A FEW THINGS TO KNOW ABOUT THE GCR SRAM
Your GCR comes with a box that includes:
- Traditional pedals: we recommend the use of clipless pedals to get the most from your bike.
- 1 bottle of tubeless preventive sealant for both wheels + the tool to tighten/loosen the valve.
- 2 hydraulic brake blocks (the second is mounted on the bike in the original packaging).
- 1 bike bell
- 1 front and rear light.
- 1 torque wrench.
SRAM SHIFTERS AND DERAILLEUR BATTERY
The derailleur battery and SRAM charger are provided with the bike. SRAM says that the battery will last about 20-40 hours (500-1000km) and we recommend that you fully charge it before using your carbon gravel bike for the first time.
We recommend recharging it at least once a month.
The shifter batteries are directly integrated by SRAM and synchronized with the derailleur during assembly, so you don't have to do anything.
BIKE QUALITY ASSURANCE
Quality is in our DNA!
Each bike is fully assembled on a stand by the same person at our B'Twin Village plant in Lille, France.
Each person is committed to ensuring the quality of every bike they assemble.
For example, each screw is tightened with a connected torque wrench that provides very detailed quality monitoring (recommended and actual tightening torque, who does it and when). You will have access to these data from the first quarter of 2023.
Hydraulic disc brakes
This carbon gravel bike comes with SRAM Rival hydraulic brakes. We chose this system because the braking power provided by the hydraulic disc brakes allows you to perfectly control your bike and adds steering comfort in all conditions. No need to force your brakes to slow down: braking is smooth, progressive, and precise!
● Front disc: 160 mm
● Rear disc: 160 mm
CONTINENTAL TERRA SPEED TYRES FOR HIGH PERFORMANCE
We chose to equip our carbon gravel bike with Continental Terra speed 700 x 40 mm tyres for their performance and flexibility. Originally installed tubeless, you'll need to add the sealant provided with the bike yourself. The even, grippy design of this tyre excels on dry ground, but is not recommended on very wet terrain.
The sidewalls are reinforced to help the tyre withstand impacts and stones.

Care tips
We recommend avoiding high-pressure water jets when washing your carbon gravel bike to avoid damaging it. We recommend cleaning your GCR SRAM after each ride, particularly after confronting particularly muddy or dusty terrain. In addition, remember to check your tyre pressure and braking efficacy before each ride.
CHOOSING THE SIZE OF YOUR GCR
We designed this frame to fit the following heights:
Size S: 156/170
Size M: 168/180
Size L: 178/190
Size XL: 188/200
If you're between two sizes, base your choice on your preferences. Looking for compactness, responsiveness, weight and a certain look? Choose the smaller size.
Stability and comfort (back, neck)? Opt for the larger size.
The Reach value (find on photo geometry chart) is important to consider in relation to your personal measurements.

FULCRUM RAPID RED 900 WHEELS: PERFECTLY ADAPTED TO OFF-ROAD RIDING!
The versatile, durable Fulcrum Rapid Red 900 aluminium tyres on our gravel bike are also tubeless ready, with 28 spokes and an internal width of 22 mm. Ride with confidence on all types of terrain, rest assured that irregular terrain will be properly absorbed for your greatest comfort!
MAXIMUM CLEARANCE FOR TYRES
The maximum size for tyre width is 42 mm.
TUBELESS ASSEMBLY FOR GREATER RELIABILITY AND PUNCTURE RESISTANCE
The wheels are set up as tubeless, but come WITHOUT SEALANT!
You'll need to add the sealant directly into the valve, after deflating the tyre and removing the valve cap. Note that the bottle of sealant provided with the bike is enough for both tyres (60 ml of product per tyre). To finish, fully tighten the valve cap and reinflate the tyres to the desired pressure, between 1.8 and 3 bars maximum.
FOCUS ON THE HANDLEBAR AND STEM
Our carbon gravel bike is equipped with an oversize aluminium ERGO handlebar with a 16° flare, meaning the angle between the vertical part and the side of the handlebars. For a size S, the width of the handlebars will be 400 mm, for a size M/L, the width of the handlebars will be 420 mm, and for a size XL, 440 mm.
For our carbon gravel bike, we opted for an oversize ERGO aluminium stem. Here is the stem sizing in detail:
● S: 80 mm
● M: 90 mm
● L: 100 mm
● XL: 110
