Titanium comfort. Road-bike speed. All-road freedom.
The AR is an all-road bike designed to combine comfort with high-speed cruising, accommodating tires up to 40c.This frameset includes the titanium frame, headset, and carbon front fork.It offers the versatility to ride from paved roads to gravel while retaining the quick handling and efficient high-speed cruising of a road bike.The design balances titanium’s natural shock-absorbing qualities with light, agile handling.The AR is paired with a carbon fork featuring a 382 mm axle-to-crown length, shorter than typical gravel forks, giving it a more responsive road-oriented ride feel.Lightweight and highly resistant to scratches, the titanium frame makes an ideal touring companion.


Clearance for up to 40c Tires
The frame accommodates tires up to 700×40c, allowing a wide range of tire choices to suit your preferred ride feel.Combined with titanium’s natural shock-absorbing qualities, it delivers a smooth and enjoyable ride from paved roads to gravel, letting you explore without limits.


Multiple M5 Mounting Points
The frame is equipped with multiple M5 mounting bosses:2 on the down tube, 2 on the seat tube, 2 on the rear stays, and 2 on the top tube.
These mounts allow the installation of bolt-on top tube bags, as well as fenders—essential for group riding in wet conditions such as during long-distance brevet events.

Internal Cable Routing
All cables enter the frame from a single port beneath the down tube and are routed internally to the chainstay, keeping the exterior clean and uncluttered.The cable port on the down tube can be configured with different hole patterns depending on the number of cables used.A cable hatch on the BB shell allows cables to be routed from the down tube to the chainstay without removing the bottom bracket.





Modern Standards
The frame adopts the UDH (Universal Derailleur Hanger) standard, allowing the use of widely available derailleur hangers that are easy to source anywhere.The bottom bracket uses the T47 standard, combining the stiffness of a large-diameter BB shell with the convenience of a threaded bottom bracket for easy installation and removal.
