BRAKES: bedding them in is essential

When using the bike for the first time, you should take time to bed the brakes in to improve your braking performance. This video will show you how to do it.

POSITION: the right position

It's important to find the right position so that you feel comfortable on your bike. Check out our tips below, and feel free to adapt your position based on your feeling on the bike.

TYRE: the right pressure

For gravel riding, the tyre pressure has to be just right because the bike will be used on a range of surfaces. You'll need to adapt the pressure based on the total weight, the type of terrain and the tyre itself. On your particular bike, we recommend following the advice in the link below.

These numbers are for reference only. You're more than welcome to experiment and adjust the pressure based on how it feels as you ride.
You'll find the minimum and maximum pressures on the tyre's sidewall.

SEAT POST: Tightening the seat post

To set your saddle correctly it needs to be securely in place. A loose seat post can slip when you're out and about on your bike. Conversely, if it's too tight, you run the risk of crushing the seat post and damaging your bike.

The best way to tighten a seat post is to use a torque wrench, which you will find in the box of your gravel bike. We recommend you tighten it to between 6 and 7 Nm.

Take care not to exceed the maximum height indicated on the seat post.


If you're not going to be using your bike for a long time, you should:

- Store your bike somewhere cool and sheltered

- Clean your bike to remove mud or sand.

- Lubricate the chain.

- Set the derailleur to the small cog

- Your bike is tubeless, so remember to add sealant every 6 months. If the wheels don't turn for a long time, the liquid can solidify and stop working.


We recommend wearing a helmet and gloves while riding. Anyone can take a tumble, and you'll be grateful for your helmet and gloves when it inevitably happens!

Servicing your GRVL GCR will keep all of its parts working for as long as possible and ensure you have the most fun when riding. Aside from the aesthetic aspect of having a clean bike, failing to service it can lead to problems that can cause malfunctions: jammed cables, rust, leaks, premature wear, etc.

Extending the lifespan of your bike's parts means a lower environmental impact.

We offer a free tune-up for your bike in the 6 months following purchase. 

With a gravel bike, you're going to be riding on both roads and mud. At some point, you'll have to change various components to keep your bike in good nick.

BRAKES: how to adjust your brake callipers

To adjust your brake callipers, we recommend contacting your nearest workshop.

BRAKES: changing your brake pads

To replace your brake pads, we recommend contacting your nearest workshop.

CASSETTE: changing your cassette 

To change your cassette, you'll need the right lock ring and a chain whip. You'll find both of these tools in the link below. 


To do this, you will need: a chain tool, a new chain, and a quick-link.

Place the chain on the last cog and on the smallest chainring. 

Remove the quick-link using the pliers or chain tool, then take the old chain off the drivetrain.
IMPORTANT: certain SRAM Force and Rival chains are directional.

Place the new chain on the last cog and on the smallest chainring. This will make it easier to determine its optimal length.

The chain should pass close to the top pulley of the upper jockey wheel on the derailleur.

Once you've determined the correct length, use the chain tool to cut the chain.

Lastly, install the quick-link onto the chain, turn the pedal so as to position the quick-link on the upper part of the chain, and use your hand to apply pressure and ensure it is firmly locked in place.

Need equipment to repair or maintain your bike? Here are the essentials.


Have you suddenly encountered a mechanical problem, or are you struggling to service your bike somehow? We've created a range of tutorials covering the most common maintenance jobs that you're likely to have to do.

PEDALS: mounting clipless pedals 

Are your pedals broken? Do you want to change your pedals for clipless ones? Here's our advice.

NB: please note that the screw thread on the left pedal is inverted and that the pedal thus screws on in an anti-clockwise direction. The right pedal has a normal thread.

Make sure to use the correct tool to remove your pedals as you will need to use some force to unscrew them.

BRAKES: the disc is making a noise

If your disc makes noise:

- Check that your wheel is properly centred. To do this, loosen the wheel and tighten it up again.

- Check that the disc is straight.

- Clean the entire brake system with water. If necessary, clean the discs with some water and soap.

The brakes might make a noise if they haven't been bedded in properly. In this case, follow the bedding-in procedure.
If you've been braking very hard over a long period (for example, when going down a steep hill), your brake pads might have glazed over and/or your disc could have overheated. In this case, replace your brake pads and discs.

BRAKES: if they aren't braking very well

There are several things you can do if your brakes aren't working as well as they used to:

- Clean your bike, discs and brakes with soapy water

- Check your brake pads for wear.

- Check that the calliper is properly centred.

- Have the oil purged at a Decathlon workshop.

Derailleur hanger: how to replace it

To replace your derailleur hanger, make an appointment at your nearest workshop.

WARNING: your gravel GCR SRAM RIVAL RR9 has a specific derailleur hanger, which you can find on our spare parts page.
