In reply to Removed User: "French free" means pulling on gear--whether fixed or placed--to get past a hard section.It arose out of the Alpine ethic of "speed is safety", so virtually "anything goes" if it allowed you to climb faster. Since for many years on the Continent(basically 1940s thru the early '70s at least)crags were seen in most areas as merely practice for "real'--i.e. alpine, climbing, this practice was utilized on them as well. The French even had a phrase for it "tire clou"--I believe, and you would see routes or moves described with "T.C." in guidebooks.Nowadays "obligitoire" has a similar implication, meaning the grade of the hardest move that you can't "frig" your way past.
