Gibson Replacement Rings
Gibson offers a variety of replacement rings for gymnastics and CrossFit use.
The RN-26400 is FIG approved for loo to high-level competition, as well as beginner training.
The CF-RN000 is also wood and meets FIG specifications (not officially FIG approved for gymnastics competitions).
CF-26400 is a black plastic ring, 1.1" in diameter. Great for training. These rings have a wood grain like texture that gives them great grip and feel that reduces the need for chalk and yet are very comfortable.
