I'm very sorry to have to say this, but service is just really bad (and to some extent dangerous).

My experience:
1) Far too much waiting time, staff does not seem to be organized at all.

2) Missing simple tools:
Apparently there was an issue with the back-wheel that needed the tool to remove the cassette, that was however not available. Luckily they have been able to simply swap the wheel from a presentation bike (that apparently had a few scratches, but that is more or less fine for me).
When I was in the store and like to get the left crank changed (have a left crank with a pomermeter). But who might have guessed that, they don't have a simple tool to remove the plastic cap of the left crank.
On a serious note, which bike seller does not have the right cassette remover available? I even have these tools personally (in Europe, and now as well here in HK). All these tools you can get in a standard simple bike toolbox for

Faulty bike. Fragile and bad handling on the bike. Too heavy

I ordere triban rc 520 on 24/07/2020 and I got it delivered on today 15/08/2020 and the box it came in was tear and the bicycle got some scratches on it but it's fine I was happy that my bike was delivered to me but thay don't provide me any tools for installing pedals just got 2 Allen keys and the rear wheel and bracks is making noise and the rear gears are not shifting properly the chain keep making noise and shifting up and down I can't able to ride my new bike and I am feeling bad about. It was my first purchase from decathlons and this is very bad experience for me the decathlons store is 50km from my home i don't know what to do help me

I bought this bike 4 days back...And started riding for around 5 for couple of days and in just in time this bike gave me comfort to ride for 20km. Thanks for wonderful bike with Shimano 105 group set.

Performance of the bike is not comparable with cost paid. Wrong decision by me based on Decathalon sales team recommendation. My purpose of buying this bicycle is not fulfilled.

Been riding the bike for over 6 months and overall pretty happy with the bike.
Shimano 105 shifts great and getting 105 at this price point is awesome value.
TRP HY/RD brakes are pretty good - maybe not as good as Shimano 105 Hydraulic brakes, but for the price not bad. Carbon fork nice to have.
Claimed weight for size Med .is 10.6Kg without pedals - mine weighs with Shimano SPD clipless pedals, reflectors, water bottle cages & saddle bag: 11.4Kg. Not bad for an endurance Alu bike with disc brakes.
No through-axle which would have been nice to have with the disc brake wheel set - uses quick release skewers. Rims and tires are ok. Saddle not bad for something that came with the bike.
Overall I recommend this to anyone looking for an endurance style road bike with disc brakes.

Triban 520 is an amazing endurance geometry bike. And for the price of 74999 I wasnt able to find any aluminum frame road bike with carbon fiber fork, disc brakes, and a shimano 105. Most bikes with these specs are sold over 85000. The cost of the bike makes the bike even sweeter while riding it

I have been riding the bike for about 3 weeks now, and like the smooth shifting of 105 groupset. The wide combination of gears (2-11) allows easy climbs and sprinting capabilities too, but this one is genuinely not a racer. Apt for endurance riders and touring enthusiasts, this bike has a smart frame, ergonomic handlebar, and saddle along with very effective disc brakes. All in all, I am satisfied with my choice and would urge others to give it a try too. A very impressive product from Decathlon at a good price range. 105 groupset is hard to get in the market anywhere below 90k, whereas Decathlon brought it out for a competitive price (75k). The disk brakes are from TRP that has emerged as a real competitor to SRAM and Shimano.

as i can see the bike weight it almost 11kg as recommended maximum weight is only 8.5 kg

This bike is value for money and a great option for anyone considering a relaxed geometry bike. Build and quality are what is expected for a bike at this price. 105 drivetrain is a bonus.
