Trek Madone 4 road bike series

Trek includes its 4 series road range in the popular custom programme, Project One.

Trek’s ever-popular 4 Series continues as a three-bike range for 2014, with the brand including this model in its popular custom programme, Project One.

Using 400 Series OCLV (Optimum Compaction, Low Void carbon manufacturing process), the chassis is the first in the Wisconsin firm’s Madone range to use Kamm Tail technology. Derived from the motor industry, Kamm Tail aerodynamics feature on the frame and forks, sharing this design with higher-spec Madone models and, specifically, the Speed Concept time trial series machines.
