KYE FITZ 7.25" SINGLE FIN - CLEARKYE FITZ 7. 25" SINGLE FIN CLEAR Kye Fitzgerald's 7. 25" fin is a powerful full base fin designed for drive and power. This fin will work best for boards ranging from 6'6" to 8"0 in length and can be easily surfed as a straight single fin or combined with the KF2 sidebites. The KF2 sidebites are small enough not to take anything away from the single fin glide, but still, just enough surface area to hold the tail in on critical parts of the wave when
