TTFs on TrailBerm, Drop, Rock Face, Rock Garden
Sendero muy técnico, especialmente en condiciones secas. Combina algunas secciones de flow con rock gardens técnicos y empinados, raíces y varios drops naturales de piedra con paso alternativo. Mejor echar un vistazo antes de tirarle
Pasado 1⁄3 del sendero está la entrada al sendero A.C.A.B. y te puedes confundir de qué línea es cuál
Disclaimer
Sendero con mucha pendiente. Recuerda que necesitas buenas condiciones físicas y técnicas para bajar con seguridad y sin dañar el sendero
