Your ST 530 S mountain bike comes with bell, lights, wheel reflectors and pedals. The frame is compatible with: -Side-opening bottle cage (ref. 8548543) -MTB mudguard kit (ref. 8385291) -100 (ref. 8347394) and 500 (ref. 8354448) saddle bags

Passionate about mountain biking, we entirely designed and developed this ST 530 S mountain bike at the BTWIN VILLAGE (Lille). A mountain bike to gain in ease of riding: more progressive and powerful hydraulic disc brakes, 120mm shock absorber and fork to overcome obstacles, single chainring to adapt very quickly to the hazards of the terrain ... Mountain bikers were involved at all stages of the project to validate this bike.

This mountain bike features a 120mm ROCKRIDER U-FIT coil shock, specifically tuned for its frame. You can easily adjust it to your weight, ensuring a very good sensitivity/performance ratio.

No matter the conditions you're riding in (dry/wet), the dual 160mm hydraulic disc brakes for the front and rear will deliver, even in the mud. Hydraulic braking gives you more power and progressiveness, as well as significantly less muscular effort to apply to the levers. The aluminum brake levers are easy to grip and precise.

With its adjustable stem, the ST 530 S's controls fall right to hand. The all-aluminum ROCKRIDER stem, measuring 70 mm (size S), 80 mm (size M/L) and 90 mm (size XL), can be raised in 5 adjustment steps: + 0 mm, + 7.5 mm, + 15 mm, + 22.5 mm, + 30 mm. In detail: - ROCKRIDER SPORT "oversize" aluminum handlebar, 720 mm wide - ROCKRIDER SPORT "soft touch" grips, for good grip and pleasant contact

For more lightness and to pedal efficiently, the frame of the ROCKRIDER ST 530 S mountain bike has been designed in 6061 aluminum (only 2.7KG in size M, without shock absorber). Its 120 mm rear shock is based on a mono-pivot system (more sensitive to small bumps in the terrain, while remaining firm in the face of big impacts) and on sealed bearings, for good longevity.

The ST 530 S mountain bike frame is MIXED. Designed down to the smallest detail, with a very pronounced sloping (an inclination of the top tube), over a fairly wide size range (from M: 1m to XL: 65m), the ST 2 S mountain bike frame is not only light and comfortable, it is also MIXED. To enjoy even greater comfort, the women of the ROCKRIDER team recommend the SPORT FEMME 00 saddle, adapted to the female morphology.

Several sizes are available: S: between 1,50 m and 1,64 m M: between 1,65 m and 1,74 m L: between 1,75 m and 1,84 m XL: between 1,85 m and 2,00 m If you are on the border between 2 sizes: Take the smaller size to favor the piloting phases (easier bike to handle) and comfort (more upright back). Take the larger size to favor the pedaling phases with a more stretched position (position more suited to performance).

The ST 530 S bike comes with ROCKRIDER FLAT flat mountain bike pedals, with a wider contact surface and more prominent studs for better foot support on the pedal.

The ST 530 S's welded saddle mount prevents the saddle from moving while riding. Because after safety, your comfort is our priority, we offer you an exclusive, wider ROCKRIDER ERGOFIT EVO saddle with a hammock-shaped profile. Easily adjust your saddle height with the 31,4 mm diameter, 400 mm long steel post.

The hydraulic fork with its 120 mm travel allows you to overcome more obstacles (roots, pebbles, stones, mud) with complete peace of mind. The locking system integrated into the fork allows you to avoid pumping effects and loss of speed on rolling sections.

The aluminum wheels are efficient and robust: a diameter of 27,5" and double-walled rims. Their diameter is an excellent compromise between comfort and performance. With 28 spokes, they are light, rigid and resistant. The wide ROCKRIDER ALL CONDITIONS (30 TPI) 27.5"x2.0 tires have side knobs for all terrain (dry, wet). 23 mm profiled TUBELESS READY rims: SCHRADER valves, TUBELESS rim strips, TUBELESS tires, and anti-puncture liquid to be added.

To easily remove/install the front or rear wheel, we've added a quick-release system. Our tip: a bike rack is a simple way to transport your mountain bike without getting your car dirty.
