The RCR range
The RCR range is a real treat for cyclists who want a complete bike with no compromises. For this bike, performance was our priority. The cross-sections of every tube have been calculated to be as efficient as possible in the main wind angles (-15°/+15°).
This bike falls within the "lightweight aero" category of bikes, offering the perfect balance between weight, rigidity and aerodynamics, resulting in an exceptional bike.

What's the difference between the RCR and the RCR Pro?
What makes a carbon frame is its geometry, its shapes and its layup. The layup is how the carbon fibres are assembled. Not all fibres have the same properties.
On the frame of the RCR, we only use high-modulus fibres. On the RCR PRO, we've chosen exceptional fibres that make the bike stiffer in the areas that are put under the most stress and that slightly reduce the weight.
The RCR PRO is ready to compete at the highest level.
A closer look at the frame
The RCR's frame weighs 830 g (painted) in size M
The RCR's fork weighs 380 g (painted) in size M
The frame can take tyres up to 33 mm wide.
There may be slight variations in weight depending on the colour (+/- 50 g).
SEVERAL FINISHES TO CHOOSE FROM
Depending on the groupset and wheel configuration, we offer different finishings to choose from so that you can ride in a model you styled yourself.
The RCR and Pro frames come in a raw carbon finish covered in a matte varnish. This means that the carbon fibres are visible since they are not covered by paint. Every frame is unique as the 450 pieces are individually laminated by hand in the mould, which saves up to 100 g.
COCKPIT
We've integrated the parts of the headset so that the RCR steers smoothly while remaining easy to maintain.
DEDA x VAN RYSEL Superbox EVO: the stem is lightweight yet sufficiently rigid
XS: 80 mm

SHIMANO 105 DI2 grouspet and INPEAK power sensor
The RCR is equipped with the SHIMANO 105 DI2 R7170 complete groupset and INPEAK power sensor. A power meter is a must for cyclists who want to plan their training to help them improve.
The electric groupset has two separate batteries (one for each derailleur). You can use the Shimano E Tube app to set up your bike and track data from your rides.

Drive train maintenance
Please note that it is important to regularly service your drive train, especially if you ride in difficult conditions (wet and/or dirty roads).
Regular maintenance will help your drive train to last for longer.
You should regularly check your chain with our chain wear indicator,
which is available on our website.
Lifespan of a drive train
When buying a bike, it's important to take into account the cost of servicing it, especially as regards the drive train.
The amounts below are averages and are given so that you have a general idea of what to expect. They will of course vary depending on the care you take of your drive train.
The average lifespan of a well-maintained chain is 5000 km.
The average lifespan of a cassette is 10,000-12,000 km.
A poorly maintained chain can jump, which can damage your bike's frame.
Disc brakes
Shimano 105 disc brakes with RTCL800 160 mm discs at the front and 140 mm at the back.
The Shimano 105 brakes are hydraulic. This gives you progressive, more powerful braking than with cable-actuated hydraulic brakes.
You will need to bed these brakes in. Simply brake gradually 20 times at a low speed (20 km/h), then repeat at 30 km/h. Make sure to bed in both brakes.
Bedding in creates more friction between the disc and brake pad.
Hydraulic brake maintenance
Hydraulic brakes function using a closed circuit between your brake lever and your caliper.
There is a hose to maintain the seal.
With time, you'll see a normal loss of pressure in your hoses, leading to a loss of braking efficiency. When your brake guard is too soft, or you stop short against your handlebar, you need to bleed your system. This requires specific tools and knowledge.
Warning and adjustment
Please note: never squeeze the brakes without a wheel being attached, as you could get the brake pads stuck together.
If the rotor is touching the pads, here's how to realign the wheel and caliper:
- Loosen the wheel axle
- Brake hard and tighten the axle at the same time
- If the rotor is still touching the brakes, do the same thing and loosen the caliper
- If you're unable to resolve the issue, please visit one of our workshops.
SWISS SIDE HADRON CLASSIC 470 WHEELS
The SWISS SIDE HADRON CLASSIC 470 wheels are tubeless ready, hooked and designed to offer the optimal balance between riding durability and aerodynamic performance with 25 mm and 28 mm tubes.
Max recommended pressure: 7 mm
Weight per pair: 1600 g
CONTINENTAL GP 5000 S TLR TYRE
Ride faster, more comfortably and with even greater puncture resistance with the Continental GP5000 S tubeless ready tyres
700x28C: pressure between 4 and 6.5 bar
280 g
Tubeless or inner tube
We recommend switching your tyres to tubeless using the tubeless valve that comes with this bike.
Tubeless is more comfortable and more efficient, and the tyres can self-repair when you get small punctures.
Of course, you should always carry an inner tube in your repair kit, just in case your tyre gets a slightly bigger puncture.
Position
-15 mm RCR carbon seat post
140 mm Decathlon road light saddle, the saddle has a short nose to promote stability and relieve pressure on the soft tissue area.
Weight: 250 g
Pedals
Sold without pedals
Which size?
Please refer to the bike frame geometry table.
If you're between sizes, a shorter bike is better if you want something more responsive and lively. However, if you want to be comfortable when riding long distances, the bigger size is your best bet.
