The Project 0.2 high rise extensions have been designed to offer 100 mm of height gain, when using the wedge and cup package. The complete Project 0.2 ecosystem is required for UCI compliance. "I have been so impressed with the quality, functionality and levels of adjustment with the Project 0.2 ecosystem. It's by far the best time trial cockpit system I have used. Achieving a comfortable, fast and aerodynamically sustainable TT position can often be a challenge. But the Project 0.2 ecosystem delivers the results every time." Matt Hallam.
