Main Material

Clean your water bladder after each use. 

To help you clean out the tube, you can order a special brush (ref. number 5935596). 
This kit comes with a hanger to make it easier to dry out the inside of the bladder.
Tip: If you don’t want your drinks to taste like plastic, wash the bladder, dry it well, and place it in your freezer. 
Take it out a few hours before your ride. This will stop any flavour transfer.

Maintenance tips:

This hydration pack comes with a 2 L water bladder. But also remember to bring:
- food (granola bars, energy gels, etc.)
- a multi-function adjustment tool (ref: 8386669)
- a puncture repair kit (inner tube, tire lever, hand pump, puncture repair spray, CO² cartridge, etc.)
- a chain rivet extractor and a quick link
- a piece of identification (blood type card)
- a means of payment and a telephone
- a first aid kit


What to bring with you

The 2-litre capacity means your water bladder will give you hydration for around 3 hours of riding. 

The wide opening makes it quick to fill up. When closing it, make sure the slider clips into place so it doesn’t leak.

A large water bladder

Before you set off, remember to remove the air to improve water flow. 
Once filled, just turn the hydration bladder upside down, direct the air bubbles toward the tube opening, and suck them out. 
The bite valve locks (rotates 180°) to prevent leaks when not in use. It won’t drip, even in the open position. 
To get a good flow when drinking, pinch the valve with your mouth and suck.

Great water flow

To make your bag last longer, we recommend waterproofing it before you first use it. Even though the fabric is already water-repellent, extra waterproofing will stop mud from getting caked onto it. 

Before each ride, remember to wash and dry your water bladder with the cleaning kit (ref. number 5935596). Place your dry water bladder in your freezer overnight to get rid of any plastic taste. This will stop any flavour transfer.

Care instructions

Composition, dimensions, and care

To improve water flow and stop the water sloshing around inside the bladder during your ride, we recommend releasing any air before you set off!

Once filled, just turn the hydration bladder upside down, direct the air bubbles toward the tube opening, and suck them out. And hey presto, you can now drink quickly and quietly as you ride!

Removing the air


To avoid a plastic taste when drinking, rinse the product three times before first use. We recommend cleaning it after every ride using the cleaning kit (product ref. 5935596). 
After cleaning, leave the hydration bladder upside down and open to dry thoroughly.

If it still has a plastic taste, place the dry hydration bladder in the freezer for one night.

Bag details

The design of the semi-rigid flask is inspired by water bottles.
It has a screw cap and is marked so you can easily fill it to the desired level, up to 1 litre of water.

Unlike standard thermobonded water bladders, the walls are separated and help any remaining water drain (from top to bottom) out at the end.

This means no water remains in the flask, eliminating odours.

A really practical flask

Access the main compartment from the top. The semi-rigid flask is on a hook so it won’t drop to the bottom of the bag. 
You can store your money, keys, phone, snack bars, and tissues in the zippered front pocket. 
The reflective strip on the front of the bag shows where the pocket is.

Carry all your things

Clean your flask after each use. 

To help you clean out the tube, you can order a special brush (product ref. 5935596). 
This kit comes with a hanger to make it easier to dry out the inside of the bladder.
Tip: If the plastic taste lingers, place the flask in the freezer for one night. 
Take it out a few hours before your ride. This will remove the plastic taste.
