Questions & Answers

Look for product information, frequently asked questions, opinions...


I am 5''5 guy and this bike seems to be the only one in budget for me so would it be okay if I buy it? or would it be wise to wait for the S sized RC120 to be back in stock.


Unfortunatly this is a model we will not carry forward.

Hello- I am looking to purchase a road bike as a 5’4” woman. The model ( Triban 100 aluminum)- (5’1” - 5’5”. I am wondering if I would fit a small bike size at 5’4” .


Yes a small should fit you correctly. You will of course need to adjust the seat height.

This bike is listed as womens but sizes listed by Decathlon do not match suggested sizes in product information section which are slightly smaller. Is this bike unisex sizes or womens? I am a 5'7.5 woman and would like to know which size to get. Thanks.


You are really between sizes. There are several factors that go into proper sizing. Your inseam and torso legnth are key. If you are built 50/50 you might lean toward the small. If you have longer legs and a shorter torso, you might benifit from the medium. ( side note, I am 5'7" and ride a medium)

I'm a 5'9" guy. Is the main reason this bike is a women's bike and not unisex the bike seat? Any other differences that will make it not a good fit? And as someone who is 5'9" with long legs, should I go with a medium or a large?


Correct - not much difference except the seat, I am 5'7" and the medium is a great fit for me. I have slighly longer legs than torso. In your case, I might opt for the Large.

Excellent purchase. Quality price

Great entry-level road bike

I bought it 3 days ago in size XS. I'm 1m60 tall, so frankly it does the trick, I touch the ground. The bike is already assembled which is practical. It is light and pleasant fluid. ONLY downside, the saddle which I am going to change because it is too hard and uncomfortable for me despite being held with foam. I recommend this product in any case, for the price, it's worth it for starting out on the roads.

Very pretty and very complete in details.

Good bike to start riding on the road, it is very thin and light. It has many extras and everyone likes the color it goes in.

Great racing bike for the summer

I bought the bike for my wife, in this green, similar to the Bianchi Celeste. As a Bianchi fan, I like it and of course my wife likes it too. It's also like the green of the Mediterranean where we stored the bike, on the beautiful Greek island of Samos. We vacation there regularly. Technically the bike is completely fine, the Micro shift brake lever in conjunction with the rear derailleur does its job. It's a mono, so there's only a switch on the right. However, the crank is very soft and, with 40 teeth, is not particularly mountain-friendly. I therefore installed a different crank with a 36 chainring. The approximately €40 was well spent. A firmer crank and a gear ratio in conjunction with the largest rear sprocket, I think it's a 34, so you can manage a slight gradient of 8 to 10 percent and that's quite common on the island. So all in all, for the price and 20 to 30 km a day, it's a great affordable racing bike. By the way, the additional brake levers on the top of the handlebars are very comfortable, especially for small hands. And the color is wonderful, unfortunately it's not available at the moment. But white is also a summer color. However, if you drive or train more often per year and more kilometers per day, you should dig a little deeper into your pockets and spend more money. The frame is valuable and stylish, but still quite heavy, so the question arises, is it worth retrofitting later? In any case, I would still buy it again in a heartbeat.

Nice for a beginner like me

Great bike for beginners

This is my first road bike, bought 3 months ago to start road cycling. Great for getting started, excellent handling, the double braking is ideal for the city and to get used to the position, the gears shift well. I use it for my daily trips in the city and bike rides (for the moment tested on rides up to 100km), but already 800km done with it and I love it! I simply replaced the stem with a shorter one for a better position (I took size S for 1m63). As a small fault I would simply say the tires which I find unreliable on wet roads, I will certainly replace them next winter. In any case, excellent value for money.

Very good beginner bike

Very good bike to start road cycling. The double brake system guarantees user safety. The saddle is comfortable. However, I recommend buying automatic pedals and shoes to have more fun during long outings.


beautiful bike I love it was a gift I recommend

icon-circle-checkmark verified purchase

perfect for getting started


The bike is absolutely not quality, the tires are not at all up to what one would expect from a bike at this price and from a distributor such as Decathlon, tire which explodes (so change the tire AND of the inner tube) during the warranty period but nothing can be done, neither customer service nor the workshop want to take responsibility while the pressures used are those recommended by the workshop during the 6 month maintenance and mentioned on the tire. Tire which punctures again (inner tube included too!), 2 months later, even though the bike has not been ridden for the last month, and it has been reinflated every 2 weeks, again, on recommendation of the workshop. And still no support from Decathlon, everything is still at your expense!!

Excellent choice for getting into road cycling

I bought this bike 6 months ago now. 1000km traveled with it! Outings up to 100km. It's a reassuring bike (single chainring, double brake lever, good position with good weight distribution which makes it predictable and stable even at high speeds up to 80km/h downhill), easy to handle and very comfortable while having a dynamic enough frame to have fun sprinting and doing good climbs. I can only recommend it as a bike to discover the road. The only two limiting points of the bike are: the tires which are a little slippery when the temperatures drop and the rain is present... To be upgraded for winter outings. And another improvement, the 40 teeth crankset could have a few more because with more regular training we reach the max quite quickly even on the flat. Today I invested in a better racing bike but I still have the pleasure of riding the EDR Easy for all my daily trips.

Great product for beginners

Very nice bike, comfortable and practical!

I bought this bike three months ago and use it daily. I am glad ! I also covered 200 km in 3 days and had no problems. It is reliable, comfortable, light and easy to use. I recommend 100%.
