Trek RSL Aero Water Bottle and Cage

Some aero bottles don’t perform well as water bottles. How is the RSL Aero Water Bottle different?

We designed the RSL Aero Water Bottle to have the excellent squeeze and flow riders expect from a high-quality cycling bottle while saving watts and fitting perfectly with the cage and Madone Gen 8 frame.

How does this bottle make Madone Gen 8 more aerodynamic?

We tested the RSL Aero Water Bottle and Cage on the Madone Gen 8 in the wind tunnel to find 1.8 watt savings at 22 mph (35 kph) compared to standard round bottles and standard cages. The 1.8 watt figure is the weighted average across the tested yaw angle sweep.

How does this bottle make all bikes more aerodynamic?

We tested the all-new aero bottle and cage on a variety of race bikes, from Trek and other brands. Through this testing, we found a meaningful aerodynamic advantage on all bikes tested compared to standard round bottles and cages.

Are the RSL Aero Water Bottle and Cage UCI Compliant?

Yes!

Yes! The RSL Aero Bottle Cage can securely hold the RSL Aero Water Bottle and standard round water bottles due to its clever design. This allows riders to train with round bottles and accept round bottles on rides without swapping cages. When the speeds get high and every watt matters, riders can use the RSL Aero Water Bottle to gain every aerodynamic advantage possible.

How much does the RSL Aero Bottle Cage weigh?

35 grams

Does this carbon cage qualify for the Trek Carbon Care program?

Yes! Through Carbon Care, Trek offers a significant discount to replace damaged carbon parts. Bring your damaged part into your local Trek retailer to receive a replacement at a discounted price.

Are bolts included with the bottle cage?

Yes! The RSL Aero Bottle Cage must be installed with the included button head bolts.

How do I install the RSL Aero Water Bottle and Cage to maximize aerodynamic effect?

For Madone Gen 8, install the seat tube cage first with the bottom of the cage as close to the bottom bracket as possible. Then, install the downtube cage with the bottom of the cage for the bottom of the cage to be 1 cm away from the seat tube cage. Minimizing the gaps between the frame and bottles will help you maximize aerodynamic efficiency. For other bikes, follow the same process as Madone Gen 8.

What’s the recommended torque to install the RSL Aero Bottle Cage?

The Madone Gen 8 max torque for bottle cage bolts is 2Nm (17.7 lb-in). Most Trek bikes are 2.3-2.9 nm (20-25 in/lbs.).
