The Triban RC120 has long held a unique place in the Decathlon catalog: that of the first accessible road bike, with a low price point and components designed to introduce the discipline without breaking the bank. With the gradual repositioning of the Triban brand towards Van Rysel, this model is changing its status. It no longer targets quite the same audience, and its direct competitors have also evolved.
Aluminum 6061 T6 frame and sloping geometry of the RC120
You may have noticed that some road bikes give the impression of being “high-legged,” with a nearly horizontal top tube? The RC120 takes the opposite approach. Its sloping geometry lowers the top tube towards the rear, resulting in two concrete effects.
The first is postural: the riding position remains more upright than that of a pure racing bike. For a cyclist who goes on rides lasting two to three hours, this posture reduces tension in the lower back. The second is structural: a more compact rear triangle stiffens the frame without adding weight.
The chosen material, aluminum 6061 T6, is found on nearly all entry-level road bikes. It offers a good compromise between lightness and fatigue resistance. In this regard, the RC120 does not stand out from its direct competitors. The difference lies more in the quality of welding and tube finishing, where Decathlon benefits from its vertical integration (in-house design and production).
A test of the Triban RC120 against the competition shows that this frame remains relevant for cycle touring or commuting, but it reaches its limits on demanding hilly routes.
Transmission and braking: what limits the RC120 on the road
The transmission is the area where the RC120 lags the most behind its rivals in the same price range. The original setup relies on a basic configuration, while competitors already offer Shimano Claris (2×8 speeds) with better gear ratios.
Why does this choice matter? On flat terrain, the difference is subtle. However, as soon as a hill appears, limited gearing forces the cyclist to push in ratios that are too spaced out. The cyclist loses pedaling fluidity and tires the knees more quickly.
On the braking side, the RC120 uses rim brakes. This system works adequately in dry weather but loses grip in the rain. Competing bikes that incorporate mechanical disc brakes at this price level offer a clear advantage in safety and braking modulation.
- The single or basic double chainring transmission is suitable for flat or slightly hilly routes, not for climbs.
- Rim brakes require regular replacement of brake pads and more frequent adjustments than mechanical discs.
- Switching to wider tires (up to 32 mm according to user feedback) partially compensates for the lack of comfort related to less progressive braking.
Triban’s repositioning towards Van Rysel: what it changes for the RC120
The Triban brand is gradually disappearing from the Decathlon catalog. Road models are progressively migrating under the Van Rysel banner, while bikes more oriented towards leisure or fitness are being redirected to BTWIN or Riverside.
For the RC120, this transition has a direct consequence: the announced successor will be rebranded Van Rysel and will be more expensive. It is expected to feature a Shimano Claris 2×8 transmission, which addresses the main weakness of the current model. The price positioning will rise in return.
This shift alters the comparison grid. The current RC120 was compared to bikes around the same low price. The future model will compete with road bikes already equipped with Claris or Sora, such as some entry-level Canyon Endurace models or newer Btwin models.
What type of cyclist still targets the current RC120?
The RC120 in its Triban version remains a coherent choice for three specific uses:
- Commuting on mixed routes (road and bike path), where the robustness of the frame and the ability to fit wide tires matter more than the transmission.
- Discovering road biking for a cyclist who is not yet sure if they will continue in the discipline and wants to limit the initial investment.
- A modular base for light bikepacking, thanks to the mounting inserts for racks and fenders present on the frame.
On the other hand, a cyclist planning regular rides on hilly terrain or aiming for performance, even modest, would benefit from investing directly in a model better equipped with transmission.
Triban RC120 and rivals: the real criterion for choice at the time of purchase
There is a strong temptation to compare entry-level road bikes solely based on the displayed price. The RC120 shines in this area. But the real cost includes almost mandatory upgrades: changing the saddle, replacing the original tires, possibly adding clipless pedals.
A competitor sold slightly more expensively but delivered with a Claris transmission and mechanical disc brakes may end up costing the same total price after a few months of use. The choice of the right frame size weighs as heavily as the equipment: a poorly adjusted bike generates pain that leads to abandonment, regardless of the price range.
The RC120 remains a decent bike for its catalog price. Its main strength lies in immediate availability in Decathlon stores and the integrated workshop network for maintenance. For a first road bike, this after-sales safety net has no equivalent among brands sold exclusively online.
