For sale is the 4iiii precision 3 power meter. It is less than a year old and has had very limited use. It is a warranty replacement for the Shimano crank recall so doesn't come with its box, but as you can see from it's condition it's nearly new. There is one very small mark from being stored in my shed. It's 172.5mm. New bike with shorter cranks forces sale! These are great power meters. I have one on the other bike too and never had a problem.
