With a busy engineering day job and a growing family, this is the best option for me. I've made a few tweaks to the production process that make sewing faster, easier, and more professional looking. The bag has a spot to tie a short cord from the bottom of the bag to the lower strap. This keeps softer cargo from creeping down and squishing through the gap (cord is currently not provided with the bag).
Also, I designed a new and improved hose clamp mount, and had my favorite local machine shop CNC them. There are three tapped M5.08 holes that the bag (or bottle cage) mounts to and cutouts that fit the body of a hose clamp inside them. This tucks the bulky body of the clamp out of the way and makes installation a breeze and there's one less thing to scratch your leg on. The new CNC mount will be $20 per mount including 3 stainless steel hose clamps.
The Everything Bag with new CNC mount (or fork with threaded holes) is a very robust and versatile way to carry gear on your fork (or downtube or other creative places on unusual bikes!). Treat it like an oversized water bottle holder or a lightweight low-rider front rack.
I have a few sets of bags and CNC mounts in inventory now, contact me at firstname.lastname@example.org to order (before the new website is operational).
