LIGHTWEIGHT, COMFORTABLE AND PLAYFUL FRAME
It isn't always easy to get the right position on a mountain bike. Our designers have designed a brand new frame that is easy to step over.
This 100% aluminium CGF (Comfort Geometry Frame) frame is both comfortable and easy to handle. The inclination has been studied to keep your back straighter while the rear chainstays are shortened to ensure good agility of the bike in turns.

27.5" WHEELS & TYRES FOR DRY TERRAIN
The wheels of the ST 100 are tolerant and sturdy, with 27.5" double-walled rims with 28 spokes. Slow down without worrying about obstacles: small rocks, cracks, holes and bumps! Because you're getting started with MTB touring on dry ground, this mountain bike is equipped with DRY 27.5 x 2.0 tyres. Their performance is optimized thanks to a very rolling central part, while their side studs provide good grip in turns.
V-BRAKES WITH PADS
Two V-Brake pads for effective braking.These brakes are composed of callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels.
Thanks to the special design of the ST 100's aluminium brake levers, you only need two fingers to brake.
Once a year, check how the pads are wearing. If the grooves are disappearing, take your bike to your local store's workshop.

Saddle
The saddle of the ST 100 is welded to prevent any movement of the saddle.
And because your comfort is our priority after your safety, we've added an exclusive wider Ergofit saddle with a hammock shape.
Easily adjust the height of your saddle with the Flex steel seat post, either 350 mm or 400 mm long (according to the bike size). Its reduced diameter of 27.2 mm provides your seat with natural flexibility, 30% more than a standard solution.

TRANSPORT and STORAGE
We added a quick release system for easily attaching/removing the front wheel.
There is a nut at the back to secure the bike and limit the risk of theft. You will need a spanner to remove the rear wheel.
Our advice: a bike carrier is a simple way to transport your mountain bike easily, without dirtying your car.
