Check the information indicated on the sidewall of the tire (diameter and width). For example, 27.5 x 2.20 means that the tire is 27.5" in diameter and 2.20" wide.
The dimensions in mm (ETRTO international unit) are also on the tire sidewall. For example, 50-584 means that the tire is 50-mm wide with a 584-mm inner diameter (approx. 27.5 x 2.00).

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.

Ab Wheel description

We recommend using the In & Out Mat when doing sets with the Ab Wheel (ref: 8873350) to avoid knee pain.

Stay comfortable during ab exercises

Getting started and want to improve? Try our adjustable Ab Wheel (ref: 8556755).
Already done a few workouts with the adjustable Ab Wheel and want to amp up the difficulty? Opt for this ab wheel.

Choosing your ab wheel

Using the Ab Wheel 
- Kneel down on a mat or cushion.
- Grab hold of the two handles.
- Keep your knees on the floor while pushing the wheel forward until your arms are straight.

How to use the Ab Wheel

This accessory is a must-have for strengthening your abs. It trains both visible muscles (six pack) and deep muscles. Core work can improve your posture and strengthen your abdominal muscles. 

Proper technique is important to avoid back pain when using the Ab Wheel!

Why the Ab Wheel is so essential

We redesigned the Ab Wheel so it can be used by even the most experienced athletes.

But what really changed? We made the unstable mode much more unstable so that seasoned athletes can keep challenging themselves!

Why use the dual mode Ab Wheel

A strong core is essential for all sports, but also in everyday life. It improves your posture and strength while preventing injury and helping you feel better while doing everyday chores. 

Working the abs, obliques, and lower back strengthens your entire core. Without these muscles, you wouldn’t be able to stand up straight.

Why you should strengthen your core

Prevent injury by flexing your core and keeping your back flat, not arched. Tucking in your pelvis will help. 
Avoid pushing yourself too far forward. Train in front of a wall or door that will act as a barrier to prevent too wide a range of movement. 
The Ab Wheel is not recommended if you have back problems or are not used to working your abs.

Packaging

Wool fibres can store a lot of air and let water vapour escape, making wool an excellent choice for moisture management and thermal regulation. Wool’s ability to store and release moisture make it an insulating, comfortable material for hiking socks.

The properties of wool

The merino wool, from Spain, has been a carefully selected breed for generations because of its wool. It provides a softer fibre than traditional wool. After shearing, the wool is cleaned to remove impurities, then carded, spun, and finally used for knitting or weaving.

What is merino wool?

Merino wool offers an unbeatable experience: soft, lightweight, and breathable. Thanks to its fine fibres, it provides natural thermal regulation. It keeps your feet warm in cool weather and cool in warm weather.

What are the benefits of merino wool?

To stay warm when hiking in the winter, we recommend: 
- Warmth: wear warm socks (ideally with a good percentage of wool). 
- Breathability: choose socks based on the intensity of the hike and, to minimize moisture, make sure they’re breathable.
- Boot height: the height of your socks should correspond to the height of the boot: for more protection, choose higher socks.

How do I choose the right footwear for hiking in the snow?

These socks come in packs of 2 pairs of matching socks.

Pack of 2 pairs

The stretchy fabric means these socks conform to your feet and stay firmly in place. Given that the length, width and volume of our feet is always different, we advise trying on your socks in store before purchase, and testing them before going on a long hike.
