What I want is something like a little saddle pack but I don’t want it under my saddle. So something I can strap to say the downtube behind the bottle cage. Frame straps are popular, which is close to what I want, but it needs to hold tube, possibly tubeless kit, maybe CO2, and a multi tool.
I don’t really want my tool getting regularly covered in mud, and that’s quite a few things to carry together. So I could wrap them all in some sort of tiny little drybag, but is there something that’s integrated? Needs to be slim to avoid being clipped by pedals if it’s on the downtube.
On the Salsa I have two bottle cages so I could easily put a cannister in one, but that means only one bottle which isn’t enough for longer rides for me. And my XC bike only has one cage anyway.
