The Features of the LOSA 4U23 Frame

Highest quality materials.Use of two types of unidirectional carbon fibers with a high degree of tensile strength Toray® T1000 HMF. Fibers are placed in frame parts to increase impact resistance to prevent frame breakage.
Optimization of Driveability.The 4U23 model features a tapered headset. This solution guarantees excellent driveability of the chassis.
Mixed comfort stiffness.The geometries of the 4U23 model were developed to make the parts where the power transfer between the runner and the frame takes place rigid in order to minimize energy waste. The frame was also designed to optimize the comfort of the runner.
Very low weight.The geometries of the 4U23 model were developed to minimize the weight of the frame and fork without compromising safety. The weight of the size M raw frame is only 1,000 gr.
Top aerodynamics.The 4U23 project was born with the concept of minimizing the resistant impact of the air flow on the frame. The optimization of the aerodynamics of the 4U23 model passes through the design of the tubes.
Elegant designs and liveries.The design of the 4U23 model is based on the elegance of the shapes and the liveries have been designed to enhance the shapes through the combination of geometries and colors.
