Frame bag template
To make a perfect fitting frame bag it is crucial for me to have the exact dimensions of your frame. My preferred method is tracing a scaled picture of your bike in CAD. This picture requires some care to avoid issues like lens distortion or improper scaling, ideally the picture is taken with a dedicated camera but most modern phones will be good enough.
This is an example of a perfect picture, below are the 4 things you need to get right:
- A reference dimension taped to the top tube, preferably a ruler or a tape measure but an A4 will do as well.
- If you want a bolt-on bag remove your bottle cages and put the bolts halfway back into the frame. On a half frame bag put the biggest bottle you want to be able to use with the bag in your cages.
- Take the picture crouched down so the chainstays, seatstays and fork appear as one, it is crucial the lens is level and pointed at the center of the frame.
- Take the picture from at least 5 meters away, a good indication is both wheels fitting in the frame with room to spare. Don’t worry about zooming in, resolution is rarely an issue but lens distortion very much so.
