No track too far, no road too rough – the INISSIO GRAVEL guarantees unlimited riding thanks to its wide, grippy tyres and a high-quality carbon frame. Its optimally arranged carbon fibres minimise weight, maximise stiffness and ensure a high level of comfort. With many add-on parts available, the INISSIO GRAVEL can be configured fully equipped.


Sturdy, fast, all-terrain: As a crossover between cross and endurance bike, the Inissio Gravel road bike is incredibly versatile and a perfect companion for cross-country tours. Whether it’s on the road, on grass or on gravel: With this allrounder, you’re safe on all kinds of terrain – thanks to tyres that are up to 40 mm in width. Additionally, the gravel road bike offers you the possibility to mount mudguards, which turns it into an appealing option for commuters. A built-in rear rack makes the Inissio Gravel a great bike for travel as well. 


  • Tyres with up to 40 mm in width provide comfort and lots of grip for tours off paved roads. 
  • The flat-mount bracket on the Inissio Gravel allows for the best possible integration of the disc brakes. Good to know: Optionally, you can use a 180-mm disc in the front as well. 
  • Stainless steel protectors for the frame surrounding the chainstay and brake mount prevent dirt and stones from damaging the frame. 
  • The quick-release axles in the front and rear provide a high degree of stiffness and precise positioning of the wheel. 
  • And in general: The high frame stiffness gives the bike up to 100 percent steering precision and balanced handling. 


Just like its electric brother Inissio Pmax, the gravel model features state-of-the-art technology by Simplon as well. High-end at its best! If you appreciate a neat and clean look, you’ll love the Smart Headset. All cables run from the steerer directly through the headset down into the frame. At the same time, the Smart Headset also serves as protection for the cables. By the way, this two-wheel companion for longer journeys is uncompromisingly comfortable too. The popular Comfort Concept allows for a relaxed sitting position. That’s facilitated by special flattened tube cross-sections on the seat stays and chainstays, seat post, top tube as well as the seat tube. Higher vertical flex as well as comfort at the fork are possible thanks to the Raptor Dropout technology – rear-facing dropouts. A huge benefit for all those who love to head out into rough terrain! 


Listen up, commuters and bike travellers! Mudguards, rear rack, light – with these upgrade options, you’ll stay safe on the road. The Inissio Gravel would definitely pass the everyday-life test with these. Additionally available: wheels with tyres of up to 40 mm in width.
