Great XC mountain bike at this price point.
Great mountain bike for a great price/quality ratio! You can go for it, you won't be disappointed!
I just switched from the XC 100 (used for 3 years) to this Race 900S. My world has changed to full suspension and I am very happy with my purchase. The bike is very responsive, I really like the AXS gear change. Lighter than my previous bike. As everything is carbon, Decathlon in Arlon advised me to protect the wheels with foam: Vittoria Air-Liner Light anti-perforation protection. Which they installed well with a good Tubeless setup. I had to add the K-Edge Garmin Gravity Cap, because I was used to the original mounting on the XC 100 of a Garmin socket. This protects the Garmin better during falls. This is a bike to recommend. I will use it a lot for my races and outings on varied terrain in Kenya.
After a year of using this bike (training, competition) I can finally give a precise opinion. The quality-price ratio with all the components is great, the AXS is much superior and precise than the mechanical. The only drawback for me would be the brakes, which already take play from the first months and do not have the expected power. The second and last small downside would be the lock control, which is not very optimized (I think), I recommend you to change it for a rockshox onelock. Overall, it's a great bike, responsive, playful and with great performance and comfort! I recommend it without hesitation
Great bike for a great price. Worse brakes, replaced with Shimano. Comfortable suspension, great off-road, on roads I brake both shock absorbers and it's great. You won't find better for the money.
Absolutely easy and efficient cycling 👍
I love this bike. At the same time, you get a top product at an acceptable price... Of course, the large discount made me choose this... And I'm glad I trusted it.
An incredible bike
A very good light and responsive cross country mountain bike, very good value for money compared to the competition. Mountain biker for 12 years in club. Thank you Decathlon.

The word is not too strong. I thought I'd hang up my phone soon, but this mountain bike motivated me again. I don't know where to start. If ! what surprised me the most was the damping, its precision and its ''ease'' downhill for an XC, especially since the first outings, I didn't have the telescopic saddle. I go better than with my son's LP in 150mm and big crampons. The grip, the traction, and here too, the precision, uphill are great. I was thinking of changing the stem for a higher one, but surprisingly I am very comfortable, the position suits me. I regained sensations and pleasure. In short, a new youth. The equipment is top notch, the saddle comfortable. Downside on the brakes, but they do the job, all the same. Leak on a Mavic rim, changed in after-sales service. So much technical progress in 35 years! Congratulations to the Decathlon developers/designers/testers. I forgot the 6 star sale price! !
I just got this war machine from my wife for my birthday (happy surprise with the complicity of Olivier (decathlon Lambres-lez-Douai) to replace my xc500s which was already working very well. used last night for the first time in semi-nocturnal and what can we say other than that we change the world, a real treat in every sense of the word apart from the slightly hard saddle 😂bravo decat for all your products which make the competition pale and a big thank you to the entire Lambres-lez-team Douai!!👍👍
Another world after 30 years in semi-rigid. more performance, very directional and super efficient when climbing while remaining in the saddle. It's a great bike. the downside to the 29' is less agility but I imagine it's the same for everyone. A big thank you to Lounes from the Decathlon de Montbéliard cycling department for his professionalism and his very good advice.
After two months and several outings in all weather conditions, fantastic efficiency. Light and responsive, precise in trajectories, a real treat. Thank you to the Saint-Etienne Monthieux cycle team for their availability, efficiency and patience.
Good mountain biking for me who has been practicing mountain biking for 40 years. Adapted developments, good braking. The only thing missing: the telescopic seat post that I assembled myself.
