THE ULTIMATE C-SHAPED KITEThe F-ONE WTF!? is a 5 struts C kite designed to excel in freestyle kiteboarding. Pure C Kite – five struts, high aspect ratio Amazing pop, slack and control Incredible Power and performance Fantastic stability The ultimate kite to excel in freestyle kiteboarding .progress-container { display: flex; justify-content: space-between; background-color: #f9f9f9; padding: 40px 25px 60px 25px; } .progress-ring { width: 150px; height: 150px; position: relative; text-align: center; } .progress-ring circle { fill: transparent; stroke: #ff6800; stroke-width: 15; transform: rotate(-90deg); transform-origin: 50% 50%; transition: stroke-dashoffset 0.5s; } .progress-ring .ring-background { fill: transparent; stroke: #ccc; stroke-width: 15; transform: rotate(-90deg); transform-origin: 50% 50%; } .progress-text { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); font-size: 24px; } .progress-title { font-size: 20px; color: black; margin-top: 10px; } @media (max-width: 768px) { .progress-container { flex-direction: column; align-items: center; } .progress-ring { margin-bottom: 50px; } } The C-Shape itself has always been the best option for making an easy to control and dynamic kite. We decided to add a 5th line to help with control, optimise the power and enable riders to relaunch the kite quickly with minimal effort. The kite’s pop is huge and the slack which follows is sudden and gives right enough time for the rider’s multiple passes. The WTF!? pulls you then out of your trick with speed and stability. The Kite’s profile has been improved in order to reduce the heavy sensation in your bar whilst keeping the excellent bar feedback from the previous edition. The kite moves better in the window and generates more speed in the low end. The kites are also highly tunable. There are three tuning options on the front lines; these allow you to adjust the kite to fly according to your level, riding style and the conditions of the day. Three rear line tuning options enable you to tune how the kite feels at the bar and adjust the handling too.
