Anyhow, I don't have the beautiful 29er I'd like just yet, and with a baby on the way, it doesn't look like it's in the budget anytime soon. But I'm still doing trips on the road bikes and wanted to make a frame bag in the bikepacking style to pare my system down to a rackless setup. Hopefully I can manage to loose the backpack as well (except maybe as an overflow).
Copy and paste from the other forum I posted on because I am lazy:
I've been wanting to make one of these for a while now. Finally got the guts to order the fabric and give it a shot over the winter break. It all went pretty well except for one minor major detail. I was so afraid of making it too small, I ended up making it too big. So it looks a little sloppy in the frame, but functionality is pretty darn good right now.
An over all shot of the bag. I just loosely filled it with some clothes to give it form. As you can tell, it's a tad large for the space.
And here is a detail shot of the top flap. Just a length of hook and loop, but I made the flaps, as well as the spine of the bag where it contacts the frame, with a microfiber liner to both treat the paint a little nicer and to add a layer of abrasion for the bag itself.
And finally, a detail shot of the zipper. I added a little storm flap for added weather resistance. The bag is made with a PU coated fabric, and I plan on finishing it off with some seam sealer, so all in all, it should handle a decent rain or driving mist, but definitely won't be fully waterproof.
So while I'm a little bugged that my paranoia resulted in a slightly larger bag, it seems to do well stuffed with some clothes. I threw it on a bike and pedalled a bit. Maybe some slight leg rub, but nothing major. My tent poles fit just inside the top, and my tent fits in my seat bag (old fashioned canvas seat bag, not a full sized bikepacking model). I was considering making a full handlebar bag for the sleep system, but after looking at some other threads here, a sling makes the most sense and will be pretty versatile. I was worried about making one set size and then my winter bag being larger than my summer bag.
