Very good

It exceeded my expectations, how good

Excellent bike. Report…

Excellent bike. Undeniable value for money. It’s a shame that the SRAM level T handlebars and brakes don’t live up to the bike’s ambitions.

Race 900s gx

I bought the Race 900s gx bike from the Braga store. Overall, I'm super happy with the bike, good frame, good gx transmission, good suspension... only the brakes are mediocre, very good price, quality, I recommend it... I want to congratulate the employees who helped me impeccable service José Lima, Pedro, another colleague, sorry I don't remember his name at the moment..

Very good bike

super bike

Great bike! top The only problem I saw was that for a bike like this, it had to come with a tubeless VALVE kit. I thought it came with the valve kit! and he didn't come.

good bike

very good bike on the other hand late delivery also upon receipt the bike was damaged at the fork traces of friction (maybe due to transport) I asked for a bottle holder in return that the sellers who welcomed me wanted me offer but their superior refused. thank you decathlon villars!!!!!!!! I'm a very good customer though, I'm not congratulating you on that one, especially the department manager that day.

XV 900 mountain bike

Great bike, great value for money


Bought on offer in the gx axs version with Reynolds wheels. tested 4 outputs. upgrade from an all mountain aluminum am100s. new brakes and discs changed. I recommend it for the xc, it's light, the acceleration is very good, the transmission as well. double suspension useful for the column. for the money paid, it is the best new bike option. I have not yet tested it on difficult routes (downhills, trails, etc.)

not yet ridden with it but....

I have just purchased the full carbon bike without an electric pack and I find it a shame that the derailleur cable does not pass directly through the frame of the mountain bike on a white mountain bike like that at this price, it looks very ugly knowing that in the video it does not does not appear and it is much more aesthetic, moreover in this case it would be good to put a plastic cover on top like a Rockrider 540 series because when I received mine I was very disappointed to see this very ugly cable I preferred to keep the mountain bike because I cannot afford an electric derailleur and my technician had prepared it tubeless, changed the stem etc and I thank him for not mentioning it Thomas ( said TOTO) In Dieppe and Allan 2 great guys on the shelves. Well, more than tested this weekend we'll see what happens next....

happy discovery

After having cut my teeth on an XC 120, a very good bike whose limits I had reached, I wanted to move upmarket, affected by the XC virus. The trade-in of my old bike by Decathlon allowed me to treat myself to this XC 900S which I had wanted for a long time. My first pedal rides convinced me! It is light (thanks Carbone), very easy to handle, quite nervous on the climbs, and stony descents now go smoothly. The 120mm fork and the rear shock absorber have a lot to do with it. The 52 cassette allows you to climb fairly steep hills provided you have the legs and the brakes do the job in normal conditions. Despite the -7° stem, the position remains comfortable. I added the telescopic saddle (essential accessory) and switched the tires to tubeless to avoid repeated punctures on our shale trails. Well done to the Decat workshops in Béziers who prepared the bike perfectly for me, giving me good advice in advance. Professional work, nothing to complain about! Only downside on this bike: the mess of cables in front of the handlebars (7 in total!) and the original pedals, a bit kitsch for this range (that's changing...) All I have to do is try it out on more technical trails but for the moment, I'm already amazed. At that price, it's great stuff!
