The Orbea Avant is an aluminium endurance road bike built for comfortable long days, sportives and year-round riding. Its relaxed geometry, carbon fork and room for 30c tyres make it a confident, versatile choice for newer and experienced riders alike.
The H45 1X keeps things simple with a single 40t chainring and a huge 11-50t Shimano CUES 11-speed cassette, so there's no front shifting to think about. Shimano RS405 hydraulic disc brakes give consistent stopping in all weathers.
