TTFs on TrailBerm, Drop, Ladder Bridge, Rock Garden
Trailu převážuje charakter flow s utaženějšími klopenými zatáčkami a drsnějším povrchem.
V horní druhé čtvrtině je technické místo, kde je za sebou příkrá lávka, malý drop a příkrý rock garden v zatáčce.
Místně značený jako černý.

cool rock section which makes the trail "black difficulty". the rest of the trail nice to ride, nothing difficult
denisovic88
Určitě souhlas, že černá je jen jedna část, prudký mostek, pak rychle zatáčka, pidi drop z kamene a po kamenech dolů okolo stromu. Rozhodně to není pro každého, ale chápu, že pokud má někdo naježděný DH tratě všude po Česku nebo i zahraničí, tak ho to nijak nevzruší. Každopádně si myslím, že označení černá je asi v pohodě, trail by měl být pro bezpečnost značen tak jako jeho nejhorší pasáž aby se pak nějaký začátečník nedivil. Kromě zmíněné pasáže jsou tam pak už opravdu jen klopenky ve flow stylu, víceméně modrá...

Souhlasím, těžké je to je jenom na dvou již zmíněných místech. Jen je lepší tam nejezdit za mokra.
We hope you've been enjoying Trailforks!
