Our verdict

Overall

out of 100, average of 7 categories

A conventional, well-specified tri bike from a major brand: clean internal cabling, Di2 on every build and deep Vision wheels on the upper models. It offers no integrated hydration or storage and only four sizes, and the design dates from 2020.
