This 27.5" mountain bike is designed for getting started with MTB touring in dry weather, for rides up to 1.5 hours.
Weight: 15.5 kg in size M (without pedals) Frame material: Aluminium Type: Hardtail Wheel size: 27.5" Fork travel: 80 mm Drive train: 3X7 Brakes: V-brake with pads Seat post: Fixed Lifetime warranty on frame/2 years for parts
S: 15.4 kg M: 15,5 kg L: 15.6 kg XL: 15.8 kg
With a very marked top tube inclination, over a very wide range of sizes (from S: 1m55 to XL: 2m00 ), the frame of the EXPL 50 mountain bike is MIXED.
It isn't always easy to get the right position on a mountain bike. Our designers created a frame that's easy to get onto. The 100% aluminium CGF frame (Comfort Geometry Frame) is both comfortable and easy to handle. The slope angle has been designed to keep your back straight, while the rear bases were shortened to make the bike very agile in turns.
3 x 7 speed chainrings, 21 speeds total! 2 easy-to-use grip shifters on the handlebars. Left (chainrings): control ascents/descents. Right (speeds): more precise control over your pedalling. Details: -Triple-chainring chainset (22/32/42 teeth) + protection / grease. -Microshift FD-M20 front derailleur -Microshift RD-M25 rear derailleur -Microshift MS25 grip shifters with speed indicators -Shimano TZ500 7 cog cassette, 14 to 28 teeth -Large, solid KMC Z51 chain
The 80 mm front suspension allows you to overcome your first obstacles with peace of mind on slightly uneven trails. Its mechanical spring is a stamp of reliability. And the fork is particularly easy to maintain.
The wheels of the ST 100 are tolerant and sturdy, with 27.5" double-walled rims with 28 spokes. Slow down without worrying about obstacles: small rocks, cracks, holes and bumps! Because you're getting started with MTB touring on dry ground, this mountain bike is equipped with DRY 27.5 x 2.0 tyres. Their performance is optimized thanks to a very rolling central part, while their side studs provide good grip in turns.
Two V-Brake pads for effective braking.These brakes are composed of callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels. Thanks to the special design of the ST 100's aluminium brake levers, you only need two fingers to brake. Once a year, check how the pads are wearing. If the grooves are disappearing, take your bike to your local store's workshop.
With a stem that tilts 10° upwards, the riding position of the ST 100 is raised, accessible, and comfortable. In detail: -Aluminium stem, 90 mm long, with a 10° angle for maximum comfort.-620 mm wide steel handlebar, for stability and control. -Grips in "soft touch" material' for good grip and a soft comfortable feel.
The saddle of the ST 100 is welded to prevent any movement of the saddle. And because your comfort is our priority after your safety, we've added an exclusive wider Ergofit saddle with a hammock shape. Easily adjust the height of your saddle with the Flex steel seat post, either 350 mm or 400 mm long (according to the bike size). Its reduced diameter of 27.2 mm provides your seat with natural flexibility, 30% more than a standard solution.
The Rockrider ST 100 mountain bike is supplied with hard resin platform mountain bike pedals for added lightness and safety. If your foot slips off the pedal, you will be less likely to injure yourself.
We added a quick release system for easily attaching/removing the front wheel. There is a nut at the back to secure the bike and limit the risk of theft. You will need a spanner to remove the rear wheel. Our advice: a bike carrier is a simple way to transport your mountain bike easily, without dirtying your car.
Your ST 100 mountain bike comes with a chainring guard (to protect your clothing from dirt), bell, lights, wheel reflectors and pedals. The frame is compatible with: -500 chainstay stand (ref. 8302792) -100 bottle cage (ref. 8049106) and 500 bottle cage (ref. 8358133) -Mountain bike mudguard set (ref. 8385291) -100 saddle bag (ref. 8347394) and 500 saddle bag (ref. 8354448) -500 pannier rack (ref. 8364376) -Polisport GROOVY frame-mounted baby seat (ref.8385622), from size S
Your bike's equipment (chain, derailleur, brakes, etc.) will adjust. Take advantage of the free revision within 6 months of purchase. Our technicians will carry out a 13-point inspection of your bike. Go to the nearest DECATHLON workshop with your DECATHLON card and/or receipt.
Several sizes available: S: between 1.55m and 1.64m M: between 1.65m and 1.74m L: between 1.75m and 1.84m XL: between 1.85 m and 2.00 m To adapt the bike to your height and size, try these tips: 1/ Sitting on the saddle, you should be able to touch the ground with the tips of your toes. 2/ To adjust the saddle, your knee will be slightly bent with your foot on the pedal in the low position. 3/ If you hesitate between two sizes, choose the larger size.
