Designing a frame means having to manage an incredible one quantity of trivial trifles of capital importance.
You have to go through it to believe it .. whole evenings discussing compatibility with new groups, bikepacking systems, accessories and options of all kinds. In the end, choices have to be made and therefore something must be eliminated in favor of something else but I never thought I'd spend three days just checking spaces and dimensions related to the millimeter positions of the bottle cages according to the dimensions of the triangles dictated by the various measures and allow for each bottle cages that normally have 2 screws to have 3 thus allowing a double position (high or low) to make the most of the space depending on the type of bag and bottle used. As you have certainly already deduced from a quick glance at the CAD print attached here, we have chosen to provide 3 bottle holder holes for each of the 3 bottle positions provided (down tube above, seat tube, down tube below).
Here too there are not many frames with this '3X3' solution. Thanks to the side entry bottle cages, a small frame can carry 2 large 750 mm bottles in the triangle, as well as still having space for another bottle under the seat tube capable of holding up to a liter and a half (!), Which is not really banal for such a small frame. The Scotsman locomotive used by Stefano Romualdi photographed at the arrival of the South Tyrol Trail and visible right above this text is a Small size and as you can see it carries two large 750 ml water bottles perfectly aligned in the triangle.
