The G-max is a racing bike frame designed with a goal: to reconcile comfort and performance. By mixing in a same frame an aerodynamical monobloc front triangle with a rear triangle thought as an oscillating arm, plus a unique patented concept of BB with adjustable position, we have created a frame that really reconciles performance and comfort. The patented BB system enables to change the BB axle position thanks to removable interchangeable pieces. Associated to the G-max's seatpost, it gives the possibility to chose the virtual seat tube angle in an interval of 6.5° which gives to the G-max a unique adaptability (morphology, practice).
