I know you will not find any mount for the QR15 that locks directly onto the fork. You can use a QR15 Fork Up with a cable with a loop at each end, make a noose around the downtube of the frame and the other end through the leg of the Fork Up which is locked into the locked fork mount of your rack. I custom made a few 2' long cables as described above and it works great.guerrero101 said:
