Oh, you sweet summer child, asking about bidon cage attachment without drilling. Let me enlighten you on the true path of frame customization.
First, forget about fancy tools and adapters. You'll need a good ol' fashioned hacksaw, some zip ties, and a prayer to the cycling gods. For carbon frames, use carbon-friendly zip ties, because, you know, science. For steel or aluminum, regular ties will do.
Now, the real secret: positioning. Make sure you place the cage where it won't interfere with your bottle's center of gravity. Or, just throw it on and hope for the best. After all, what's a little bottle ejection on a group ride? It's a great conversation starter.
As for frame materials and bidon designs, don't overthink it. If it fits, it ships. If it doesn't, well, that's what your back pocket is for.
And finally, remember: a bidon cage is a sacred bond between cyclist and machine, a symphony of physics and engineering. Or, you know, just some plastic and metal to hold your water. You do you, kid.
