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

You need to tighten your seat post correctly to make sure it stays 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 7Nm.   Take care not to exceed the maximum height indicated on the seat post.

Fitting your tubeless tyres

Before you get started, make sure you have compatible tubeless-ready tyres.  Our tutorial video shows you how to fit your tubeless tyres.

How to avoid a puncture

Riding around with worn tyres brings the following risks with it: Loss of grip. Greater exposure to punctures. In this article, we'll tell you how to avoid a puncture. 

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 0.5mm thick.

4 / Repairs

You'll find the answer you're looking for in the FAQ.

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 standard screw thread.  Please use the correct tool to take your pedals off as force needs to be exerted to unscrew them.
