R.R275 X PRO
The fast beauty for any terrain
The R.R275 X is ROTWILD's first eGravel bike. It is both a homage to our roots in competitive sports and a clear statement of technical innovation and radical design. The "R" stands for Race. Experience the uncompromising pursuit of performance. Get ready for your next sprint. Always with the "X" in mind because we designed the bike for the detours. Off the asphalt, onto the forest path, right into the gravel. That's the freedom of gravel riding. You focus on riding. You value high reliability, stability, and clean design. With the R.R275 X, we share this intention. The focus is on your unique performance, and we support that with subtly consistent power, high functionality, and lightness. These elements are combined with a new design language: flowing lines, fully integrated lighting, and low weight make the R.R275 X a fast and agile beauty.
New design language
With the design of the R.R275 X, we have implemented a radical concept, working together with the design studio ARTEFAKT. We have translated the high functionality of the bike, the integration of electronic components, and a strong focus on athleticism into a clear design. All of this without any compromise on performance. The battery, motor, and display seamlessly blend into the frame, with the top tube and stem merging in a straight line. The enclosed taillight integrated into the frame marks the end of this visual line. This elongated appearance emphasizes strong dynamism, and the color segmentation underscores the design DNA and the core concept of top tube integration.
Boost Button
You can early identify the points on the road where your personal challenge lies. With the Boost Button, you get an extra dose of power. The button is almost invisible, integrated into the left side of the handlebars. You intuitively press it to receive up to 300 watts of extra power for up to 30 seconds. Specially developed software for the bike regulates the motor control. It maintains the perfect balance between your physical effort and the support from the bike. Choose one of the three assistance levels on the display seamlessly integrated into the top tube. Then simply stay on course. That's all you need.
Supernova light system
We use the Starstream by Supernova. The manufacturer designed this light exclusively for integration into the stem of a bike. The low beam shines with 550 lumens. A newly developed lens ensures glare-free illumination. You can adjust the beam distance using an adjustment mechanism. Activate your high beam with the smoothly integrated push button on the right side of the handlebar. It illuminates the dark path ahead with 1,000 lumens. A sensor in the display measures the ambient brightness and automatically turns the headlight on and off accordingly. The TL3 Mini taillight of the R.R275 X distinctly completes the top tube.
Integrated stem
By integrating the stem into the frame shape, we create a seamless connection between the steering and top tube. Two shells make up the stem. The lower one is directly connected to the head tube with a special ROTWILD aluminum shaping. We route the complete wiring for controls such as the Boost Button, brake, or high beam, as well as the cables for the display and control unit, through the stem and invisibly into the downtube of the frame. The upper shell secures the entire stem and serves as an interface for the wiring of the integrated Supernova light. With a taller lower shell, the entire stem can be raised by 2 centimeters.
IPU275 (Integrated Power Unit) - Motor
The TQ HPR50 motor, together with the battery and the Boost Button, embodies the concept of eAssist. The focus is on your own effort. The motor provides constant and subtle assistance. HPR stands for Harmonic Pin Ring gearbox. The absence of conventional gears and belts saves weight and allows for a compact motor design around the bottom bracket. By combining gentle support and lightweight construction, you maintain a natural riding feel even beyond the 25 km/h assistance limit. The HPR 50 provides you with up to a maximum of 50 Nm of torque and weighs only 1,850 grams. There are three levels of assistance available, which you can fine-tune using the TQ app.
IPU27 (Integrated Power Unit) - Battery
With an effective 250 watt-hours of energy, the battery provides you with all you need to continually extend your personal range with the R.R275 X. It seamlessly integrates into the slim downtube of the eGravel bike. Modern 21700-type cells allow for a lightweight and compact design. The intelligent energy storage system precisely delivers the predetermined amount of energy to the motor, effectively extending the battery's capacity. This enables pinpoint power assistance for different riding situations, optimized to provide you with maximum efficiency. The battery is ultra-lightweight at 1,400 grams.
XENTIS Gravel 2.5
In the Pro equipment variant, we opt for the XENTIS Squad 2.5 Gravel wheelset from the Austrian manufacturer XENTIS. The wheels are handcrafted from carbon. The 3K surface finish exhibits a very fine pattern. 2K matte lacquer protects the carbon surface and the wheel's decor from UV radiation. Each wheel has 24 spokes, making them extremely lightweight. The front hub width is 12-100 mm, and for the rear, it's 12-142 mm. The 28-inch wheels have a diameter of 622 mm and an internal width of 25 mm. The 25 mm rim height ensures high stability and balanced weight distribution.
Shimano GRX-gear shift
In the R.R275 X, in the PRO equipment variant, we have opted for the newly developed shifting components from the Shimano GRX series. This series offers you a 1x12 gear setup with a wide range and effective mechanics. This ensures a consistently high shifting performance on any terrain and during every one of your shifting actions. We use the GRX RD RX822 rear derailleur, which smoothly guides the chain through the gears. The integrated chain stabilizer keeps it tensioned in any riding situation, making the shifting very quiet.
Race-oriented geometry
Your posture on an eGravel bike clearly depends on the riding situation you find yourself in: streamlined for minimizing air resistance during descents or more upright to demonstrate agility on twisty terrain. The geometry of the R.R275 X sets the framework for these body positions. We have opted for a race-oriented approach, featuring a short head tube with greater saddle height, promoting an aerodynamic riding position on the bike. The tire clearance of the R.R275 X is 50 mm.
