Overlap is something you are going to have no matter what. Depending how much offset the fork has, you can get another FGFS fork with more offset. Most of those forks have 32mm of offset.
If you are looking for no overlap at all whatsoever, you will need a real FGFS frame and fork with 26 inch wheels. Also some of the 700c FGFS frames have super long top tubes, but they all have some overlap when the wheel is turned around.
I have an SE Landing fork (
http://www.danscomp.com/products-RAC...Gear_Fork.html) which has a 29mm offset. Landing gear also makes another fork (
http://www.sebikes.com/part.php?id=1876) that has a 36mm offset. That would give me an extra 7mm, which is just about what I need.
I did a measurement, where I put my feet in the straps of the current pedals I have, and then rub the tire on the soles of some white shoes where it overlaps the most, and then measure how far the black mark is from the front of my shoes, and with the wheel forward its about 6.5mm and with it backwards is about 7mm.
I'm not sure my measurement is correct, because I would think backwards would be a bigger difference than just .5mm as the offset (which I am assuming is how far out the wheel is pushed) should be "pushed in" when the wheel is backwards. I don't really get how the overlap is so close (i.e. 5mm) between the wheel being forward and turned around.
But, perhaps a fork with a greater offset along with pedals that allow me to comfortably put my feet back a few mm would give me the space I need. What do you think about 160mm crank length instead of a 165mm crank length I have now?
Besides the particular clearance issue that I have discovered by trying to use a track frame for a FGFS, what else does the FGFS geometry provide that the track frame geometry does not?
Anyway, I appreciate the info. Gives me something to think about/consider.
