I'm fascinated that the owner of this Birdy found it necessary/useful to upgrade the stock 160 mm front rotor to a 180 mm, at least that's what it looks like. 160 mm is already huge for such small wheels, when there are people who are happy with 140 mm rotors on full size roadbike wheels. And it has no racks for touring. This person has some serious stopping needs. Possibly likes to ride up mountains and race down them again. Of course you can never have too much stopping power, as long as you know how to use it safely. (No criticism from me, just... mind boggling.)
