At a cent shy of $120 per bottle and cage, Trek’s new RSL Aero setup is a pricy upgrade, but one that might be worth paying to acquire extra speed, given that Trek says they will make any bike faster.
‘We can’t give exact figures because they’re dependent on the individual bike, but the system was launched with the Madone Gen 8 and imparts a 1.8-watt advantage at 35kmh on that bike,’ says John Davis, the Madone’s lead aerodynamicist.
The bottles act a bit like a fairing, smoothing airflow across the bike’s main triangle. And while the Aero bottles will only work with Aero cages, the cages will accept regular bottles as well.
