The Triban RC120 Disc comes already equipped with front/rear lighting and a bell. Decathlon has also integrated mounts for a rack and mudguards, as well as tire compatibility up to 32 mm. Therefore, the question of comfort on this bike does not arise in terms of missing basic equipment, but rather in the contact points between the cyclist and the machine: saddle, handlebars, tires, position.
Rack and mudguard compatibility of the Triban RC120: a limited choice
The mounts on the frame suggest that any rack can be installed. The reality is more constrained. Decathlon indicates that only one rack is compatible: the 500 OneSecondClip Rack. This limitation changes the logic of accessory selection, especially for those considering commuting or light bikepacking.

On the mudguard side, the mounts allow for installation without a clamp, which protects the aluminum frame. Installing mudguards on an entry-level road bike transforms the use: water and dirt splashes disappear, and comfort in the rain is nothing like a ride without protection.
Before investing in bags or a transport system, it is essential to check the exact compatibility with this model. A detailed guide listing the accessories for the Triban RC120 on Blaye Automobiles helps to cross-reference this information.

Saddle and shorts: the duo that changes long rides
The ErgoFit saddle originally mounted on the RC120 is suitable for short rides. Beyond an hour, feedback varies on this point: some cyclists adapt to it, while others quickly experience discomfort in the perineum or ischial areas.
Replacing the saddle is the first instinct, but it’s not always the right answer. A pair of shorts with a suitable chamois often resolves the issue without changing the saddle. The combination of both (saddle suited to one’s morphology + quality shorts) remains the most reliable solution for distances over 50 km.
Here are some concrete criteria for choosing a replacement saddle for this model:
- The width should match the spacing of your ischial bones, measurable in a Decathlon store with a dedicated tool
- A central cutout relieves perineal pressure, particularly useful on a bike with a semi-upright position
- The weight of the saddle is of little importance on an entry-level bike: prioritize comfort over grams saved
28 or 32 mm tires: the most underestimated comfort margin
The RC120 accepts tires up to 32 mm. This is a feature that many owners overlook, even though it represents the most effective and least expensive comfort lever on this bike.
Switching from 25 mm tires to 28 or 32 mm tires radically changes the bike’s behavior. The additional air volume absorbs road vibrations, reduces fatigue in the arms and shoulders, and improves grip on wet pavement. The pure speed loss is negligible for touring or commuting use.
With wider tires, one can also ride at a lower pressure, which further enhances the cushioning effect. On degraded roads or stabilized paths, the difference in comfort is immediate.
Handlebar tape and grips: absorbing vibrations at the hands
The handlebars of the RC120 directly transmit vibrations from the pavement to the palms. On rides longer than an hour, numbness or pain in the carpal tunnel frequently occurs. The original tape, which is thin, offers only limited cushioning.
A thick tape with integrated gel significantly reduces vibrations transmitted to the hands. The ideal thickness is above 3 mm. Some brands offer models with double layers of foam, particularly suitable for aluminum frames that filter shocks less than a carbon frame.
Additionally, cycling gloves with padded palms add an extra layer of absorption. This is not an accessory to attach to the bike, but the effect on hand comfort rivals that of changing the handlebar tape.
Repair kit and pump: the accessory one regrets not having
The RC120 does not include a repair kit in its standard equipment. On a ride of several dozen kilometers, a flat tire without repair equipment turns the outing into a walk.
The minimum to carry:
- A spare inner tube compatible with the size of the mounted tire (check the Presta or Schrader valve according to the rim)
- Tire levers to remove the tire without damaging the rim
- A compact pump that attaches to the frame or a CO2 kit for quick inflation
- A multi-tool with Allen keys to adjust the saddle, stem, or brakes if needed
The frame, stem, and handlebars are guaranteed for life by Decathlon, with a five-year guarantee on the fork. This long-term warranty justifies investing in comfort accessories rather than worrying about the longevity of the bike itself.
True comfort on a Triban RC120 does not come from a single miracle accessory. It relies on the addition of small targeted adjustments: wider tires, a saddle suited to one’s morphology, handlebar tape that filters vibrations, and emergency equipment that prevents ruining a ride. The model accommodates these modifications easily, and compatibility with the OneSecondClip mudguards and rack further expands daily usage possibilities.
