Patrick, Thanks for your interest. A bag like what you describe would start at about $180 in tan canvas with one large compartment. I have not done one for a compact frame yet so there would be a bit of back and forth tracing of your internal triangle shape and locating all of your braze ons etc. so that I know where to locate the straps. What size and year fargo is that? If I can find one locally to make a tracing from it would save some time.
Also, while I am thinking about how I would go about the design, confirm that you would give up both bottles inside the main triangle. One thing I try to avoid with my bags is going all the way to the bottom bracket and having possible interference with the front derailer. I try to keep the bottom of the bag close to level, and am envisioning a bag that would fill the space of the front triangle from the top of each upper bottle boss up to the top tube. My current lead time on a project like this would probably be 6-8 weeks at best. I am completely buried with my Rambler frame set project as it moves from production samples to production. Although, I like to make time for the bags as it is almost therapeutic to still be making something with my own hands, time is just at an incredible premium. I know you have worked with Ely in the past, and if he is not too swamped I am almost thinking of sharing this project with him. That would of course depend on him wanting the work and your timeline. He has the skills, and I could work through the detailing with him. Just thinking out loud through my finger tips. Think about it a bit, let me know, and I will work it into my schedule. -- Rob Perks oceanaircycles.com On Tue, May 22, 2012 at 9:48 AM, PATRICK MOORE <[email protected]> wrote: > Rob: could you design a bag for a very compact frame like the one in > the attached photo?
