The RT9 is designed for experienced riders who prioritize low weight, climbing performance, and premium carbon engineering. It is ideal for cyclists who spend long days in the mountains and want highly responsive, race-level equipment.
Its performance-focused geometry and lightweight construction are intended for serious training, racing, and riders who value efficiency over a relaxed riding position.
Yes. The RT9 arrives partially assembled and can be completed using the written assembly guide and assembly video.
Because the RT9 uses advanced carbon components and an integrated cockpit, correct alignment and torque are essential. If you are unfamiliar with bicycle assembly or do not have the appropriate tools, we recommend professional assembly and a complete safety inspection before riding.
The RT9 has a maximum total load capacity of 220 lbs (100 kg). This includes the rider and everything carried on the bicycle, such as clothing, water bottles, tools, accessories, and other equipment.
Exceeding the stated limit may affect handling, braking performance, and the structural integrity of the bike or its components.
Yes. The RT9 is available as a frameset for riders who want to create a custom build.
Other major RT9 components, including the integrated cockpit, Branta power-meter crankset, and wheelsets are also available for purchase. Contact an authorized X‑LAB dealer for current pricing and availability.
Most local bicycle shops can perform routine RT9 maintenance, including drivetrain service, brake adjustments, wheel service, and safety inspections.
For warranty claims, proprietary replacement parts, cockpit changes, power-meter service, or major customization, we recommend working with an authorized X‑LAB dealer.
The RT9 supports tires up to 30 mm wide. This provides room for modern road tires that balance speed, grip, and comfort while maintaining the bike’s lightweight, race-focused character.
Actual tire width can vary depending on the tire model, rim width, and inflation pressure. Always confirm adequate clearance around the frame, fork, and brakes after installation.
Yes. The integrated power meter can transmit live power data to most compatible bike computers and fitness devices through ANT+.
It can also connect through Bluetooth to the X‑LAB Bikes app for supported functions such as battery status, calibration, device information, and firmware updates. Live power data cannot currently be transmitted by Bluetooth directly to third-party mobile apps.
Yes. The RT9 frame is compatible with most wired and wireless electronic groupsets from SRAM and other major drivetrain manufacturers.
A groupset conversion may require compatible shifters, derailleurs, brakes, cassette, chain, crankset, freehub body, bottom bracket, wiring, and related hardware. A qualified mechanic should verify the complete parts list before installation.
Yes. The RT9 uses a Universal Derailleur Hanger, commonly known as UDH.
This standardized design makes replacement hangers easier to source and helps maintain consistent derailleur positioning. Following an impact, the hanger and derailleur alignment should be inspected before riding.
Yes. The RT9 integrated cockpit supports standard two-bolt, under-handlebar computer and combination mounts. A basic computer mount is included with the bike.
Before attaching a computer, light, or camera, confirm the mount’s load limit and use the correct hardware. Accessories should not be clamped directly to areas of the carbon cockpit that are not specifically approved for clamping.
The RT9 can accommodate up to a 55–42T configuration with a 2x drivetrain or up to a 68T chainring with a 1x drivetrain.
Compatibility depends on the selected drivetrain and components. Chainring clearance, chain length, derailleur capacity, and gearing compatibility should be confirmed by a qualified mechanic.
Yes. X‑LAB offers three size options for the RT9 integrated aero cockpit, allowing riders to select a configuration that better matches their fit and riding position.
Availability may vary. Because cockpit replacement can require disconnecting and rerouting hydraulic brake hoses, we recommend having an authorized X‑LAB dealer handle selection and installation.
Yes. The Branta carbon power-meter crankset is available in multiple crank lengths.
The appropriate length depends on the rider’s measurements, flexibility, pedaling style, fit, and intended use. An authorized X‑LAB dealer or professional bike fitter can help identify the best option.
Yes. In addition to the standard 52–36T chainrings, X‑LAB offers a compact 50–34T configuration and a race-oriented 54–40T configuration.
The compact option provides easier climbing gears, while the larger option supports higher gearing for racing and fast riding. Although the chainrings use a standard 110 BCD pattern, their shape is designed to integrate with the Branta power meter, so compatibility should be confirmed before purchase.
Yes. Both the rims and original tires supplied with the RT9 are tubeless-ready, and tubeless rim tape is already installed.
Tubeless valves and sealant must be purchased separately. After conversion, verify that the tires are properly seated and remain within the pressure limits specified by both the tire and wheel manufacturers.
