Very good

For the price I'm impressed with what this bike comes with. You're talking close to £3k a branded bike with similar spec. It doesnt seem like they have put very low spec parts on either. For an entry level full suspension bike look not further than this. It's super smooth on very rough terrain, very responsive and light. I have added a seat dropper, which is essential in my opinion. Only reason it's not 5 stars is because: 1) The gears were very poorly set up when I received it. My first ride was cut short by terrible indexing. I have since tuned them myself and they are now spot on, very slick gear shifts, just disappointed Decathlon couldnt provide it like that 2) The tyres come with all the bits to go tubeless, however, it was an absolute pain to do. The tyres are ridiculously porous and the rear rim needed a burr filing from the seem before the tyre would seal properly. I've nearly managed to sort it after copious amounts of sealant and lots of shaking of the wheel, but they still lose a bit of air. Hoping this will get better the more I ride. Time will tell how rugged this bike is, but other than the above niggles I'm very pleased so far.

ROCKRIDER 900s Xc 29er UK

I have always liked my cross country bikes .i have been a specialized epic fan. ...BUT this bike ticked all boxes . The guys from Southampton decathlon got it from France for me and I am very glad they did £1699 .. amazing value . V light Xc bike with 120mm travel .. it can lock out from handle bars .. i am very very pleased with this bike . It literally takes off ., soaks up the bumps and stops.. very fun seriously good value

A ace XC bike

I had this ace bike for 3 months now and wow I have to say its a bargain. Was looking at Scott Sparks and Ordea Oiz but to get a carbon frame we was looking at almost double the amount.. So pleased I went with the wildcard as when I picked it up it was very pleased as it is a great looking bike. First outings some some setting up shocks and tyre pressure etr and we was all good. This bike just goes has great turn of speed and was finding on the trails I had to start turning into corners sooner. 1 by 12 speed is ace you have all the gears you need. My other bike is 1 by 10 so nice to have those etr low gears when it gets really steep.. Tyres are fast and yes they do lack grip when it gets more muddy but then again tyres are a very personal thing so change to what you like. Like that you can lock out front and rear shock at same time and works well. All in all a great bike and look forward to putting more miles on it in spring and summer this year and racing it at exposure 2412 in July should make the 24hr solo race more fun on the downs and ups.

Calidad precio de las mejores de mercado

Llevo más de 6 meses con esta bici y calidad precio no tiene nada que envidiar a las de gama alta es más ojalá sigan así porque se quiere comprando una bici cómo está

Muy buena elección

Lo primero es la relación calidad-precio que es demoledora respeto a otras marcas. Vista en directo diría que es más bonita que en las fotos. Va muy bien rodando, sube bien (un poco más perezosa que una rígida, como todas las dobles) y da mucha seguridad bajando, te lo hace todo más fácil. El servicio en la tienda, en mi caso Albacete para la entrega y los primeros ajustes, de lujo. Como punto débil que tiene fácil solución: Los neumáticos, aconsejo cambiarlos porqué son ligeros y bonitos, pero su uso con seguridad está restringido a terreno muy seco y muy compacto. Por lo demás, es una bici muy equilibrada.

CABLEADO

Esta bicicleta está bastante bien, pero solo le falta que los cables vayan por el interior del cuadro, entonces sí sería una señora MTB...

Xc900s

E cambiado de xc100s a xc900s y estoy súper encantado e mejorado hacia arriba y hacia abajo y sobre todo la seguridad que me da al bajar me la aconsejo peris y menos mal que le hice caso estoy encantado!!!!!!!

Mi estreno en la doble

En mis dos salidas con ella ,no tuve ningun problema es mas estoy super encantado ,me dijeron cinco dias y es lo que me tardo en llegar,y en la tienda del poligono de roces,gijon ,me hicieron el ajuste perfecto son muy buenos profesionales,la recomiendo,un saludo

Demasiados problemas

La bici tiene 6 meses y se ha pasado 2 en el taller y sigue sin ir bien. Ha ido dos veces al service center. Además han sustituido piezas que funcionaban bien y no han reparado los problemas. *Falla el combolock, sigo sin poder hacer uso de la posición intermedia de la horquilla. Parece que no hay nadie que sepa ajustarlo. *Se afloja algo en las ruedas y hace que el cassette tenga juego. *El cableado es excesivamente largo y afea muchola bici.

Hola ,
Te puedes pasar por una de nuestras tienda para que te podamos solucionar los problemas que nos comentas , el unico inconveniente es el tiempo que te pueda tardar la reparacion , ( como en cualquier otro taller )
Sentimos las molestias ocasionadas con estos desajustes

Bicicleta increible

El plazo de entrega de 5 días que muestra la web no es correcto. La bicicleta a pesar de decirme que la tenían en los almacenes de España, no es cierto. La mandan desde Francia a los almacenes de España, y estos a tu casa, con lo cual tienes que esperar unos 10 días mínimo para recibirla. Me llego con el fondo de llanta mal en la rueda delantera, y al tubelizarla me perdia aire. Tuve que llevar la rueda a mi tienda habitual y está mandarla al taller de Madrid, así que otros 5 dias mas sin poder montar. Me tocó volver a llevarla a mi tienda habitual, ya que los cambios no estaban ajustados y el soporte para el GPS Garmin se salía. Una vez solucionado todo esto he podido probar la bici en 2 rutas y he de decir que la bicicleta es espectacular. Tanto en pistas por el sur de Madrid, como en la sierra con bajadas y subidas. La doble amortiguación en las bajadas hace que la bici se sienta muy segura y se agarre genial al terreno. Una vez que colocas el SAG de ambas suspensiones a tu peso, es genial tanto para subidas como para bajadas. Los cambios muy bien, van muy finos. El sistema Combolock es genial y super cómodo de usar. El manillar de 720mm es ideal para manejarla. Si tuviera que ponerle alguna pega a la bicicleta es la escasa documentación que trae, no viene manual de instrucciones ni de montaje. Así que tuve que buscar por internet cómo ajustar ambos amortiguadores y los SAG a mi peso. Hasta el momento solo he podido hacer 2 salidas de unos 50Km cada una, en cuanto la haga más kilómetros os cuento más detalles de mi experiencia, que hasta el momento es genial

Bicicleta perfecta pero vino mal ensablada

La bicicleta está perfecta, la mejor calidad precio del mercado sus componentes top, pero vino mal ensamblada, los disco pegan con las pastillas, la transmisión salta los cambios y los ejes de la llantas demasiado duro para quitar.

Buena mtb

Cumple de sobra las necesidades de la inmensa mayoría de gente que quiera prácticar MTB. Muy buena relación precio/calidad

Muy buena compra

La bici es muy bonita , estoy tan contento que no se que poner , solo puedo decir que desde que le tengo estoy todo los dias de ruta aunque este cansado salgo igual jajaja es una pasada rapida,comoda,agil, y muy bonita , esta bici esta ella para disfrutar . Igual por intentar mejorar algo seria los frenos , porque ami me gusta mucho apurar las frenadas pero la bici frena muy bien y para la uso que le doy tengo frenos de sobra Un saludo

Rockrider XC900S es una máquina muy bien diseñada

Hola, ya escribí una opinion a bote pronto, recien comprada la bici, hablando de las maravillas de esta maquina. Ahora, 6 meses después, con ruedas Specialized Groundcontrol 2,30 delante 2,10 detrás. Presiones equiibradas y suspensiones ajustadas a mi peso, estoy euforico con el rendimiento de la bicicleta. Subiendo, pero sobretodo bajando.Solemos hacer bastante sendero y trialera. Es increible la seguridad, la velocidad que consigues en tramos extremos.Todos mis compañeros alucinan, parece una Stumpjumper Specialized. Estoy realmente contento con la bici. Totalmente recomendable su compra. No hace falta marcas de elite

Muy bien la bici, mal servicio post venta

La bici llegó con el tensor de la suspensión delantera en mal estado, y no me la pueden reparar en la tienda por que dicen que no les envían la pieza y tienen que mandarla al taller de león, quedándome sin la bici un mínimo de 15 días. Es una cosa que no veo muy normal siendo la bici nueva y habiendo venido la bici ya con el problema.

Hola Sentimos mucho los problemas ocasionados con nuestra bicicleta . Acérquese alguna de nuestras tiendas DECATHLON para que un vendedor técnico pueda valorar los daños  para poder dar la mejor solución . Gracias por confiar en nuestros productos , esperamos que vuelva a disfrutar de él con toda normalidad . Atentamente para cualquier otra consulta .
