When will it be back in stock? and would this deal still be ther when it is back in stock?


Unfortunatly this is a model we will not carry forward. We may have a similar model RC 100 in stock in your size

By Thierry on Aug 15, 2023 | STAFF


Just want to confirm, when I purchase this bike it actually comes with pedals? I do NOT have to purchase bike pedals separately?


Correct - pedals are included in with our bikes.

By Thierry on Sep 5, 2023 | STAFF


Is the small size ever being restocked?


Unfortunately, not in the near future, But the RC100 is available.

By Thierry on Sep 11, 2023 | STAFF


Could I add gravel tiers to this bike? Do you sell them?


This bike is not desgined to offer the clearnace required for gravel tires

By Thierry on Sep 18, 2023 | STAFF


Would I be able to swap the tires on this for some more aggressive tires if I wanted to do some gravel riding?


You can put some wider more agressive tires on this bike, if you have the clearance so it would depend the width of the gravel tire. up to 30mm you should be fine

By Thierry on Sep 26, 2023 | STAFF


Several answers refer to this bike(RC120) being discontinued; will there be a new model to replace it?


Not in the short term. We may explore again for US import begining in 2025

By Thierry on Oct 9, 2023 | STAFF


Hi, I am right between sizes M and L for the Triban RC120 road bike. I am 5'11" and shorter legs with approximately a 31-32" inseam. What is the standover height for both the M and L frame for the RC120? Thank you


You should opt for the large, though you may not have as much stand over clearance. I am 5'7" with a 30" inseam, and fit the medium perfectly.

By Thierry on Oct 30, 2023 | STAFF


I’m 5’11” with a 32” inseam. I’m fairly proportional in regards to torse, legs, arms, etc. The size guide says I’m right between a M and L. What do you recommend?


Based on your height and inseam, I would definely recomend a large

By Thierry on Nov 24, 2023 | STAFF


I am 6 ft and the guidelines on this website say I should buy an L. However, other Decathlon websites of European countries (France, Italy, Germany) have a slightly different scale and I would be between M and L. What would be your advice? Thanks


Would Suggest a Large - at 5'8'' I am a medium to offer prespective.

By Thierry on Jan 9, 2024 | STAFF


Would you recommend using this bike for a half Ironman?


You certainly could use this bike for 1/2 Ironman, I would add a set of Aero bars and you would be set.

By Thierry on Feb 8, 2024 | STAFF


I was wondering if there is more size M coming out?


Unfortunately not - we will not be replenishing this model.

By Thierry on Feb 27, 2024 | STAFF


Is there a way to purchase a new front wheel? I was in a car accident and only my front wheel was damaged.


For sure, the wheel is a stanard size and should be available at your local bike shop. The components are 100% standard and should be easy to find. If you want to re-use exisiting parts, you can ask your local bike shop to rebuild the wheel on a similar rim reusing your hub, and rotor if they were not damaged in the accident.

By Thierry on Mar 11, 2024 | STAFF


How much assembly will I need to do when I buy this bike and will I need special tools?


This bike will arrive 95% assembled. You will need to put on the handle bars, install the seat post & pedals and complete the tire inflation. All the tools you will need with the exception of an air pump are included. - Attached is the assembly video of a similar bike to give you perspective:

By Thierry on Mar 21, 2024 | STAFF


What is the max tire width I could install on this bike without having to change the wheel frames?


The largest tire size you can put on this bike is a 700 x 32mm.

By Thierry on Mar 25, 2024 | STAFF


Will I be able to upgrade this bike to a 10-speed groupset (such as Shimano Toagra)?


Yes you will all the parts on the frames set are 100% standard.

By Thierry on Apr 30, 2024 | STAFF


I’m 5’6 with a 28 inseam 140 pounds, would the xs work for me or should I go with a different model?


You would fit better on a small - maybe explore the GRVL 520 in a small.

By Thierry on Apr 30, 2024 | STAFF


im 6-1”, I really want the drop bar version of this bike however it’s not available in the proper L size. Is XL ok or do I need to figure something else out?


These bike actually run a little on the smaller side - You should be fine with an XL.

By Thierry on May 1, 2024 | STAFF


I am 6 foot and really liked this bike, do you think xl is too big for me? Thats the only size left


I think you will be fine on the XL as these bikes run a little on the small size.

By Thierry on May 3, 2024 | STAFF


Im a men 6’0” and weight 237 pounds. Will XL be a good fit or should I go for L size?


Depending on your flexabilty - but I would go with a large with 80% confidence. If you have poor flexability the XL might be more comfortable but you will have less inseam clearnace.

Very good

It is an excellent bike in terms of value for money. The only negative is that in the decathlon in Satu Mare there is no mechanic to adjust the shifter, the bike changes speed randomly while riding and I had to take it to a mechanic to make it OK. This happened to me with the other bike I purchased earlier. Otherwise the bike works very well, I did about 200 km in 2 weeks.

Correct, except…

Correct, apart from the brakes which make a huge noise when braking, the adjustment needs to be reviewed

Having purchased the bike with scraping on the pedal, they were met with a water bottle, no pedal change, which they did easily the next day in San Giovanni Lupatoto

Versatile bike

I bought this bike in October 2022 I use it every day for cycling (10km per day) it is ideal with a luggage rack. I also use this bike for road bike outings, it's very good for starting the activity, it is sometimes a little heavy for the passes towards my home (Haute Savoie) but given the price it's worth it

Good price/performance ratio. The only limitation is the mechanical disc brakes which are difficult to adjust. Most likely everything will be much better as it settles down. However recommended.

icon-circle-checkmark verified purchase

First satisfactory outing, it goes much faster than a mountain bike, it's surprising! To see over time but for the moment the bike is very beautiful and practical, I am happy with my purchase. Hoping to never have to return to this positive review!

Unbeatable price Rc 120

Downside on the pro max front brakes!! Front derailleur took up some play quickly.. happy with my purchase transformed into Gravel…
