Insert directly between the chain's links.

Ease of use

Quickly and easily read the degree of wear on your bike's chain.

Precision

Compact design

Designed for easily and quickly measuring the degree of wear on your bike chain.

Condition

Intensity

Place your bike on your workshop stand (for greater comfort) or against a wall.
Insert the left-hand side of the tool into a link on your chain (make sure the small hook is well inserted into the link), then lower the right-hand side onto the chain to read the result.
Once it has been properly installed on your chain, the chain wear indicator should lie as flat as possible.

How to use this tool

If the tip of the tool (the right-hand part) does not go beyond the line above the "OK" sign, then your chain and cassette are in perfect running order.
If you press the right-hand tip of the tool in between the 2 lines of the "1", then you need to change your chain.
If you press the right-hand point of the tool beyond the line at the start of part "2", then you need to change your chain and cassette or freewheel.

How to read your result

It all depends on how often you ride.
We recommend that you check the condition of your chain once a month to ensure that your gears shift smoothly and that you don't wear out your cassette or freewheel prematurely. That way, you don't have to change them more quickly than necessary.

How often should you use the tool?

Maintaining your drive train ensures that your gears shift smoothly, extends the life of your components, and eliminates unwanted noise. We advise you to follow the 3 recommended steps:
01) Degrease your drive train;
02) Clean your bike;
03) Lubricate your chain. 
You can find all our maintenance products on our website or in our stores.
Testing your chain wear regularly will prevent premature wear of your drive train.

Did you know?

This chain wear indicator is a precision tool. If the tool is dropped, this could affect its precision and the result obtained. 
Be careful when handling the tool and protect it from being dropped.

Etrto

Check the sidewall for tire information (diameter and width). For example, 27.5 x 1.90 means a tire with a 27.5” diameter that is 1.90” wide.
The dimensions in mm (ETRTO international unit) are also on the tire sidewall.
For example 50-584 means the tire is 50 mm wide with an inner diameter of 584 mm (or 27.5 x 1.90).

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 avoid punctures from pinching and for the best tire performance, we recommend checking your tires and inflating them to the suggested pressure before every ride.

- a snug, non-compressive fit that’s easy to forget 
- two easily accessible side pockets

The design of the Endurance shorts

The Endurance cycling shorts come with a new anatomical chamois pad. 
The central seam lets the pad fold. This construction technology ensures a perfect fit and stability in the saddle.

Developed for men’s bodies, it is made of stretch layers that follow your body’s movement when pedalling.

Anatomic Endurance pad

This chamois pad is made from a unique combination of materials that offer the protection you need on your long rides. Both in the ischial and perineal areas. It has a protective, high-density, 120 kg/m3 (7 1/2 lbs/ft3) foam insert. The top layer of fabric, which is in direct contact with the skin, is made from spandex and brushed polyester threads to prevent rubbing and irritation. 
All layers are extremely breathable.

Breathable, high-density foam

Cycling Pants and Overpants

Long-lasting rust protection in all weather conditions.

Corrosion resistance

Smooth pedalling

Lubricating the chain reduces disturbing noises.

Noise level

This lubricant is designed for lubricating your drive train during rides in all weather conditions.

Shake the bottle before use.
Only apply to the inside of the chain, i.e. the part in direct contact with the chainring teeth and the derailleur jockey wheels. 
Wipe off any excess with a microfibre cloth.

Advice from our team: 

To ensure optimal maintenance, we recommend that you follow these 3 steps: 
1. degrease your drive train
2. clean your bike
3. lubricate your chain

How to look after your bike:

This all-weather chain lube is designed for doing step 3. Once you've applied the degreaser (step 1), spray the bike with the cleaner and rinse and dry it (step 2), then apply your bike lube (step 3). Your bike will be as good as new.

How to use this product: 

Remember to degrease your chain before greasing it in order to remove any residue that could make abrasive contact with your drivetrain. This will help your equipment last longer and save you money.

RCR stands for Racer. This line of products is designed for cyclists looking for the best equipment. Versatile and uncompromising, it delivers excellence on all terrain, from flat sprints to mountain ascents.

Trusted by the Decathlon AG2R La Mondiale professional team.

The Mips® Air Node system is designed to protect against rotational impacts. In the event of an impact, particularly an oblique one, your head may rotate suddenly and violently, which is a common cause of concussions.

Mips® Air Node is an integrated, discreet layer that lets the helmet move slightly relative to your head. The system stays fixed during normal use, releasing on impact to dissipate rotational energy and reduce the risk of injury.

Mips® Air Node: safe, lightweight, and ventilated

Air Node is the most advanced protection solution from Mips®.

Benefits include:

Lightweight and well-ventilated: perforated and designed not to impede airflow.
Comfortable, with no pressure points.

Smart protection: only activates upon impact to deflect rotational forces.

Why Mips® Air Node

Because safety comes first, this helmet meets the highest impact standards and 

complies with European regulation EN1078. 
The standard covers construction (including field of vision), shock absorption, retention system features (including chinstrap and tightening devices), and marking and information.

Security

The size of a helmet is based on your head circumference. 

RCR:
Size S: 52–55 cm | 240 g (20.5–21.7″ | 8.5 oz)
M: 55–59 cm | 280 g (21.7–23.2″ | 9.9 oz)
L: 59–62 cm | 300 g (23.2–24.4″ | 10.6 oz)

Note: This helmet features the Mips system, which slightly affects sizing. If you’re at the upper end of a size range, we recommend choosing one size up.

Size and weight

Optimal ventilation occurs when large air inlets connect to exit channels that let the air flow freely. The head is an essential component for cooling the body during intensive effort.

The evacuation of the heat generated is thus a priority for maintaining a high level of performance.

Poorly placed vents can greatly increase drag and reduce aerodynamic performance.

The RCR has a variable ventilation system depending on your position on the bike. For example, when climbing a slope, the straighter up you are, the more effective the system. As soon as you tip down for a descent, the aerodynamics of this helmet will make all the difference.

Ventilation and aerodynamics

This helmet is personal protective equipment (PPE). The protection it provides depends on its condition.
We can only accept helmets returned in new condition. If your helmet doesn’t suit you, please return it with the user guide and tags.

Return conditions (specific to PPE)

Helmets don’t last forever. For maximum safety, we recommend replacing your helmet at least every 5 to 7 years. Be sure to store your helmet in its case, in a dry, cool place away from sunlight.
Extreme temperatures will deteriorate the helmet's foam more quickly.

Always replace your helmet after a major impact, as damage you can’t see may affect its protective ability.
