The Aero Hydration System is compatible with many bike models. For certain models (Canyon Speedmax CF, Cervélo P-Series) you will find an allocation according to frame size etc. here.
For all other models, you will find an overview of the technical requirements below as well as fitting templates with which you can select the suitable model (S1 / S2 / S3 / S4 / S5).
The Aero Hydration System is compatible with the original stem of the Speedmax CF from 2017 (year of manufacture) onwards. Please note the different allocation for models with disc brakes (disc) and models with rim brakes (previous model). You can find the stem length on the side of the stem, next to the label "V21".
Please note: the system is not compatible with the integrated cockpit of the Speedmax CF Disc 2024
* Since this model is also compatible with 10mm shorter stems, the gap between the bottle and the frame is 10mm larger than in our pictures.
** Spacer below stem refers to the component pictured below.

**Spacer below stem
The Spacer below the stem (see picture) is required for some models. If it is removed, the remaining space is not sufficient for some models.

The Aero Hydration System is compatible with the original stem of the Cervélo P-Series. The table refers to the standard setup (stem length) for the respective frame sizes.
For frame size 51, model S1 is compatible with a spacer height below the stem of minumum 15mm (model S4 fits below 15mm). For all other frame sizes, the spacers are not relevant.
Di2: The Aero Hydration System takes up the space below the stem. The junction box may therefore have to be placed differently (e.g. on the stem / in the bento box).
If you have made changes to the stem (e.g. different stem length), we will be happy to advise you (contact form).

Your bike must have a 4-bolt stem and enough space to mount the hydration system. For optimal integration into your cockpit, you can choose from five shapes (S1 / S2 / S3 / S4 / S5).
Please check the following technical requirements:
The bolt heads of the stem bolts must be fully visible.
The Aero Hydration System is not compatible with stems with deeply recessed bolts. A flush / non-positive assembly is not possible in this case.
There are a few exceptions, such as the Cervélo P-Series stem, which is compatible due to the special geometry of the front plates although the bolts are recessed.
Stem alternatives are listed here.
The bracket is mounted on the lower bolts of your
4-bolt-stem.
Please measure the outer distance of the bolts either on the bolt head (21 - 39mm) or on the thread (18 - 36mm).

The system requires sufficient space from the lower edge of the bolt heads downwards (installation height). You can choose from five shapes depending on you cockpit geometry and frame size:
Please measure the distance to the center of the rim brake (for disc brakes to the tire). We recommend to use our fitting templates.

The system follows the stem and has the same inclination. It fits optimally on stems that run horizontally. This corresponds to an inclination (angle to the head tube - see sketch) of -17°. You find the corresponding information in the description of the stem.
The minimum length of the stem depends on the shape of your frame. Please use our fitting templates, to find out, if your cockpit offers sufficient space.
If you are uncertain, please send us photos of your cockpit and the fitting template from the front and from the side.

The Aero Hydration System fits many stems. The following selection is compatible in terms of shape and bolt spacing.
Some stems can be mounted both sides. The inclination can therefore be interpreted as +/-.
Please note, that the Aero Hydration System follows the stem and has the same inclination. We do not recommend inclinations between 0° and -5°, as the bottle is a little too steep in this range. Optimal are horizontal models (inclination -17°). Downward tilted stems with an inclination greater than 17° are not suitable.
Some models are available with various inclinations. In the table below, we only show the relevant versions from 6° to 17°.
Stem | Inclination in ° | Length in mm |
---|---|---|
Canyon V21 | 17 | 70 / 80 / 90 |
Cervélo P-Series Stem | 7 | 70 / 80 / 90 |
