Bike Bags & Backpacks

It effectively protects your lower back from muddy spray.

Non-messy

Fits to its screwed-on bracket in just one click and keeps its position setting

It fits 26" to 29" mountain bikes with 25.4 to 34.9 mm (1 to 1 1/3") seat posts.

It has a "fuse" arm that comes unclipped in the event of a really big impact

Robustness

This 26" to 29" mudguard is designed to protect your lower back and bum from muddy spray kicked up by your rear wheel when mountain biking.

Wheel Size

This wide, impact-resistant mudguard stops mud getting sprayed onto mountain bikers' lower backs and bums.
Place the mudguard's blade as close as you can (2 to 3 cm (4/5 to 1 1/5") from the wheel.

You can't avoid muddy splatters completely when it's damp...
But for getting from A to B, if your bike's frame and your tire width allow, we recommend using a hybrid bike mudguard (with longer blades that are closer to the wheels).

Level of protection

This mudguard fits all 26" to 29" mountain bikes, with tires up to 2.8" wide in 27.5", and 2.6" wide in 29".

To ensure a good fit, the diameter of the seat post must be between 25.4 and 34.9 mm (1 and 1 1/3").

Bike compatibility

The fender comes fully assembled and ready to be installed.

Box contents

Designed to fit all the new wheel and tire sizes on the market, and with a bold design, our mudguard gives your bike a modern, dynamic look.

Everything has been designed to give you the best experience:
- A reliable screw-on bracket that holds the mudguard in the same position each time
- An easy system to clip the blade onto and take it off your bike depending on the weather
- "Fuse" arm to stop it breaking
- Compatibility with accessories (camera, lights)

A modern, efficient design

In dry weather, when there's no rain and mud about, you can unclip the blade from the bracket and clip a sports camera on instead. The camera must be compatible with the GoPro bracket system.

To keep you safe when riding early in the morning or late at night, there's a rail at the end of the blade that you can clip a CL 100, CL 500, CL 900, ST 500, or RL 510 LED rear light to.

In a nutshell 

The snaps let you keep the gloves together. Why? So you can lay them over your handlebars as you get ready to ride. 
To clip them to our new ST 500 shorts when taking a break.
So you never have to look for that missing glove in the laundry pile or the drawer. 

Smart mountain biking gloves: Two snaps 

The thumb area is made from terry cloth to absorb perspiration. 

Terry cloth for perspiration

Mountain biking gloves are important for your safety all year round. 
Keeping your hands covered all the way to the fingertips is key to preventing scratches from vegetation, especially in the woods or on single tracks. Even more important, when you fall, your reflex is to put your hands out to cushion yourself. Mountain biking gloves prevent scratches and absorb vibrations. 

Why should I wear mountain biking gloves in the summer? 

Based at the B’twin Village in Lille, our product design team works constantly to make biking more comfortable for our users.
Our goal is to create products that respond to our users’ needs and foster a good cycling experience.
