What checks do you need to make before going out on the bike?

What pressure should the tyres on your bike be?

The tyres are the only part of your bike that are in contact with the ground. It's important to minimise the risk of them losing grip, which is why it's important to make sure they are inflated to the right pressure. Check out our advice here:

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. We recommend you tighten it to between 6 and 7 Nm.

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

When to change your tyres

Riding with worn tyres comes with risks:

- Loss of grip

- Higher risk of punctures

In this article, we're going to help you recognise a worn tyre:

When to change your chain

The chain is an essential part of your bike's drive train. It is important because it connects the chainset and the cassette. It transfers energy so that you can move forward efficiently, so it needs to be in good condition. 

When to change your brake pads

To find out if your pads are worn, check the thickness of the brake lining on the pad. You'll need to change the pads if the lining is less than 0.5 mm thick.

4 / Repairs

You're sure to find the answer to your questions in the FAQs

Changing your 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.

Changing your inner tube

If you pick up a puncture, our tutorial will tell you how to change your inner tube.

Changing your handlebar tape

The tape on your handlebar will wear over time and you'll need to change it occasionally.

Your disc brakes are making a noise

If your disc brakes are making a noise:

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

- Check that the brake calliper is in the right position.

- Check the brake pads for wear.

- Check the tension of your brake cables.

Your bike isn't braking very well

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

- Use a degreaser to clean the disc.

- Check the brake pads for wear.

- Check the tension of the cable.

Changing your brake pads

It's important to change your brake pads before they become too worn. It makes for safe riding.

Changing your housings and brake cable

Your gears are skipping

If your gears are slipping, you need to check the following:

- Wear on your drive train.

- The tension of the cables.

- The derailleur hanger, to see if it's in line with the wheel.

You then need to adjust the derailleur.

Changing your chain

Here's some useful advice on how to change your chain correctly.

Changing your bike cassette

Is your drive train worn? Do you need to change the number of cogs on your cassette? Watch our tutorial to find out how to change your cassette.

Please note: the maximum cassette size for this bike is 11 - 34.

Changing your chainring

Is your chainring worn? Do you want to change the number of teeth? It's easy to change your chainring. All you need to do is use an Allen key to unscrew the screws holding the chainring in place. You can then fit the new chainring.
