    Technical Information
    Design
    The RockRider 520 was designed and created in Suzhou, China, by a team of experts and cycling enthusiasts dedicated to designing our mountain bike Sport Touring line. Production was also done near Suzhou to be as close to our Decathlon stores as possible.
    Frame
    Rockrider CGF Evo (Comfort Geometry Frame) 6061 aluminium frame for 27.5" wheels. Comfortable seating position thanks to raised steering. Seat is 5 times more flexible than a standard frame thanks to a narrow 27.2 mm seat post. Low bottom bracket: helps keep the mountain bike stable in turns, and makes it easier to place foot on the ground. Open steering angle (69.5°): keeps mountain bike stable while riding. Short rear wheel base: bike is easy to turn. LIFETIME WARRANTY on the frame!
    Front suspension
    B'Twin U-Fit 80 fork, with 80 mm of travel and an innovative fork stiffness adjustment based on the rider's weight (55 to 105 kg). Durable thanks to the materials and fabrication processes used. Equipped with a mechanical spring and elastomer stoppers for maximum reliability and minimum maintenance.
    Rear suspension
    No rear suspension.
    Drive train
    SRAM S200 triple-chainring chainset (22/32/42 teeth). SRAM X3 8-speed rear derailleur. Microshift MS22 front derailleur. SRAM X4 shifters with speed indicators. SRAM PG820 cassette, 8 cogs, 11 to 32 teeth.
    Brakes
    TEKTRO aluminium brake levers: lightweight and precise. Front and rear Hayes MX5 mechanical disc brake callipers: powerful, progressive braking, even in rainy and muddy conditions.
    Handlebar/stem/steering/grips
    B'Twin Sport Oversize aluminium handlebar; 660 mm (size S and M), and 680 mm (L and XL). Exclusive B'Twin aluminium stem, 70 mm (size S and M), and 80 mm (size L). Stem can be raised by up to 3 cm, with 5 settings (+ 0 mm, + 7.5 mm, + 15 mm, +22.5 mm, +30 mm). Semi-integrated A-headset headset—better sealed and integrated style. B'Twin Sport handles with grooves, 120 mm long: genuine comfort while riding.
    Wheels
    Aero Trail Evo wheels with double-walled rims: lightweight, stiff, and durable. 27.5" diameter: the best balance of comfort and performance. Designed with 28 spokes to reduce weight while still guaranteeing rigidity and strength.
    Tyres
    Exclusive B'Twin All Terrain Dry 27.5" x 2.0 tyres with a central tread specially designed for fast performance. Side lugs provide traction in turns. Also includes a chart showing recommended pressure levels depending on the rider's weight (see markings on tyre sidewalls).
    Saddle / seat post
    Exclusive B'Twin Ergofit Evo saddle offers outstanding comfort thanks to its wider "hammock" shape and good distribution of pressure points regardless of the rider's pelvis width. B'Twin Sport seat post in aluminium for less weight. 27.2 mm diameter provides the seat with a natural flex that's 5 times greater than a classic seat post. 400 mm long, offering a broad adjustment range.
