Yasaka series
Yasaka Rakza rubbers compared
Rakza is Yasaka’s Super Tension family. Rakza 7 is the allround-spin reference; 9 and Z are more direct; X sits at the hard, fast end.
It is the practical Japanese tensor next to Butterfly Tenergy and Nittaku Fastarc: enough spring for club looping, less tour marketing, a street price that German and Nordic shops keep in stock.
