Very solid gravel bike and great looks

Positive: + Quality is completely fine for the price + Color is very nice and not so boring + Braking performance is better than expected + Brake and shift cables or wires are on the outside of the frame, which makes handling and adjustment/replacement much easier + Lots of threads for attaching bags (fork, in the frame in two places, etc.) + Nice minimalist tools are included Negative: - Gear shift may need to be fine-tuned after assembly - Rubber protection, which is supposed to prevent the cables from rubbing at the front, sometimes slips a bit (luxury problem) I'm about 185cm, frame size L is perfect and there's still a bit of room for adjustment

Bought 1 month ago, I'm skipping the delivery which lasted 3 times the usual duration (package canceled twice because of paint problems then second package sent to the wrong store) these are things that happen. The first 15 days went well, the bike was nice but I still had to go back to the workshop to readjust the rear derailleur which had been hastily fitted. After 1 month of use, a cracking noise is heard in the frame, return to the workshop, I will have to wait 3 to 4 weeks. The bike is my vehicle for going to work, no solution is offered to me to replace it during repairs. This is a disastrous experience for my bike at Decathlon.

Best quality price report

Shimano 105 at this price... The bike is impressive, it offers high performance and I have full confidence in it. I use it for both sports and cycling outings. Small downside: I had to adjust the brakes myself and the gear change is imprecise due to poor adjustment.

Saving in the wrong place.

Why don't you make the bike about 200 euros more expensive and equip it with a fully hydraulic brake and thru axles? What a shame.

Recurring brake caliper problems

Bike purchased in 2022, after a lot of terminals on it I always had brake problems with the calipers. The pistons of the TRP hydro-mechanical calipers systematically end up no longer returning to the starting position, which asymmetrically and prematurely wears the pads until the piston comes out or completely blocks the disc. In January 2024 I made a return and after 2 MONTHS of waiting to order a replacement caliper (don't be in too much of a hurry) from the store and resolve the problem my 2 front and rear calipers are again stuck in the tightening position thus constantly braking the wheels. Despite the oil change, the latter do not return to neutral position and therefore need to be changed again... I will therefore have to get quotes to switch to mechanical because the complete hydraulic change costs around €570 at Decathlon. .. To be continued,

A good base but problems

This is my second decathlon bike. The first one (Riverside 7) was always extremely satisfying. This is unfortunately not the case with this one. The rim tapes were already missing, which were added by Decathlon after multiple punctures. Not great customer experience from the start. There were also missing screws which were added afterwards. But now more serious, I just broke my cassette body without any shock in the middle of a week-long cycling trip in Brittany with a friend. On the road. All one day after the end of the warranty year. I had to cancel the trip altogether due to a lack of parts available at Decathlon. The very big hassle... In short, I am very disappointed with Decathlon and for the moment have absolutely no confidence in this bike. It's a shame because it's very pretty and quite pleasant to drive. Pretty well equipped for the price. But clearly having to pay for a rear wheel again doesn't satisfy me at all. For the first time, I am disappointed by Decathlon and I am not sure I will buy a bike from this brand in the future.

Great gravel bike with top price-performance ratio

I was looking for an inexpensive gravel bike and found it at Dekatlon. I'm still really happy with it after a few weeks and can really recommend it.

Bike purchased 3 years ago

I had time to discover it, its good and bad sides. Overall it's a very good bike, one that I had fun with and still have fun with. It holds up, efficient and fast, I like it a lot. However, I had bad experiences: First, the Decathlon salespeople advised me to switch it to "Tubeless" since it is "Tubeless ready" = huge mistake. Never switch your bike to tubeless, it costs an arm and a leg (around 50 euros) and the fluid (which you will have to replace very often, because it dries and deflates the wheel) costs around 15 euros, it's a trick to pump yourself up your money. Nothing beats a good old two-euro inner tube that can even be sealed with a specially designed dressing. The second problem is the saddle, it quickly hurts the buttocks if the outing lasts more than an hour, bring a padded saddle on occasion. Apart from the inconvenience caused by the wheels which I find to be of poor quality and the saddle which is uncomfortable in the long run, the bike is overall very good, all the parts can be changed, nothing is sealed, which is quite cool. I note the price increase for this bike that I bought for 1000 euros, we will explain it by "inflation", even if the increase is enormous.

This my first bike…

This my first decathlon bike, I must say that I am satisfied so far. For the moment it's just velotaff.

Great value for money

Very good bike to start gravel/cyclotouring. Probably one of the best value for money possible. The brakes are a little finicky at times. The wheels are worth changing if you want more performance!

Mixed review

Moderately satisfied with the GVRL520 subcompact. I bought it following the end of road and triathlon competitions and the resale of my bikes to continue riding long distance pleasure outings + cycling trips. Pleasantly surprised by the behavior of the bike and disappointed by certain peripherals. 4000km done including a 4 day bikepacking trip (720km) without worries. (loaded with saddle bags, handlebars, top tube, and fork + my 85kg) I changed the wheels for Mavic Crossmax SL, put a longer stem and carbon seat post with more setback (parts already in my possession) Big negative points of this bike, the very low-end wheels and QR axle, which strongly limits the choice during an upgrade (or with conversion kits hard to find), and the brakes which are not up to par with the rest of the bike. The 105 transmission works very well but the 48/32 crankset is a little big for Gravel/travel use. The bike would be perfect with a fork for thru-axle wheels, a grx 400 type hydraulic group and its more suitable 46/30 crankset.

Good product

Good bike! Braking is a limit in certain places.

After 1 year

After 1 year of use, the bike already has many repairs under its belt. Now the rear rim is starting to crack in several places. It starts to do a lot in a short time.
