1. places that can be cleaned up:
-front drop out, hanger, stay area. its pretty good, but it does not lend itself to quick tire change short of the zip strap hack. connection here would have to be a part of the transportability solution.
-bottom bracket stay boom connection area. it is pretty good, but it does have some issues with alignment, and i beleive this connection could be a critical element of the transportability solution.
-steer tube to boom connection i like the simplicity of it, but this would also be a critical point of the transportable solution.
- seat
-leading edge of seat to rear drop out area
i think the transportability solution is a three point issue.
1. size. fit maximum conventional airline size this becomes less important as airlines carry properly boxed bike for free, but as i guy who hates luggage, my bike box sucks.
2. simplicity of dis and re assembly
3. methodology that retains weight, rigidity, quality, cosmetics, and durability qualities, and is not too expensive to integrate into manufacturing process.
i have not done the exact measurements to see what the optimum distances are, but based on the time i have devoted to this over the last two years, i think the solution not changing very much is found in cutting the bike in two at a point under the seat in front of the rear triangle, and creating a joint there that allows the brakes and driveline and cables to remain attached.
this is a 3 piece solution. seat, bike front, bike back. your whole take down would be take off pedals (and maybe one crank arm, unhoook handlebar from boom so it can be sideways, collapse boom to steer tube, remove seat and headrest (and tailbox) decouple front and rear. i think an s and s type coupler would work,
http://www.sandsmachine.com/ but i would envision one to follow the shape of the frame, not round and maybe a pair of studs and nuts but similar process on the joining faces, or a simpler sleeve system, and it may also be possible to use a seat mounting system to bring the seat mount to sleeve over that part of the frame to and fasten thru and thru to effectively add a splint over the joint. this is a mod that would not require any other change to the bike. so no change in tooling. CB could simply contract to add this as a frame option for x dollars.
i really need to have an extra v20 frame to test the ideas. i have a couple local guys who are much better fabbers and welders than i. maybe everyone should buy up my other bikes so i can fund buying a new v frameset.
if you did other changes to clean the bike up i could see some real options to make the bike smoother overall, and reduce weight and increase aero in general.
i think the most complicated issue to deal with is the rear hydraulic disc brake. can you make a flex point that allows the rear hose to be bent enough to put the two halves next to each other. i think you could make a little tiny metal flex tube to do this, but i don't see the current lines bending this much. quick release connections would lead to air and the need to bleed. i am not a hydraulic brake guy for bikes so this would not be an issue for me.
