Every second counts in a Time Trial. Nothing can be left to chance.
When the FDJ cycling team turned to Lapierre’s engineers to work on the the latest iteration of the Time Trial bike: the Aerostorm DRS (Drag Reduction System), they had one goal: speed.
To achieve this goal Lapierre engineers set to work on improving the handling, braking and aerodynamics. Following two years of work by a crack team of Lapierre engineers, FDJ technicians, and a Pulsaéro aircraft engineer, the project is complete and FDJ team riders have received their new steed.
Handling : the geometry of the Aerostorm DRS has been completely reworked. The frames have been sized down, but with an increased top tube length, a steeper seat angle, and increased wheelbase. An aggressive race geometry for a winning position on the bike.
Braking : a new custom made central pulling brake has been specially developed for the Aerostorm DRS, with improved braking efficiency and aerodynamics. The brake is aligned with the frame and the narrow profile enables a smaller cover to reduce drag.
Drag Reduction System (DRS) : Airfoil profile tubes and a fully integrated cockpit offer maximum efficiency and speed. The frame, fork, stem and handlebar are fully integrated and have been conceived as one in order to reduce drag as much as possible. CFD testing, sessions in the Roubaix velodrome and in wind tunnels were followed by road testing in autumn 2015 by Steve Morabito and Thibaut Pinot.
Other features :
Made using the most advanced carbon construction methods. Latex bladders and silicone mandrels combine together to optimise moulding pressure and structural strength.
Rear triangle stiffness increased by 30% to optimise rider input.
Weight improved to make it one of the lighest TT bikes on the market. Version Team FDJ = 8.1kg in size M.
TDT (Trap Door Technology) – first used on the 2016 Xelius SL – this special patent pending Lapierre technology for placing the Di2 battery low in the frame with a quick and easy trap door to access it has been added following requests from FDJ’s mechanics. TDT makes the mechanics job faster and lowers the centre of gravity, making pedalling more efficient.
A special guide in the seat tube has been developed for the outer cable casing, with an easily demountable cable stopper. This makes the maintenance easier and further improves the aerodynamics.
Fully adjustable rider position: 3 different stem lengths (65/85/115mm), and a saddle position adjustable by 10cm.
UCI approved frame.
