Suspension
-
Fork
This mountain bike has an adjustable fork for clearing obstacles (roots, rocks, stones...) with peace of mind thanks to its 80 mm travel.
Drivetrain
-
Crankset
This bike is equipped with speed control levers that are controlled using the thumb and index finger, allowing effortless changes between the 9 speeds. The chainset has 152 mm cranks and is equipped with a double chainguard to prevent derailment. The 32-tooth single chainring and 11-36 cassette make it easy to change gears. They allow you to tackle gradients with a single control. So you can stay focused on steering.
Brakes
-
Brakes
A bedding-in process is required. On a flat, dry road, perform 3 sets of 10 progressive brake applications at increasing speeds. 1) Ride at 15 km/h, brake down to 5 km/h, and repeat 10 times. 2) Ride at 20 km/h, brake down to 5 km/h, and repeat 10 times.3) Optional (kid's bike): Ride at 25 km/h, brake down to 5 km/h, and repeat 10 times.Between each step, release and ride for a few dozen metres in order to ventilate the disc.This bedding-in process optimises the pad/disc adhesion.
Wheels and tires
-
Rims
The double-walled aluminium rims are light and resistant. To transport your bike, we've made it easier to remove/install the front and rear wheels with a quick release system. The wide 26"x2.2 Skinwall tyres provide good traction and comfort. The 26" inner tube is compatible with tyre cross-sections of 1.7 to 2.2 with Schrader valves. The tyre pressure is shown on the sidewall (between 2 and 3.5 bars).Tubeless ready rims.
