He offers 2 sizes of the Cateye Quick-Release mounts at a better price than I could find elsewhere. They work fine even on odd-shaped seatstays. The cross-section of my carbon bike seatstay is kinda diamond-shape, but the round mount worked fine with little pieces of inner tube rolled up and inserted to fill the "valleys".
So I have four of the mounts, one on each of my four bikes. Moving the taillight from one bike to another takes about a minute.
