Main advantages of the bike:
- Carbon frame
A monocoque carbon-fibre frame that provides top stiffness and low weight - 1280 g for the size S frame, 539 g for the fork. Internal cable routing contributes to an elegant and clean design. It is equipped with thru-axles for maximum stability and precise handling. For trips on gravel roads, the frame allows tyres of up to 50 mm in width.
- Optimised geometry
The frame geometry is designed as an ideal combination of comfort and performance, whether on long routes or technical sections. It provides confidence off-road, stability at higher speeds and efficient power transfer with every pedal stroke.
- Shimano GRX610 1x12 hydraulic groupset
The single chainring and the 12-speed Shimano SLX 10-51T cassette provide the maximum gear range and complete control over the ride. Precise shifting and reliability let you face any challenge with confidence. GRX610 brake calipers bite on 160 mm Shimano SLX SMRT70 rotors and deliver uncompromising braking power in every situation.
- TOKEN G23AR factory-built wheels
TOKEN tubeless-ready wheelsets combine lightness, stiffness and durability – an ideal companion for fast riding on any surface.
- Schwalbe G-One Allround tyres
Lightweight Kevlar tyres with Tubeless Easy technology offer perfect traction, durability and confidence over every kilometre of your journey.
- Supacaz Super Sticky Kush bar tape
Premium handlebar tape, favoured by cycling world champions. Its excellent grip and comfort at a thickness of just 2.5 mm make it an essential accessory for maximum riding comfort – even without gloves.
- Ritchey accessories
The seatpost, handlebars and stem from the top manufacturer Ritchey provide perfect ergonomics and durability that stands up even to the most demanding challenges.
This model combines cutting-edge technology and a passion for cycling in a single machine. It will let you overcome challenges, push boundaries and enjoy every ride to the fullest. Get ready to experience a gravel adventure in a completely new way!
