...why I wanted the photo, I explained that the rack is inaccessible to a lot of different cycle designs. They said it worked for them. I congratulated them, non-sarcastically or PA, on it working for them and took my photos.
As we were talking, I talked about the problems the racks create for me and other cyclists riding different designs and it then came out that the rack only works for them if they can get in there before others have or can get on the end.
