Looks like the conversion kit makes it a switch rod:
” Temple Fork Outfitters introduces a most unique concept… Imagine a two-handed rod and a 4 piece nine foot rod that will fit in the same length case. TFO now has two lower rod sections designed to replace the single-handed grip section on existing 7 and 8-weight 9′ 4-piece TiCrX fly rods. With a total of 6 rod sections of equal length you can now have both, a great 9′ 4-piece traditional fly rod, and a 5-piece 11’3″ two-hander for easy overhead distance casting. Convertible rods.”
