In a nutshell

This foam pad is designed for occasional users wanting to improve at mountain biking. The support foam is soft with medium firmness. It provides good user comfort and protects the cyclist’s pressure zones for rides of up to 1.5 hours. 

Foam thickness: 13 mm (1/2”)
Foam density: 65 kg/m3 (4 lb/ft3)
Foam firmness: 25 kPa (3 1/2 psi).

A base layer with added comfort.

For carefree riding, plan ahead and keep the essentials handy:
- On your right, a secure pocket (17 cm x 15 cm [7" x 6"]) with a zipper that’s easy to open (even with gloves on!) so you can access items you need while riding with only one hand, such as your tissues, tire lever, etc.

One secure pocket

When mountain biking, gloves are often the last thing you put on and the first thing you take off. These shorts have a buckle on the waist so you can keep your gloves handy without putting them in your pockets. You can snap your ST 100 and ST 500 Gloves to the shorts with the press stud and keep them handy at all times.

Keep your gloves handy!

Ease of use

This self-adhesive patch kit lets you easily and quickly repair punctures so you can carry on enjoying your bike rides.

Tire Assembly

1. Remove the inner tube and locate the puncture
2. Roughen the area around the puncture using the sandpaper
3. Clean and dry this area
4. Apply the self-adhesive patch and press hard on the entire area for around 45 seconds
5. Run your nail over the patch to increase its adhesive power
6. Put the inner tube back in the tire and the tire in the rim
7. Inflate your tire to the recommended pressure.

User tip: 

Optimal lifespan: 3 years at room temperature (16-22°C, 30-70% humidity), away from direct light and in its original packaging.
Minimum temperature for repairs: +10°C 
Temperature for use: -40°C to +65°C

Storage:

Be careful not to touch the sticky part when positioning the patch, so as not to reduce its sticking power.
Remove any air bubbles by pushing from the centre of the patch towards the edges.
Rub the patch with your nail to warm it up and help it stick better.
Finally, press firmly with your thumb, covering the entire patch for 45 seconds to 1 minute (press on a clean, flat surface for greater effectiveness).

Applying the patch: 

A good sanding of the area concerned will give you a better result.
The aim is to obtain a flat, clean surface so the patch holds as well as possible.If the puncture is close to excess material, sand until the excess is removed.
Sanding will create micro-scratches that will allow the glue on your patch to set more easily.
This stage is very important for a lasting repair.

Sanding: 

Clean away any impurities to ensure a clean, flat, and dry area to apply the patch.
Remember: don't use water or any other product to clean your inner tube after sanding. It's essential to have a clean, dry surface to ensure that your patch lasts.

Contrary to popular belief, tamper-proof locks do not exist.
Bike locks are intended to act as a deterrent, makingit more complicated to steal a bike.

A good lock has an anti-picking lock mechanism and is made out of materials requiring the use of specific tools, which makes theft more difficult.

Safety

The security rating helps you choose the lock that’s best suited to your needs.
B'Twin devised test protocols based on real-life theft techniques with CNPP, an independent laboratory.
This unique protocol assigns each lock a theft resistance rating from 0 to 10.
