    Product feature
    1. The story of the Rockrider 900 mountain bike...
      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. We have designed and tested this RR900 mountain bike for mountain bikers who want to surpass their limits and ride even faster when cross-country mountain biking.
    2. A unisex MTB
      Men's or women's mountain bike? The Rockrider 900 mountain bike is unisex. For greater comfort, the women on our mountain bike team recommend replacing the saddle with the Women's 500 Sport saddle, which is adapted to women's bodies.
    3. Choosing my MTB size
      Several sizes available: S: between 1.50m and 1.64m M: between 1.65m and 1.74m L: between 1.75m and 1.84m XL: between 1.85 m and 1.95 m If you are on the limit between 2 sizes, we recommend following the exact size listed.
    4. A frame designed to combine fun and performance
      For the RR900, our teams have specifically designed the frame in T4 & T6 6061 aluminium (only 1.8kg in size M). It has been specially designed to meet the needs of those wanting to get started with cross country riding, very demanding in terms of durability and low weight. 73 mm BSA bottom bracket Oversize diagonal tube Conical tapered head tube Available in 4 sizes: S/M/L/XL
    5. Front suspension locks/unlocks on the handlebar
      To overcome any obstacles you encounter, the Manitou M30 Air fork and its 100mm travel will always be there for you. Quickly lock and unlock the fork with the 2-position Combo Lock locking system on the handlebars. 1-1/8" aluminium conical pivot, 1.5" taper, for increased rigidity and low weight. Axle: 9 mm. Weight: 1.7 kg
    6. Rear suspension: none
      This mountain bike has no rear suspension.
    7. Derailleur & drive train: single drive train for optimal performance
      The RR900 inaugurates the new line of single-chainwheel SRAM drive trains. The SRAM NX 1x11 drive train ensures light weight, durability, precision, and better control of your mountain bike. Chainwheel size: 30 teeth, easily replaceable (up to 32 teeth) without changing the chain. SRAM PG1103 cassette with 11 cogs: 11, 13, 15 ,17, 19, 22, 25, 28, 32, 36, 42 teeth. The 42-tooth sprocket guarantees good gear reduction to help you climb the steepest sections.
    8. Handlebar, stem, grips: keep control
      Since cross country requires good control of your steering position, we equipped this mountain bike with an oversize low rise Rockrider 900 XC Series handlebar (slightly curved). Its 680 mm width guarantees good stability and optimal comfort when steering. The ROCKRIDER XC stem is adapted to each size (80mm in size M, 90mm in size L, and 100mm in size XL) Semi-integrated headset with sealed bearings. ROCKRIDER 900 light lock on grips.
    9. Saddle / Seat post: comfortable and sporty seat
      Our designers have developed the new Rockrider 900 Series saddle to be lighter (only 265 g) and more comfortable during pedalling. With a 29.8 mm diameter and 350 length, the B'Twin Comp seat post offers a wide range of adjustments and a raised riding position.
    10. Double hydraulic disc brakes: incisive braking
      The exclusive 160 mm TEKTRO TKD 32 double hydraulic disc brakes will stop you in all circumstances. With their 2 pistons, semi-organic pads, and aluminium body, they combine power and light weight, essential for cross country riding. For even more efficiency, the brake levers have been specially designed to be quickly manipulated with 2 fingers.
    11. 27.5" wheels & lightweight all-terrain tyres to withstand XC rides.
      The MAVIC CROSS RIDE FRS-X wheels made of S6000 aluminium will carry you over all terrain. Lightweight and durable, their 27.5" diameter guarantees an excellent balance between handling obstacles, comfort, and manoeuvrability. The 27.5 x 2.1 HUTCHINSON PYTHON 2 tyres are recognized in the world of cross country for their excellent performance on dry, slightly rough terrain.
    12. Platform pedals
      The bike comes ready to use with B'TWIN FLAT PRO platform pedals. However, to optimise its performance, you can replace these with clipless pedals (not included).
    13. Easily transport & store your mountain bike
      The front and rear wheels attach and remove in 1 motion: you just need a hex key (size 6). The rear derailleur has a screed that locks and unlocks easily to easily attach or remove the rear wheel.
    14. Weight
      11.8 kg in size S, without pedals. 12 kg in size M, without pedals. 12.2 kg in size L, without pedals. 12.4 kg in size XL, without pedals. The weight can vary based on the tolerance of the components. The bike comes with B'Twin Flat Pro platform pedals. The total weight (bike + rider) should not exceed 120 kg.
    15. Our advice for your first ride
      During the first few outings, your bike's components will adjust (chain, derailleur, brakes, etc.). We offer you a free service check within 6 months of the date of purchase, during which our technicians will perform a 13-point check of your bike.

      Měl jsem toto kolo půjčené na třídenní test, ale hned po první jízdě jsem si ho zamiloval. Tento na první pohled neohrabaný lenoch se umí pěkně rorvášnit když mu přiložíte do pedálů. Rozsah jednopřevodníku je ideálně nadimenzovaný jak pro terén a kopce tak rychlý městský sprint! Kolo je obrovské, lehoučké, ale díky skvělé geometrii je obratné a krásně se ovládá. Vidlice poskytuje komfortní jízdu po lese, a po zamčení vás nechá velmi rychle rozšlapat do topspeedu. Pedály jsou příjemné, za celý den nenechali botu zklouznout ani jednou. Brzdy jsou pohotové, není problém zastavit téměř na místě a i po delším brzdění v kopcích brzdí pořád stejně dobře. Jediné co mi trošku nesedlo je sedlovka, na první pohled elegantní a lehoučká, ale po zhruba 60 kilometrech v sedle (vetšinou lesní cesty a terén) jsem se modlil, ať už jsem doma! Při delší jízdě bez zastavení bylo třeba ulevit zádům a protáhnout se (Rám velikosti XL byl na mých 183cm zbytečně velký), proto obejdnám L. Tenhle Dravec je vhodný na lov kilometrů jak pro nadšence tak pro sportovce, kteří berou cyklistiku opravdu vážně!

      Celkově povedené lehké kolo. Díky převodu 1x11 je úžasně jednoduché, ale doporučuji ihned dokoupit převodník 32 zubů (sehnal jsem ho originál sram za 330Kč, běžně do 500Kč). Maximální rychlost na rovince s tímto převodem je 27Km/hod aby se člověk neušlapal. Je třeba počítat do budoucna s upgrade přehazovačky za vyšší model (NX není 100% přesný), ale mám najeto prvních 100km. Pneu rychlé a nehučí. Za tyto peníze dle mě dobrá volba. Rozhodoval jsem se mezi B-Twin 900 a Cube Attention 29.
    • Slusne XC kolo

      Dobre kolo na XC styl jizdy. Je treba pocitat s adelvatni geometrii ramu (hlava dolu, zadek nahoru). Kolo lehke, obratne a dost rychle. Jen plaste jsem menil za sirsi s vetsim zaberem v terenu. Jednoprevodnik je paradni, staci.
