I'd quite like to swap out the 50 tooth ring with a 46 tooth one - is there a compatible one?
6800 or any compatible 110mm 4-bolt asymmetric chain ring will fit, but you will need new nuts and bolts

Thanks, and thank @umop3pisdn for the cheaper option.
How come new nuts/bolts are necessary?
Will be interesting to see how 46-34, rather than the more normal (I think), 46-36 works.

I have a Tiagra 4700 Chainset and I'd quite like to swap out the 50 tooth ring with a 46 tooth one - is there a compatible one? I'm confusing myself with arm/bolt numbers.
