This bag is very well
This bag is very well made but was a little bit big for my 54cm 2022 Trek Emonda. I was unable to fit a 21oz insulated Bivo bottle in the lower bottle cage but was able to squeeze in a 21oz uninsulated Bivo bottle beneath it, although it was pushed up against the bottom of the bag.
I wish the zipper pulls were able to tuck into their protective "pocket" a little bit more. They sort of dangle into the airflow, which is not ideal if you are trying to optimize the aero of the system.
