THE DETAILS THAT MAKE THE DIFFERENCE
1. Comfort and nervousness: the perfect balance
The top tube incorporates a notable advancement in titanium frame engineering, based on three key optimizations.
It is hydroformed to offer variable geometry: wider at the junction with the head tube to increase frontal stiffness and steering precision, and narrower at the seat tube for better distribution of structural stresses.
It is also butted (stretched to variable thickness), with thinned walls in its center, allowing a significant reduction in weight while maintaining robustness at the stressed ends. This configuration also improves vibration filtration , contributing to smoother behavior on uneven terrain.
Finally, the tube is ovalized in the vertical axis, providing controlled vertical flexibility for better comfort, while increasing lateral rigidity . This technical compromise optimizes dynamic relaunches and control of the bike in the committed riding phase.
2. Mountain bike wheels
The Boost standard wheels (148/12 rear and 110/15 front) allow the installation of stiffer and stronger wheels, ensuring better control and increased durability even with a lot of weight on the bike.
3. More powerful brake mounts
The brakes are 180mm Postmount front and rear, compatible with drop bar or flat bar groupsets. We made this choice to allow the installation of four-piston calipers for more powerful braking. Framesets include Postmount to Flatmount adapters. The rear brake is integrated into the rear triangle for better protection. The frame is designed to work with carbon and titanium forks from 480 to 490mm in length, and its geometry is adjusted to accommodate 110/120mm suspension forks.
4. Smart integration and practicality
The integrated bearing headset allows for completely internal cable routing. The result: a cleaner cockpit, with no exposed cables, ideal for easily attaching bags to the handlebars. This also prevents the cables from getting caught on branches when riding in the forest.
5. Ergonomics, adaptability and sustainable performance
The GRAAVE is equipped with four mounting zones for bottle cages or accessories. Each zone is composed of three inserts as well as attachment points for luggage racks and mudguards, offering complete modularity.
Designed for use with our Gravel-specific handlebars and cockpits, the GRAAVE is compatible with the vast majority of stems and handlebars on the market.
6. Standard and scalability
AARNY uses a large number of standards to allow you to maintain and evolve it for many years.
The T47 format bottom bracket with internal bearings (86 mm) which offers optimal rigidity.
The upper and lower headset bearings are the same (40 x 52 x 7). They are easy to find and can be changed without tools, making maintenance and repairs easier. The wheel axles are 142 x 12 and 100 x 12 mm through axles.
The UDH Boost rear chainstay allows compatibility with the latest SRAM T-type derailleurs, allowing cassettes up to 10-52T. This standard also ensures the availability of UDH derailleurs worldwide.
The bike accepts tires with a maximum ETRTO clearance of 64-622 (29-2.5C) and a circumference of 2350 mm. The seatstays are asymmetrical to reduce chain slap, with integrated cable routing.
The 31.6mm seat tube is compatible with dropper posts, with internal cable routing. The seat clamp slot is reversed to facilitate pannier installation. There are numerous mounting points for bottle cages, panniers, and other accessories, providing great versatility for touring.
