GRAVEL

SERVICE GRAVA

A faster, lighter, and more aero gravel race machine, designed to stoke your competitive fire. 

SPEED THAT GOES ANYWHERE.

When your quest for speed goes beyond the pavement, the Service Grava lets you explore your potential. We built the ultimate gravel race bike by making it faster, lighter, and more aero than the competition, with the tire clearance and confident handling athletes need to take control on rough terrain. 

MORE CONFIDENT HANDLING

Going fast on loose surfaces requires confidence. The Service Grava geometry and handling maximize confidence by balancing the stability to plow through rough gravel descents with the agility to make instant line changes and rail loose corners.

MORE TIRE CLEARANCE

The Service Grava is designed to take advantage of the fastest gravel tires on the market by fitting 56mm gravel or 2.2” MTB tires front and rear to enhance speed, comfort, and puncture protection while maintaining clearance for mud and debris.

MORE SPEED & DISTANCE

Optimized frame and fork aerodynamics meet low frame weight and fine-tuned compliance to create the most efficient and comfortable gravel package possible. Extra mounts increase carrying capacity for epic race days and all-day adventures.

BUILT FOR COMPETITION

 EXPLORE YOUR POTENTIAL

In the battle for gravel supremacy, Quintana Roo engineers knew exactly what it would take to succeed. The Service Grava is built from the ground up using aero framebuilding knowledge acquired through decades of race wins. For athletes who desire speed on any surface, it’s designed to provide every advantage possible. 

    MADE FOR THE FASTEST TIRES

    Tire clearance is at the forefront of the Service Grava’s design, with the frame, fork, and geometry made to perform with extra-wide gravel and XC MTB tires. 56mm of clearance gives athletes more options to optimize tires to suit their terrain, event, or preferences. 

    AERO FRAME & FORK SHAPING

    The Service Grava improves efficiency in the wind with aero tube shapes designed for wider gravel tires. An ultra-wide stanced fork profile promotes clean airflow between the fork blades and front wheel, helping airflow pass smoothly over the ultra-wide aero downtube. 

    LIGHTWEIGHT CARBON CONSTRUCTION

    With the same advanced carbon construction techniques as our championship-winning bikes, the Service Grava is built lighter than much of the competition while retaining the ruggedness needed for off-road riding. 931g (size M) frame weights allow for lightweight builds. 

      ULTRA CONFIDENT HANDLING

      The Service Grava geometry is tuned to maximize confidence on loose gravel and dirt roads. Increased reach improves high-speed stability and traction, while the restrained head angle and progressive fork rake maintain agility for responsive handling on technical terrain.

      MORES MOUNTS FOR FUEL & SPARES

      More mounts mean bottle cages can be positioned to carry larger bottles or to fit three bottles inside the main triangle. Additional mounts on the top tube and under the downtube provide options to carry more nutrition and supplies during ultra-endurance epics. 

      BOMB-PROOF STANDARDS

      The future is unknown, so the Service Grava is built with reliable standards. A UDH (Universal Derailleur Hanger) means easy replacements and compatibility with full-mount derailleurs. A threaded T47 bottom bracket provides stiffness and easy serviceability for home mechanics.

      QUINTANA ROO GRAVEL

      A NEW ARENA

      Gravel means freedom, and the Service Grava is the bike that gives you more freedom to go where you want. Discover roads beyond the horizon, explore the edges of the map, and go beyond the limits of your fitness. The Service Grava will maximize your potential, no matter how you choose to ride.

      The Service Grava is our lightweight gravel race bike, built for riders seeking a competitive advantage for high-performance riding. It uses a lightweight frame with aero shaping and geometry tuned for both agility and control, making it perfect for high-speed endurance gravel riding and racing.

      Yes. The Service Grava comes with tubeless-ready wheels and tires and is shipped set up tubeless with sealant from the factory.

      Yes! The Service Grava is also fast and efficient on the road. If you choose to install road tires on your Service Grava, we recommend using tires at least 700c x 38mm wide to minimize the effect smaller tires will have on the geometry. 

      The Service Grava's 1x chainring max is 44t (@ 47.5mm chainline) or 2x chainring max is 48/31t (@ 47mm chainline)

      The Service Grava frame fits tires up to 700c x 56mm* wide (equivalent to a 2.2" MTB tire) in the rear triangle with a 1x drivetrain. Clearance is limited to 700c x 49mm* with a 2x drivetrain, due to clearance limitations of specific electronic front derailleurs.

      The Service Grava's Fork fits tires up to 700c x 61mm* (equivalent to a 2.4" MTB tire).

      *Tire clearance will vary depending on your specific tires and wheels.

      The amount of assembly required depends on shipping option you select. Typically our bike assembly runs between 30 to 45 minutes. Check out our shipping and delivery options to find the best option for you and your budget.

      We spec different length components on our bikes based on common lengths per each size of bike. If you are looking to specify what length components or the gearing you'd like on your new Quintana Roo just live-chat or contact us and we'll get you started on a custom order.

      Absolutely. Our bikes are built to order so you can customize however you'd like. If there are components you'd really like on your bike but don't see them offered live-chat or contact us for availability and a custom quote!
