Key benefits of the Orbea Onna 40

• SR Suntour XCT 30 fork: With 100 mm of travel and a coil spring, it effectively absorbs small bumps and roots on forest trails.
• Shimano Cues U4000 rear derailleur: The 9-speed system with an 11–46T cassette provides a wide gear range for tackling steeper climbs without excessive effort.
• Shimano MT200 brakes: Hydraulic disc brakes deliver consistent stopping power in all weather conditions, increasing safety on descents.
• Kenda Booster 2.40″ tyres: The wider profile on 27.5-inch wheels provides excellent grip and extra cushioning on gravel and dirt.

Out on the trails

On forest climbs, the 9-speed Shimano Cues system and 32-tooth chainring make it easy to pedal smoothly and find the right cadence, even on steeper sections.

On all-day gravel rides, the relaxed geometry of the aluminium frame reduces fatigue in your back and shoulders, while the wider 2.40-inch Kenda Booster tyres provide a comfortable contact with the ground.

On easier descents, the Shimano MT200 hydraulic brakes and 100 mm of travel from the SR Suntour fork provide a calm, controlled ride over small obstacles and bumps.
