The Salt City Derby Girls are going banked-track this year, a faster (and, subsequently, more dangerous) style of play currently practiced by only a handful of leagues in the U.S., such as Austin's TXRD Lonestar Rollergirls and L.A.'s Derby Dolls. To promote their debut banked bout at the Salt Palace on Saturday, May 5, SCDG and American Xtreme Wrestling produced this video. Better buy those tickets now.
