mould but the Dura Ace under goes more post machining to reduce weight. The rings may not fit very well aesthetically but mechanically they will work as the mounting pattern is the same

Excellent.... Thanks you, well looks may be one thing, but function is power and thats where I need to go...

 

No to find them is another question LOL

 

cheers, appreciate it
