Your triangle. Your bag.
Off-the-shelf frame bags rarely fit — too short at the top tube, too wide at the bottom bracket, zipper on the wrong side. Sewing your own gets you a bag made for your frame, not a size chart: 50–80 € in materials, 3–5 hours for the first build, and any household machine that handles Cordura will do. The one tip that matters: sew a divider between the side walls so a loaded bag can't bulge into the crank — and always check clearance with a full bag over a full crank turn.
The first one is rarely perfect. That's normal — seams can be unpicked, and the second build is faster.
