I have a 2021 Madone SLR7. I currently have the original Bontrager tires with over 4k miles on them. It might be getting close to time to change them.
They are 28's by Bontrager, the R3.
It seems they don't make a 30mm.

I'm thinking of putting on 30mm Conti 5000's.
I am 60, I ride because I enjoy it, I have never raced and never will.
Any drawback to putting on the 30's?

Thanks
