Unless you have 110 bcd on your 53/39, will 50/34 rings even fit the cranks?
The new Shimano cranks use a 4 arm design with the same BCD so all the rings for the 5800, 6800, and 9000 cranks are all the same BCD regardless or compact or not.
So yes, they will work. Thanks
Ah, good to know, thanks!
Ah too bad they're not 52/36 otherwise I'd consider this. Bumping...

I've got a 50/34 set with about 50 miles on them. I'd be happy to swap. PM me if you are still looking.
