This year’s Tour features fewer kilometres of time trialling than 2012’s. Even so, the stages against the clock may prove decisive.
As both technology and investment have increased in cycling, so too has the complexity of the time trial bike. With the ability to simulate airflow using a computer program rather than having to create a design and take it to a wind tunnel, bikes have become ever faster, even within the constraints of the UCI’s rules.
One such machine is the new Aerostorm from French manufacturer Lapierre. Ridden by the FDJ squad, it’s the very latest machine to be released and features most of the tried and tested aero tweaks such as the stem line integrating flawlessly into the top tube, and the back of the fork crown flowing into the down tube.
As you’d expect, Lapierrre has pushed things even further and incorporated the front brake into the fork crown for a slippery design that will continue to offer good braking performance.
At the rear, they have left plenty of space around the rear wheel to facilitate the new wider style of disc, such as this Pro Textreme version so that riders can benefit from the lower rolling resistance of 25mm tyres.
