Gravel / Gravé / Gnarmac / Groad / ATB

Would strongly recommend not buying one of these, it's a false bargain, esp. with the price increase (bought mine when it was 850€ - actually paid 999€ because I wanted the better paint, but the bike is more or less the same).
You're better off spending 500€ more to buy a bike with full hydraulic and modern standards, and not worry about having to replace things in the following months. I bought mine in 2021, so there might have been some improvements since, but, in no specific order :

• Broke 3 spokes on the rear wheel after less than 2000 km. I am 65 kg and was only using the bike to commute, on standard roads. It is apparently a known fact by Decathlon mechanics that the wheels are badly built, but some people have had a hard time getting the repair to be covered by warranty, apparently. I didn't even try, as they wanted me to bring back the whole bike to have the spokes changed, as well as having to wait at least 3 weeks (without a bike).
  
• On top of that, wheels suck. They're not just heavy, fitting or removing a tyre is a nightmare (or just random). It took me 1 hour, at home, to remove the Pirelli Cinturato Velo I had fitted on there. Same ordeal with the Overide it came with. I couldn't mount GP5000 on them. These are all fairly supple tyres that I can mount and unmount mostly by hand on my Hunt Superdura.
  
• TRP Hy-Rd are very likely to give up the ghost for no specific reason. One of mine did that after 3000 km. Went full hydraulic, but that required me to file down the ends of the cable stops so I could run the hose cleanly to the back (this wouldn't be necessary with the grvl 520 model which has full length cable outers). There's no space to use these little screw-on hose adapters. PM on the back meant I had to buy a BR-RS785 on top of the second-hand FM brake and levers I found.
  
• QR is not a problem in itself, but it means you'll have to buy adapters were you to replace the shitty OEM wheels with more modern ones.
  
• They're fairly hefty. In size L, mine weighs 12 kg. Admittedly it's equipped for rando (mudguards, aerobars and dynamo lights), but it's fitted with decent (albeit not super lightweight) components : 105 hydraulic, Thomson seatpost, 3T stem, non-padded SMP, GP5000, Hunt Superduras. I reckon it'd still weigh around 10.5 kg were I to remove the mudguards, the aerobars, and go tubeless.
  
• If you wanna actually do muddy rides, tyre clearance is very limited in the 700c model : you'll fit non-knobbly 38s with no space for mud (nor mudguards, of course), maximum.
