Different Type of Bikebag

[mtnbound]

I have a question to throw out to everyone.  I have a stumpjumper fsr and I am planning on using it for the CTR. The frame area is miniscule, particularly since I think I am going to have 2 water bottles (one in the frame and the second below the frame) to keep as much water off my back.  This means no frame bag will work.

So,  I am thinking of making a bag to fit in the area underneath the front of the seat down to the top of the frame, attaching to the bottom of the seat, the seat post and the frame.  It would be about 4-5 inches wide and about 12-14 inches long.  I have seen various bikepacking pics on this site and others and have never seen anyone try putting a bag in this area.  Is there a reason for this? Will a bag in this spot make it too hard to pedal/ dismount/carry?

Are talking about doing something like what Lynda had for the AZT 300 from Revelate?

three reasons I can think of:
the zipper will be near vertical so things would want to fall out, maybe not a big deal

when I carry my bike, I put the seat nose over my shoulder.  can't do that with that bag.

The bag shape will be specific to your frame AND seat height.

If you can get over or around these issues, it should work great.

bart - thanks for the link!  Yes, that is exactly what I am referring to.  Nice to know that it seems to have worked for lynda. I also liked how she was able to use that small upper portion of the triangle to carry extra stuff (she strapped in 2 tubes w/gorilla tape); otherwise that area is wasted frame space.  My bike just doesn't have much room for bike bags so I have to take what I can get.

jeremy11 - thanks for the response.  I am concerned about carrying the bike with it.  Maybe if the bag can easily be detached from the seat and frame and let it swing sideways on the seatpost, it might be doable to carry.  Have to see if that is a possiblity.  I am not sure how much carrying is needed on the CTR, but I figure there is enough that I have to fully prepared.  I am not too concerned about stuff falling out; it will be a small pain but w/o such a bag, I will have to get a bigger backpack and carry the extra weight on my back.  I know the bag will have to be custom fit but I am going to try to do it (if the carrying issue will work out).

i made this bag for an FSR a few years ago. they (frame and bag) are on to a second owner and still in use. it's medium frame and a 70 oz bladder can fit in there. it was a challenge to build, but can be done. take the challenge walter, you can do it!
