Great bike for the money?

I didn’t think there be a huge difference between this bike and the big box store bike I already had but I was sorely mistaken. This is a great bike and I didn’t have to spend as much as I thought I would for a bike as nice as this. It rides super smooth and is very light and easy to handle. I thought I wouldn’t be able to handle only having the one set of brake handles at the curve of the handlebars as my old bike had two sets but I had no problem getting used to that and the brake/shifter combo is great. The shifter is smooth and I had no problems getting used to this setup. I loved this bike!!

Great bike

My first road bike and I loved it.

Riding the new one Triban RC 120 CN FR

Made for above-par endurance at the price

I am a 50-year-old male, 1.65 meters tall and 90 kg in weight. I bought this Triban RC120 road bike on 10 March 2021 at the Shah Alam outlet despite test riding it at the USJ outlet. The reason why I chose the Shah Alam outlet is that this is the nearest outlet that offers bike fitting before purchasing the bike. I am happy to say that I am relieved that I did the bike fitting first before buying the bike. The fitting process surely confirmed my selection of the extra small (XS) size of the bike which I rely on the bike selection in the Decathlon outlet and further bits of advice from blogs and YouTube on taking a smaller size. The fitting also helped to ensure the measurements are done according to my height, the hand-reach to the handlebar, knee and toe alignment, and including the lower backbone checking (ensuring that the bone is not moving when pedaling the bike), which is an extra fitting done and not found in bike fitting videos in YouTube. Since purchase, I have ridden the bike twice for 35km on each ride, along the motor lane on the KESAS highway and I am certainly a happy person as I was writing this review. The bike was correctly fitted for my size, the ride was smooth and the bike parts reacted to what I was looking for in an endurance road bike. I read some poor reviews of the Triban 120 bike especially on the brakes, of which I am very satisfied that it is responsive and does not create any noisy sound even braking at high speed. The caliper brake is reliable and easy to operate even when I want to take the wheel off to load the bike into my car. Another part that I wish to comment on is the saddle. Even without wearing my padded shorts, the saddle was comfortable for the last 2 rides. Maybe I already accustomed to riding a folding bike for the last few years on a 20 – 50km distance. The fitting also helped to ensure that I have no pain while pedaling. The Microshift gearing is also flawless which any avid users of the Microshift system will agree. I did admit that I learned how to operate the shifting from YouTube and found it to be reliable based on my riding style. To me, shifting the gears is about anticipating the change in the elevation and need for speed. Since my riding purpose is more towards long-distance and metabolic workouts, I trust the Microshift is sufficient to meet the purpose. Also maybe that from my folding bike days, I was familiar with Shimano Tourney (1 X 8), and migrating to Microshift (2 X 8) is just another chain shifting from smallest to largest cogs, front and back. Also, the tire which comes with 700 X 28mm puncture-resistant, I am comfortable with the road riding and maybe going off-road once in a while through the estates or kampong for shortcuts. I was prior advised of the complications that I may encounter if I want to change the tire if punctured, but that is the least of my concern for now.

It's ALMOST perfect.

The RC120 is by far the best bang-for-buck road bike on the market here in Malaysia. I generally do not have any complaints except for one. Due to Covid I only ride my bike in a public park that goes for about 3.7 kilometers per-round. I've done so for the past 20 days and riding in between 30 - 60 kilometers on each of those days. The park's road is well maintained, there is a very little amount of loose rocks and is paved with asphalt all the way round. On my last few kilometers today 2 of my spokes on the rear wheel gave out and came loose. Upon further inspection, I found that the point where the spokes attache to the rear hub had snapped and could not be re-installed and tightened. Which meant that my wheel no longer spun true so it would make co ntact with my rim brakes at every turn of the crank. This bike is barely 1, 1/2 months old and has only been cycled in a controlled environment. This is not a matter of premium-for-quality and is now a matter of safety. Luckily I was at a relatively low speed but if the spokes had snapped while I was decending a hill, the result could have been much worse

Great bike for a beginner

Got this bike 2nd hand after scouring reviews online for it. Major thing to note is that the sizing chart by decathlon might be off. If you have shorter legs and arms (light me), at 165cm, I should ideally buy 1 size smaller. You may want to test the bikes out at the nearest Decathlon first before buying. At size M, my feet were still tip toeing and my reach is still slightly extended. If buying online, I'd check where I am on the sizing chart, and buy one size smaller (You can always extend seat tube/stem length as needed, but you can't downsize a bike as easily.) But again, this only applies to those very near the edges of the sizing chart. at 165cm height I could've went with an M or S. Pros: Ride wise, the bike feels very nice and speedy. I love riding it around and it feels great. Everything is smooth and runs very well, even on a second hand bike. The bike as a whole is light, everything is great and climbing isn't an issue. Gravel riding is also fairly nice, but I'd just use my mtb for those tbh, gravel riding on road bikes are very uncomfortable. The bike itself is stiff and rigid, light enough to easily climb hills with no issues and glides fast enough to work well. It's a great bike for a beginner with a decent upgrade path. Cons: Lubrication: I'm not sure if it's because I bought this second hand, but the bike was only 1 month old. The bike was dried out, sprockets squeaked, pointing to a lack of lubricant. They might've used a dry lubricant out of the store. So I'd recommend to check your bike's cassette, derailleur sprockets and chains to see if it's lubricated. Ideally, your first week riding should also involve cleaning your bike out. Use a degreaser (Check lazada) on the cassette, derailleurs and chain (To wash out any old/dried lubricant/dirt). Then, dry the bike and use an aftermarket lubricant (Like Muc Off Dry/Wet chain lubricant or WD-40 BIKE dry/wet chain lubricant). Brakes: The brakes might need further adjustment and fine tuning. But if you're willing to spend, upgrade it to a proper after market brakes. If you choose between rim brakes or disc, best to buy the disc brake version of this. Shifting: The shifting is great for a microshift. But I'd suggest upgrading it to a Sora or something. The gears feel like it's missing 1 set. I'm always putting in too much power or too little power to my wheels between gears. Wheelset: It works. The originals are absolutely fine. But the most obvious upgrade (and one you should DEFINITELY start with) are the wheels (Rims, tyres). If you want a lighter bike, I'd suggest upgrading to carbon rims. I'd also change the tyres to a 700 x 35c or higher as this will cause less punctures/blowouts plus the benefit of being able to ride gravel comfortably. In short: To upgrade, upgrade your tyres first if you're on a budget to an aftermarket 700 x 35c or higher. Then your rims. Then your brakes. Then your derailleurs and shifters (At this point you'd probably buy a new bike).

Good bike but not according to spec

The crankset is not Shimano Tourney as what is mentioned in spec, there is no brand. Pls update info page accordingly so buyer are aware. Other than that no complaint

Hi Lau,

Thank you for the review about our product: Triban RC 120 Road Bike 8sp - Grey!

I am glad to hear that this bike is working well for you. Regarding the crankset info, indeed it is not Shimano Tourney, this was actually for the older batch of this bike model. We will feedback to the website team to update the correct information on the product page as soon as possible. Our sincere apologies on this oversight!

Nevertheless, thank you very much for your support, and I hope to hear from you more and hope to see you in our stores too!

Stay healthy, keep fit & stay happy always! :)

Cycle Good, Tyres bad

I have used this cycle for about 4 months now (regularly, 2-3 times per week at least), so hopefully I can fairly judge the product quality before writing this review. The bike itself is light and structure is solid for its weight. The gear transmission is not the best (having tried some of my friends' more expensive models), but we get what we pay for. Braking and riding is generally pretty good. The bicycle itself, I would rate it a 3 (or even a 4). As in most cycles from decathlon, you will need to have a few key accessories to go along with it. A kick stand, bottle holder, seat cushion/cover, lights (if you ride when it is dark) etc. It is a great beginners road bike version that does the job for the price. However, the worst feature is the tire and the tube quality. In the last 4 months I have used it, I have had multiple flats. I do not ride in gutters or dirt roads. I ride in the Singapore park connectors (and have tried it in multiple ones), but the end result is the same. People advised me to ensure the right tire pressure, which I did as well (I ensure that there is right pressure every time I ride it, or pump air). But regardless, every 3rd or 4th time I ride it, I encounter a flat (and I am a very careful rider). I have gone to decathlon repair center almost every alternate weekend to get it rectified and to tell you the truth, I am fed up. The repair folks tell me that it is fairly common with these cycles. Well, in that case, I'd say avoid this bike completely because maintenance is a big hassle here. and just yesterday, I got another flat, went to decathlon repair and they told me that now the inner tubes are out of stock (everywhere in Singapore). Based on my experience, I would say go for different models - maybe mountain type bikes.

Hello Kamat,

Thank you for taking the time to review our products. I am sorry to hear about your less than satisfactory experience with this Triban RC 120.

We suspect that there could be an issue with the rim tape which can be one of the causes of punctures even when you have taken precautions to pump the tyres at the optimum pressure (87-116PSI).

We would like to invite you down to our Bedok workshop to get your wheels replaced. Do book an appointment with us through this link. Do note that you may have to leave your bike with us in the event the new wheels are not in prior to your visit.

Thank you and have a pleasant day.

Your coffee shop commuter



Almost perfect, except for the minor scratch in paintwork that I noticed after delivery person has left. Ride was great still.
