This is my fifth go at forming a good curve in 10 mm bar for the front and rear carriers. Perhaps I should put in photographs of the failed attempts. One must have standards and, of course, you can enjoy failures of your own.
One curve was used on the front forks for pannier carriers while the other two are here in the rear. They will support boxes in the middle and on the left hand side and a stool on the right.
