I'd love to sell them small scale, the only problems is that the holes need to be drilled accordingly, as I'm sure all frames are not the same, and the frames need to be drilled too. When I get a new chain(old one is no longer long enough and I don't have any spare links laying around to throw on there <_<), I plan to do some real testing. try and get a straight 50-100 miles on it nonstop. I'm definitely not worried about the strengths of it. The actual track ends are 1/4 inch 7005 aluminum. The bolts and hardware fastening them are 3/8 inch zinc plated, heat treated steel, including external teethed lock washers. The bolts go through the frames actual drop out, and through the derailleur hanger hole. I had to drill the non-drive side drop out to add a hole, it shouldn't add any structural problems, or the manufactures wouldn't have done it on the drive side, haha. depending on how the testing goes, I may actually start selling them.

my main concern is the bolts loosening with prolonged use. I'm going to see how the lockwashers do, and a hefty amount of loctite.

thanks for the compliments guys.
