Enjoy the comfort of the 120 mm front and rear suspension on the ST 530 S. The single chainring and the hydraulic disc brakes are your best allies for adapting to changing terrain as you ride.
This 27.5″ MTB is designed for MTB rides lasting 2 to 3 hours, all year round.
Which is the right size?
Several sizes available:
S: between 4’11” and 5’5″
M: between 5’5″ and 5’9″
L: between 5’9″ and 6′
XL: between 6’1″ and 6’7″
If you are at the limit between 2 sizes:
Choose the smaller size for easier steering (easier to handle) and comfort (straighter back).
Choose the larger size for easier pedaling with a more stretched-out position (position more suited to performance).
UNISEX FRAME
The ST 530 S MTB has a UNISEX frame.
The ST 530’s frame has been carefully designed down to the smallest detail, from the top tube’s relatively pronounced slope, to the wide range of sizes (M: 5’5″ to XL: 6’7″). The ST 530 S is not only lightweight and comfortable, but UNISEX as well.
To make the most of the improved comfort, the women on the RockRider team recommend the 500 Women’s Sports saddle, which is specially designed for the female form.
A WORD FROM THE TEAM
The ST 530 S mountain bike was fully designed and developed by our passionate MTB team at the B’Twin Village in France (Lille).
A mountain bike that makes steering easier: more powerful and progressive hydraulic disc brakes, shocks, and a fork with 120 mm travel for riding over obstacles, a single chainring so you can very quickly adapt to changes in terrain, etc. MTB riders were involved at every stage of this bike’s creation to make sure it works just right.
A LIGHT, COMFORTABLE FRAME
For less weight and more efficient pedaling, the RockRider ST 530 S frame is made from 6061 aluminum (only 6 lbs in size M without suspension). Its 120 mm rear shock uses a single-pivot system (more sensitive to small impacts, while remaining firm when encountering large impacts) and sealed bearings for a great lifespan.
120 MM FRONT SUSPENSION
The hydraulic fork, with 120 mm travel, allows you to easily ride over more obstacles (roots, pebbles, stones, mud).
The fork’s built-in lockout system helps to prevent bobbing and loss of speed on faster terrain.
Rear suspension
This mountain bike has a RockRider U-Fit 120 mm spring shock absorber, specially adjusted for this frame. You can easily adjust it based on your weight, which provides you with a very good balance between sensitivity and performance.
DERAILLEUR AND DRIVETRAIN: A SINGLE CHAINRING LIKE THE PROS!
The single chainring is easy and efficient to use:
1 chainring and 9 speeds.
Accelerate on the flats and easily tackle the climbs.
With a single lever on the handlebar, you can change gears while hardly thinking!
-ROCKRIDER FC ATB 500 single chainring (32T)
-MICROSHIFT ADVENT rear derailleur with medium cage
-MICROSHIFT ADVENT right shifter
-MICROSHIFT H092 9-cog cassette (11-42 T)
-KMC Z9 wide, sturdy chain
HANDLEBARS, STEM, GRIPS
The adjustable stem brings the ST 530 S controls to your hands. The all-aluminum ROCKRIDER stem is 70 mm (size S), 80 mm (size M/L), or 90 mm (size XL) and can be raised to 5 adjustment intervals: + 0 mm, + 7.5 mm, + 15 mm, + 22.5 mm, + 30 mm.
In detail:
– 720 mm oversize ROCKRIDER SPORT aluminum handlebar
– ROCKRIDER ergonomic grips for good grip and a comfortable feel.
Saddle
The ST 530 S saddle is welded to prevent any saddle movement as you cycle.
Because your comfort is our next priority after safety, we’ve added an exclusive RockRider Ergofit Evo saddle that is wider and hammock shaped.
Easily adjust the height of your saddle with the 400 mm long, 31.4 mm diameter seat post.
HYDRAULIC DISC BRAKES
No matter what conditions you ride in (dry/wet), the SHIMANO MT200 160 mm dual hydraulic disc brakes will come through for you, even in the mud.
Hydraulic braking adds more power and progressive braking and requires less powerful use of the brake levers.
The aluminum brake levers are easy to grip and precise.
27.5″ WHEELS WITH DOUBLE-WALLED RIMS AND ALL-CONDITION TIRES
The aluminum wheels are effective and sturdy: 27.5″ diameter and double-walled rims. Their diameter is the perfect balance of comfort and performance. With their 28 spokes, they are lightweight, stiff, and durable.
The wide, ROCKRIDER ALL CONDITIONS (30 TPI) 27.5″ x 2.0 tires have side knobs designed for riding on all types of terrain (dry, wet, etc.).
Tubeless Ready 23 mm rims: SCHRADER valves, TUBELESS rim tape, TUBELESS tires, and puncture-proof liquid to be added.
Platform pedals
The ST 530 S comes with RockRider Flat platform pedals with a wider pedaling surface and more pronounced dots for better grip on the pedals.
EASILY TRANSPORT AND STORE YOUR MOUNTAIN BIKE
We added a quick release system for easily removing/reattaching the front wheel.
Our advice: A bike rack is an easy way to transport your mountain bike without dirtying your car.
