Andrew at Bedrock Bags made this frame bag for my pre-production Salsa Bucksaw. I just used it for 12 days in Iceland and it was simply perfect. Andrew's bags are really great. I can't say enough good things about them. I sent him a couple templates to best show the dimensions as well as a handful of photos with those templates in place. With the funky bottom bracket area complete with dropper post lines and everything else, he nailed it.
