Bottles
Bottles for road and gravel, chosen with the cage that carries them. Volume, shape and material depend on your pace, the length of the ride and the space on the frame.
A flat bottle for speed
A round bottle on the down tube is a cylinder across the wind. The Kreuza Slice is flattened to follow the line of the tube, and Kreuza tested it in the wind tunnel: 2.6 W less drag than a round bottle at 45 km/h. Aerodynamic power follows the cube of speed, so the gain shrinks as you slow down: about 1.8 W at 40 km/h, 0.8 W at 30 km/h. It counts in a fast group and in racing, on top of what the frame and wheels already gain.
A bottle is chosen with its cage
A flat bottle needs a cage made for it. The Slice sits in the Slice bottle cage, designed for its profile, which also holds a standard round bottle the day you need one. So you fit one cage for both uses. The other cages are under bottle cages.
Material and care
The Slice is made of BPA-free food-grade polypropylene, UCI compliant, for 620 ml and 84 g. A practical tip: rinse it with hot water after a sugary drink, before the sugar dries in the cap, and leave it open to dry. On a long ride, count the water points before you count the bottles.
When two bottles are no longer enough
Two 620 ml bottles carry 1.24 L. A large frame bag often takes the place of the bottle cages. For hot stages, the Hydration Vest 01 carries up to 2 L on your back and leaves the triangle free.
Frequently asked questions
Which bottle size should I choose?
For the road, a bottle of around 600 ml fits every standard cage and lasts one to two hours depending on the heat. Beyond that, add a second bottle or extra water in a bag or a hydration vest.
Does an aero bottle fit a standard bottle cage?
The Kreuza Slice is flattened and sits in its own cage, the Slice bottle cage, which also takes standard round bottles.
How do I clean a cycling bottle?
With hot water after every ride, especially after a sugary drink, with the cap taken apart if possible, then left to air-dry, open. Sugary residue drying in the cap soon leads to a taste and mould.
