Gift for my husband, he is delighted to be able to surpass me now - I am already on a gvl520 myself -, impeccable for small gravel tracks as well as over long distances, it holds up. He changed the saddle but that really depends on each person's personal comfort. Only flaw: the assembly/adjustment of the Shimano group + brakes is always very approximate, you absolutely have to go through the workshop before leaving Decathlon with it. Good 1st gravel, good value for money
Great bike, I highly recommend, versatile and comfortable. On the other hand, Decathlon could make an effort on delivery: at this price, it could be free.
Purchased in June I had already given a first opinion for the delivery and assembly which went very well. For 5 months I have driven 1500 km with a total D+ of 31000 m. the bike is very maneuverable on completely rotten roads, on paths and on tracks that I used to take with my mountain bike. I go everywhere but on big steep slopes, especially at the end of the outing, I am sometimes at the limit of my strength. I would have liked to have a 40 at the rear or even a 38 by re-staging my cassette with the 11 serving me very little. But the derailleur cannot take more than 36. The cover is average. A derailleur with a long cage that could accommodate a crown larger than 36 would have been welcome
This opinion will have to be confirmed over time but on the first test I am completely satisfied. Excellent preparation by the Argentan store workshop (61). There are still a few small personal adjustments to make, stem height, handlebar inclination, saddle height, that's normal. I hadn't ridden a road bike for a good twenty years, this bike is totally suited to my return, the longevity remains to be tested.
I've only ridden a trekking bike before, this was my first bike with racing bike handlebars. I ordered it after the positive review in 'Rad' magazine in the gravel test. I didn't have the opportunity to test it in the store and blindly ordered size M. I'm very happy with the size (I'm 175 tall). The circuit was a main argument for the purchase, it is very good! The various mounting options make the bike absolutely suitable for everyday use; with different tires it would also be a good replacement for a racing bike. I've had the bike for a year now and am completely satisfied (top value for money, although I bought it for €1099)
Top bike for the price definitely unbeatable for more money the bikes are a bit lighter but the overall package from Decathlon is really unbelievable, you can ride it in a totally relaxed manner and also with real power. I have two other bikes MTB and RR, although they are lighter but this one is very Track-steady, reliable and robust, there's nothing to complain about
Be careful, tire defects often puncture
Ultra-fast handling. Driving comfort and precision. He does the job. Its transmission, its frame, its handlebars make this bike a versatile road and trail bike. Its color gives it a look that stands out from classic tones. This bike has character. Small downside, I had to go back behind the transmission adjustment. In fact the upper stop was set on the penultimate small sprocket and the chain was rubbing on the front derailleur fork. Anyone who doesn't touch this must make a trip to the workshop as their first outing. On the occasion of its first service included within 6 months of purchase I will refine the transmission adjustment to eliminate a noise which has been present since the 1st day.. In any case as a first Gravel I recommend this model whose price is very reasonable. The competition would offer the same configuration for around €2000. We are well below.
It's a good starter bike. Has good robustness and great shifting range for climbing and long flat stretches of the road. The color is amazing! Used it 500 km so far. Minor adjustment of rear derailleur cable needed every 200 or so but I switch a lot riding in mtb like terrain. Perhaps a better shifter cable is going to perform better.
Bike purchased on 07/29/2022. at reception, I do a test, nothing is adjusted correctly. I go back straight away and it's ok. For health reasons, I was only able to ride from June 2023. 1st outing puncture, during repair, difficulty putting the wheel back in place. I brought the bike back to Decathlon and there they charged me 16E for tightening the rear wheel axle... normal wear and tear on the bike??? (less than 100kms and still under warranty). Since then, on every outing I have had a puncture at the rear, even with preventive fluid (due to bad luck or...) I have come to wonder if my rear tire has a manufacturing defect. Additionally, the pedals touch the front wheel when cornering and this can be dangerous and prevented me from fitting a front mudguard. In short, I bought a bike for walking but also for going to work, but not sure enough to consider a return trip to work. Super unpleasant.
I bought the 520 subcompact about 8 months ago. Very quickly, I realized a first problem. Upon receipt, my front disc was warped. The seller changed it for me and gave another one (disc with a different shape from the back) first unfriendly customization... In short. After 600 km (ONLY road use, no woods or gravel roads), I realized a second problem. The rear cassette "undulates" (when the rear wheel is free and moving, the cassette undulates). The freewheel starts to squeak and rub in the process (feeling like a dry, sandy ride). So I'm bringing it back a second time under warranty. According to the sellers, this is a known problem but never corrected by Decathlon. They change the rear wheel as a standard exchange. I'm leaving for around 1000km. The third problem appears. I notice a cracking sound in the bottom bracket. After a third warranty return, I was told that the boxes are known to be fragile. We regrease it and ride... Result of the races, over 8 months of use (on the road and cycle path) and 1800 km covered, I brought the bike back 3 times under warranty for various problems (adjustment of the transmission, brakes that do not jerk intermittently, freewheel that rubs and squeaks, bottom bracket that creaks)... For a bike at €1200 that's a lot. Only the aluminum frame is really qualitative... The rest is of poor quality... So, I strongly advise against this bike for enthusiasts of this discipline. This bike is a nest of problems and I am worried about its longevity and reliability over time. A family member purchased the women's version of this bike and is experiencing the same issues. Run away from this bike!
My brother and I both bought this same bike for a long trip to Norway (5000 km) Strong points: - Shimano 105 groupset: very reliable and for 1200 €, it's a big strong point to have this quality of transmission - Comfortable frame suitable for a long trip - Impeccable brakes: held the entire trip without problem Weak points: - Bearings: We both had to change the freewheel body after 2000 km. - Rims: the rear wheels of our 2 bikes (which were bearing the weight of our luggage rack) became warped after 3000 km. We had them uncovered immediately by a professional and the rim did not hold and cracked when the spokes were tightened. Result: we changed our 2 rear wheels. - One of our bikes had play inside the crankset, we took it to a bike shop who, due to a lack of a compatible small chainring, had to completely change the crankset. If you are going on a long trip abroad (in a country where there are few decathlons), be careful: the parts are not very standard. The praxis crankset is absolutely impossible to change in Norway for example. In conclusion, Decathlon has made compromises to keep the purchase price relatively affordable. Consequently, the wheels and bearings are of lower quality to make it possible to offer the 105 group in particular at a reasonable price. Decathlon, why not consider creating a bike packing oriented gravel bike? A standard all-Shimano bike that's easy to repair anywhere (even if it means going down the transmission range and integrating more solid components (solid rims, spokes that cross 3 times, and better quality freewheel) But, all things considered, the subcompact remains a good bike with many qualities and with which we have a lot of fun riding!
a discovery ! surprising, perfect!!!
bike remains efficient and comfortable on the road and beautiful path, if stony to avoid downhill the weak point are the brakes with mechanical pads and not hydraulic
A beautiful machine, new to me. I admit to having been well advised and received by the staff at the Narbonne store.
