View the B’Twin Rockrider 27.5″ ST 530 S Alloy Full Suspension Mountain Bike

Not only do Rockrider produce a range of exceptional value hardtails, but for not much extra they've managed to produce a handful of full suspension models too.

Here we have the Rockrider ST 530 S, their cheapest full suspension model at £500, featuring a 6061 alloy single pivot frame fitted with an adjustable Rockrider U-Fit 120mm coil shock.

Up front you'll find an own brand matching travel suspension fork, again with the U-fit rider weight based adjustability.

Tektro supply the hydraulic disc brakes, stopping the 27.5" own brand wheelset, and the bike is powered by a Microshift Advent 1x9 speed groupset.

The whole mountain bike weighs a shade under 34lbs (15.4kg), with the frame alone weighing an impressive 2.7kg (5.95lbs) without the shock - so definitely something you can build on, should you wish to upgrade for lighter components at a later date.

This is a lot of trail bike for the money - by producing their own frames and forks, Rockrider have impressively managed to keep the price under £500 for a perfectly rideable full suspension MTB.

In terms of specification, the 530 S is essentially the same bike as the popular ST 530, just with a full suspension frame and increased travel, instead of a rigid hardtail frame.

The next model up is the ST 540 S, costing approximately £100 more, which buys you a 2x9 Shimano groupset and saves you 1kg in weight.

Further up the range is the ST 900 S, saving yet another kg in weight with a double butted frame, X-Fusion and Rockshox air shocks and an 11 speed Shimano groupset.

B'Twin Rockrider ST 530 S Mountain Bike

This 27.5" MTB is designed for mountain bike rides lasting 2 to 3 hours, any time of year.

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.

Cycling comfort: Enjoy the raised position, adjustable stem, 120 mm suspension and hammock saddle.

Ease of use: Change gears effortlessly: 9-speed single chainring drivetrain.

Directional control: Control your trajectory: hydraulic fork and brakes, tyres and a wide handlebar.

Efficiency: Smooth riding: lightweight aluminium frame, single chainring, 27.5" wheels.

CHOOSING YOUR MTB SIZE: Several sizes available:.

S: 1.50m to 1.64m.

M: 1.65m to 1.74m.

L: 1.75m to 1.84m.

XL: 1.85m to 2.00m. If you are on the cusp between 2 sizes:.

Choose the smaller size for easier steering (easier to handle) and comfort (straighter back). Choose the larger size for more powerful pedalling with a more stretched-out position (more suited to performance).

UNISEX FRAME: The ST 530 S MTB has a UNISEX frame.

The frame of the ST 530 S has been carefully designed down to the smallest detail, from the top tube's relatively pronounced slope, to the wide range of sizes (M: 1.65m to XL: 2 m). 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 pedalling, the Rockrider ST 530 S frame is made from 6061 aluminium (only 2.7 kg in sizem 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 & DRIVETRAIN: A SINGLE CHAINRING, JUST LIKE THE PROS!: Enjoy the ease and efficiency of a single chainring. 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 effortlessly! ROCKRIDER FC ATB 500 32-tooth single chainring. MICROSHIFT ADVENT rear derailleur with long cage. MICROSHIFT ADVENT right shifter.

MICROSHIFT H092 9-speed cassette (11-42 teeth).

KMC Z9 wide, sturdy chain HANDLEBAR, STEM, GRIPS: The adjustable stem on the ST 530 S allows you to position the levers so they're easy to grip.

The all-aluminium ROCKRIDER stem is 70 mm (size S), 80 mm (size M/L), or 90 mm (size XL) and can be raised in 5 adjustment intervals: + 0 mm, + 7.5 mm, + 15 mm, + 22.5 mm, + 30 mm.

In detail:. 720 mm oversize ROCKRIDER SPORT aluminium handlebar.

ROCKRIDER SPORT "soft touch" 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 Rockrider by Tektro 160 mm double hydraulic disc brakes will come through for you, even in the mud.

Hydraulic brakes deliver more powerful and progressive braking and require less effort applied to the brake levers. The aluminium brake levers are light, easy to grip, and precise.

27.5" WHEELS WITH DOUBLE-WALLED RIMS AND ALL-CONDITION TYRES : The aluminium wheels are effective and sturdy: 27.5" diameter and double-walled rims.

Their diameter is the perfect balance of comfort and performance. With 28 spokes, they are lightweight, stiff, and durable. The wide, exclusive ROCKRIDER ALL CONDITIONS (30 TPI) 27.5" x 2.0 tyres have side knobs designed for riding on all types of terrain (dry, wet, etc.).

Tubeless Ready 23 mm rims: you will need rim tape, Schrader valves, and puncture sealant.

PLATFORM PEDALS: The ST 530 S comes with Rockrider Flat platform pedals with a wider surface and more pronounced dots to better keep your foot on pedal.

TRANSPORT AND STORE YOUR MOUNTAIN BIKE EASILY: We added a quick release system for easily removing/reattaching the front wheel.

Tip: a bike rack is an easy way to transport your mountain bike without dirtying your car.

ACCESSORIES: Your ST 530 S mountain bike comes with a bell, lights, wheel reflectors, and pedals.

XL - 185-200cm : 15.7 kg... more details.

B'Twin Bikes

B'Twin Bikes

B'Twin are a popular choice of bike in the UK, partly due to their widespread distribution by Decathlon, and partly due to the value they offer. Their bikes are divided into several slightly overlapping ranges, with Triban best known for road and gravel bikes, and Rockrider gaining a reputation for high performing MTBs to suit every budget. Elops largely consist of a range of city bikes, whereas Riverside focus on hybrids. All in all, B'Twin bikes are well worth checking out given the size of their ranges; there's a model to suit most budgets.

Rockrider Mountain Bikes

Rockrider Mountain Bikes

Rockrider are Decathlon's off-road offerings, comprising of a series of kids bikes and adult hardtails, full suspension steeds and even a handful of high end E-MTBs.

This brand was launched in 2018, when Decathlon decided to split their B'Twin bikes into different genres. In terms of prices, there's something for everyone, with adult's MTBs starting at just over £200 and rising up to high end lightweight race bikes at nearly the £4000 mark.

If you want to ride off-road, and would prefer to buy from Decathlon, then the Rockrider mountain bike range is for you.
