Water Bladder Volume

Main Material

This 3 L (2 1/2 qt.) water bladder is compatible with the ST 900 mountain biking hydration backpack (ref. 8300158 )

With a 3 L (2 1/2 qt.) capacity, your water bladder will last you around 4 hours. 
It’s quick to fill because of its wide opening. When closing it, make sure the slider clips into place to ensure that it won't leak.

Ride with peace of mind

You can cut the tube to the most convenient length for you. 
Remove the bite valve, place the tube in hot water to soften it, cut it to the desired length, and put the bite valve back on.

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, gently bite the valve and suck.

Adjustable tube and valve for increased comfort.

The materials used to make this water bladder are guaranteed to be free of bisphenol A (BPA).

40 x 19.3 cm (16 x 7 1/2"), 100 cm (40") tube.

To make your water bladder last longer, we recommend not folding it, not filling it with hot liquids, and not carrying it upside down or by its tube ;)

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.

How to clean your water bladder

To check this water bladder's quality, we've tested it thoroughly in our in-house lab.
Besides spotting no defects during our burst / high pressure tests, we noted an increase in puncture resistance of more than 74%.The water bladder is made in France, which means we can closely monitor production quality (for watertightness and sturdiness over time).

Tested, approved, and made in France!

Check all the information indicated on the sidewall of the tire (diameter and width). For example, 29 x 1.90 means that the tire is 29 inches in diameter and 1.90 inches wide.
The dimensions in mm are also on the tire sidewall.
For example, 50-622 means that the tire is 50-mm wide with a 622-mm inner diameter (approx. 29 x 2.00).

How to choose your inner tube

Remove the old inner tube using Btwin tire levers.

Removing an inner tube

Check the condition of your tire and replace it if necessary. 
Make sure no objects are lodged in the tire.
Check the condition of your tire rim strip.
A rim strip that’s even slightly bent can cause punctures.
Check that your rim doesn’t have any other issues that could damage your inner tube.

Checks to carry out before installing an inner tube

Watch our video before you start.
Pre-inflate the inner tube slightly to avoid pinching.
Make sure you’re using the correct valve for your rim and then insert it.
Put the entire inner tube inside the tire so that it fits inside the rim.
Take care not to pinch the inner tube when installing it.

Installing the inner tube

Start installing the tire at the valve.
Finish installing the tire across from the valve to avoid pinching the inner tube.
Never install your tire with a tool or a tire lever, as you risk pinching or puncturing the inner tube.

Installing the tire

Carefully inflate your tire to the pressure recommended by the manufacturer (visible on the tire sidewall in PSI or bars: 1 bar = 14.51 PSI).
Regularly check that your tire is in the correct position as you inflate it.

Inflating the tire

To prevent pinching and achieve the best performance, we recommend checking and pumping up your front tire as needed before each ride.

Bike Tubes & Valves

The notched shape of these pedals means they grip any kind of shoe.

Weight

Our 100 flat pedals are made from resin and designed for adults doing recreational mountain biking or riding a hybrid bike.

Pedal Type

These pedals have a 9/16" (1.4 cm) standard thread that is compatible with all adult mountain, hybrid, city, and road bikes on the market.
Our 100 flat resin pedals are compatible with universal cleats ref. 8486938

Bike and cleat compatibility

To mount the pedals, you’ll need a 15-mm (3/5") wrench or a 6-mm (1/4") Allen key.
Make sure you screw each pedal on the right way: clockwise for the right, and counterclockwise for the left.

Mounting

Dimensions of the flat part (excluding reflectors):
Length: 95 mm (3 3/4")
Width: 70 mm (2 3/4")
Thickness (including the height of the studs): 32 mm (1 1/4")

Dimensions

Avoid pushing through your heel or arch as you pedal as this can lead to pain and fatigue over time.
For improved comfort and more efficient pedalling, position the ball of your foot just above the pedal’s spindle.If you need help achieving the right position, cleats can help.

Instructions for use

There's nothing more visible at night that a moving, lit-up object.
With reflectors on the front and back, our 100 flat mountain bike pedals help make you even more visible to other road users.

Because they are made from resin, the 100 mountain bike pedals are less likely to injure your shins and calves if the pedal spins back unexpectedly.
