Mine are the records, one set is 3 years old and have over 15,000 miles on them, and one set is new this year and has 700 miles on them, they both feel the same, the old ones are just as tight as the new, I payed 189.00 for the old ones and the same this year for the new. The cleat uses a look bolt pattern but has a resin front section and a steel rear cleat. I haven't tried the chorus but they look similar.
