    亲爱的顾客 您好!

    感谢您购买迪卡侬山地自行车
    您购买的是迪卡侬入门款山地自行车,刹车为V刹,异响来源可能是刹车皮与轮圈未调至水平导致共振,但是不影响刹车效果,也有可能是刹车皮或轮圈沾染异物导致,具体建议您前往迪卡侬客服工作室进行检查

    Additional Product Information

    This rockrider st100 has a history

    Entirely designed and developed in France at the B'Twin Village (Lille), this mountain bike is the fruit of the work of an expert team of passionate mountain bikers.To best meet the need for comfort and ease expressed by beginner mountain bikers, the team created, designed, and tested the ST100, involving riders at every stage of the project.Whether you're heading out alone, with friends or family, the fun of riding the ST100 mountain bike has been fully approved by users!

    A unisex mountain bike

    The ST100 mountain bike is suitable for both men and women.Carefully designed down to the smallest detail, with a noticeable slope on the top tube, with a wide range of sizes (XS: 1.45m to XL: 2.00m), the CGF frame of the ST100 is light, comfortable, and very versatile.To make the most of the improved comfort, the women of the Rockrider team recommend the 500 Women's Sport saddle that is adapted to women's morphology.

    How do you choose the right st100 mountain bike size?

    Several sizes available:XS: between 1.45m and 1.54mS: between 1.55m and 1.64mM: between 1.65m and 1.74mL: between 1.75m and 1.84mXL: between 1.85m and 2.00m

    A light, comfortable, fun frame

    Because we've noticed that it's not always easy to get the right position on a mountain bike, our designers have created an entirely new frame that's easy to get onto for both men and women.The CGF frame (Comfort Geometry Frame) is 100% aluminium for optimal comfort and excellent manoeuvrability. The slope angle has been designed to keep your back straight whilst the low rear ensures the bike is very agile when turning.

    Front suspension for cushioning lumps and bumps

    The SUNTOUR XCT 80mm front suspension is designed for slightly uneven trails and helps you overcome your first obstacles with no worries.Its design, based on a mechanical spring, is reliable and easy to maintain. You can also easily adjust the stiffness using a dial.

    Rear suspension: none

    This mountain bike has no rear suspension. This is a "semi-rigid" mountain bike:ideal for starting out.Compared to a full suspension mountain bike (with rear suspension), the advantages are very simple:considerably light and less energy wasted on flat terrain.A semi-rigid mountain bike like the ST100 is the perfect choice for your first outings!

    Derailleur & drive train: change chainring and cog

    3 x 7 speed chainwheels, 21 speeds total!2 easy-to-use grip shifters on the handlebars.Left (chainwheels): control ascents/descents.Right (speeds): more precise control over your pedalling.Details: -Triple-chainwheel chainset (22/32/42 teeth)+ anti-grease protection.-Front Microshift FD-M20 derailleur-Rear Microshift RD-M25 derailleur-Microshift MS25 grip shifters with speed indicators-7 cogs, 14 to 28 teeth Shimano TZ21 cassette-Large, solid KMC Z51 chain

    Stem, handlebar, grips: for good hand positioning

    With the 10° angled stem, the ST100 offers a higher steering position that is accessible and comfortable.In detail:-Aluminium stem, 90mm long, with a 10° angle for maximum comfort.-600mm wide steel handlebars for stability and control.-Grips in soft touch material for good grip and a soft comfortable feel

    Saddle: sit comfortably!

    The saddle fixing (welded) of the ST100 prevents any movement of the saddle as you cycle.Because your comfort is our next priority after safety, we've added the exclusive Ergofit saddle that's wider and with a hammock shape.Easily adjust the height of your saddle with the Flex steel seat post, either 350mm or 400mm long (according to the bike size).Its reduced diameter of 27.2mm provides your seat with natural flexibility, 30% more than a standard solution.

    V-brakes: control your braking

    Brake effectively thanks to the V-brake brake pads.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 ST100 aluminium brake levers, only two fingers are needed to brake.

    27.5" wheels & tyres for dry terrain: ready to roll?

    Slow down without worrying about obstacles: small rocks, cracks, holes and bumps!The wheels of the ST100 are tolerant and robust, with 27.5-inch double-walled 28-spoke rims (26-inch single-wall 32-spoke on the XS size).Because your first tours will be on dry ground, the Dry 27.5 x 2.0 tyres are most suitable. Their performance is optimised thanks to the rounded central section, whilst the side lugs provide good grip on turns.

    Flat pedals

    The Rockrider ST100 mountain bike will be supplied with resin platform mountain bike pedals for added lightness and safety.If your foot slides on the pedal, there's less risk of injury.

    Easily transport and store your mountain bike

    At ROCKRIDER, we know that not all rides start on your doorstep or right outside the store. You might need to transport or store your bike in a confined space (car boot, porch, etc.). To make it easier to mount / remove your front wheel, we've fitted it with a quick release system.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 back wheel.

    Weight

    15.3 kg in size XS without pedals.15.4 kg in S without pedals.15.5kg in M without pedals.15.6 kg in L without pedals.15.8 kg in XL without pedals.

    Accessories

    Your ST100 mountain bike is delivered with a derailleur guard, chainwheel guard (to prevent your clothes becoming dirty), bell, lights, wheel reflectors and pedals.The frame is compatible with:-Front and rear mudguards (Flash MTB or MTB 900)-Stand (500 Adult Base)-Bottle cage-Saddle pouch-Rear pannier rack-Child seat (Polisport Groovy frame mounted)

    Comfort & safety

    We recommend that beginners wear cycling shorts with a pad (foam in the shape of a saddle) or a gel saddle cover to reduce soreness.For longer rides, remember to take something to drink (e.g. a water bladder or bottle).In all circumstances, even for a short ride, wearing a helmet is essential!
