Salutare. Nu am vazut sa existe un review concret despre cadrul Octane one Zircus, care daca nu ma insel, este acelasi cu Ns Zircus. Din putinele pareri de pe alte forumuri, am vazut doar posesori multumiti, care il recomandau mai departe. Ca geometrie, ar fi un cadru un potrivit pentru persoane mai scunde interesate de dirt jump. Deci la noi are sau a avut cineva ? A incercat ? A auzit ceva despre ? The Zircus is an alloy all-round dirt frame perfect for playing in the city and off-road. It’s a lightweight and strong aluminium frameset with ‘Pro’ dirtjump geometry designed to fit 26” wheels, forks with 80-140mm travel and a single speed drivetrain. However the frame includes a removable derailleur hanger so you can convert the bike into serious all-purpose off-road machine with gears if needed. Designed for riders who prefer the feel of alloy frames. More slack and stabile than the radical steel Void frame. The BB is lowered for more stability, the top tube and chainstays are slightly longer than those in the Void and the headtube angle is more slack. Tough enough for jumps, perfect for pump-tracks, comfortable enough for trail riding.
