TECHNICAL INFORMATION

A frame for off-road cycling:

Our engineers have designed a new aluminum frame. Strong, light and dynamic, it's ideal for overcoming all obstacles on your mountain bike outings.

Powerful braking :

Brake smoothly and powerfully with front and rear hydraulic disc brakes.

Running-in disc brakes :

Running-in is necessary. On a flat, dry road, perform 3 series of 10 progressive braking operations at increasing speeds.

1) Ride at 15 km/h, brake down to 5 km/h, repeat 10 times.
2) Ride at 20 km/h, brake down to 5 km/h, repeat 10 times.
3) Optional (child's bike): Ride at 25 km/h, brake down to 5 km/h, repeat 10 times.

Between each step, release the brake and ride for a few dozen meters to ventilate the disc. This run-in optimizes pad/disc adhesion.

A 9-speed single-plate transmission:

This bike is equipped with a trigger-operated shifter for quick shifting of the 9 gears.
The crankset has 152mm cranks and is fitted with a double housing to prevent derailment. The 32-tooth single chainring and 11-36 cassette facilitate gear shifting. They make it possible to overcome the course's unevenness with just one control to manage. You stay focused on riding.

Front suspension to cushion the terrain:

This mountain bike is equipped with an adjustable fork to overcome obstacles (roots, pebbles, stones, etc.) serenely thanks to the 80 mm travel.

A child-friendly saddle:

A saddle with a sporty design, designed by us and adapted to children's morphology. Combined with a sturdy, flexible aluminum seatpost, it provides comfort.

A precise cockpit:

To refine your riding, we've fitted this mountain bike with a short (60mm) aluminum stem and 620 mm "Oversize" handlebars. You'll be more precise and livelier when you turn.

Aluminum crankset:

The new aluminum crankset has a crank length of 152 mm which is adapted to the child's leg length. This lightweight crankset makes it easier to start pedaling.
The double chain guard prevents chain derailment.

Double-walled rims:

The double-walled aluminum wheels are strong and lightweight.
To make transporting the bike easier, we've fitted the front and rear wheels with a quick-release system.
The wide 26 "x2.2 Skiwall tires provide good grip and comfort.
The 26" inner tube is compatible with tires with cross-sections from 1.7 to 2.2, schrader valve. Inflation pressure is indicated on the tire sidewall (between 2 and 3.5 bar).

Bicycle equipment is available:

As required by law, this mountain bike is equipped with a bell, lights, wheel reflectors (reflectors) and flat pedals.

The frame is also compatible with other accessories:
- front and rear mudguards
- water bottle holder
- speedometer
- saddle bag / handlebar bag / frame bag
