Disc Rotor upgrade

gnave

Hey all,

My bike has Shimano Ulegra 6700 DI2 Group set with Shimano BR-RS805 disk brakes callipers. The bike was originally delivered with rotors SM-RT99 https://bike.shimano.com/en-EU/product/component/saint-m820/SM-RT99.html

Can I replace them with the newer version? SM-RT800 https://bike.shimano.com/en-EU/product/component/ultegra-r8000/SM-RT800.html

Thanks for any input

Yes - just make sure you get the same size. Not sure that you'd notice much benefit tho - unless the old ones are just worn out?

TBH it's pure: I like the look of the new one more.

Will the dura ace model work too? https://bike.shimano.com/en-EU/product/component/duraace-r9100/SM-RT900.html

Yes but cheaper to use magic marker on the fins of the otherwise identical Ultegra ones.

DA are 8gms (140mm) or 10gms (160mm) lighter than Ultegra to be strictly accurate so not identical - although functionally they will be.

Is the Dura Ace logo lighter?
