I am really pleased with the bike. It runs perfectly and is the best value proposition of any gravel bike on the market today.

Excellent Gravel - unbeatable value for money

Super Gravel, excellent frame, reliable Shimano 15 groupset and top-notch Touareg tires. Catastrophic decathlon settings, I took everything back home.

Excellent bike at a price…

Excellent bike at an already significant price. The rear hub is bent. Return of cycling at Decathlon: come back in three weeks! It's too bad. What I conclude, no preparation of the bike and ineffective after-sales service. I hope to have a real solution before the end of the holidays.

Great bike

Great bike for great outings. Before first use, check that the derailleur and chains are properly adjusted, otherwise there will be problems changing the chainring. Easily made in a Decathlon workshop.

Braking adjustment...

The braking adjustment was complicated, so not crazy efficient, on the other hand, driving is very pleasant, light and fluid

Very good gravel, just…

Very good gravel, just a small downside, pedals much too tight, impossible to remove them to install my SPD, forced to return to the store to have them removed.

The price-performance ratio for this bike is excellent, the bike is fast, comfortable geometry, I am satisfied.

Rear sprocket swings

The freewheel rear sprocket oscillates quite a bit, it could be a defect but the response from the manufacturer's technical assistance is that "it's normal". Nothing to say however about the assistance of the shop which was very helpful.

gravel bike at an affordable price, after much research on the market I came to the conclusion that at this price and with these components I couldn't find anything better. Already tested on long routes, I found it very comfortable both for the geometry of the frame and for the subcompact crankset which I had never had the opportunity to try before. Highly recommended!!

Excellent bike

I even use the bicycle for a use that is not even its intended purpose, for daily commuting, but I must say that it serves its purpose perfectly. As it is light, you can easily take it on the train and with the double platform you can roll quickly on flat terrain and downhill, but it also has enough gear for more demanding climbs. For comparison purposes, I do a climb with more than 10% of incline on the way home and even with panniers on the bike I climb perfectly. Now we need to test it on the trails

Be careful before buying it!

Bike purchased at the end of February. After 4 months (3 outings per month). The derailleur broke in half and broke the chain. Thanks to Decathlon in Claye for helping me out, but I had to pay for a chain again and I no longer have a front derailleur (they no longer have Shimano 105). Probably in the resale box but at this price, with the little use and the purchase 4 months ago, I would have liked the derailleur to be under warranty... I have just bought a new bike for my partner, I'm thinking of bringing it back because in terms of after-sales service, Decathlon is not at the top.

The best option in bikes for some guys that loves cycling

Great gravel bike

Very nice gravel bike at a reasonable price. The equipment is absolutely fine. It rides perfectly. I've been using it since March and I can't complain. Of course the gears need to be adjusted now and then, but that's not a big deal. Bowden cables stretch with use. I'm completely happy with this bike!

Big problem wheel and transmission

After 2 years of very moderate use: a little cycling work and weekend outings of 30 terminals, the results: a wheel changed (broken freewheel) chain and cassette to change the transmission is said to be 105: not the chain and not the cassette, low-end quality... and the bike service, when they change your wheel, don't even look at the wear of the chain.... too bad, it takes 5 seconds with the tool.. .. and after complaint, customer service doesn't even apologize! So count on 200 more balls after 2 years!

It's driving decently for now
