Precision

Compact design

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

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.

Check all the information indicated on the sidewall of the tire (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 are also on the tire sidewall.
For example, 50-584 means your tire is 50 mm wide with an inner diameter of 584 mm (approx. 27.5 x 2.00).

How to choose your inner tube

Remove the old inner tube using a tire lever.

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 and position of your 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.
