Bianchi Arcadex GRX600 1x Disc Gravel Bike 2022
Bianchi's Arcadex GRX600 1x Disc Gravel Bike is designed for fun and speed off-road, drawing on the brand's many years of race bike experience.
The carbon frame and fork are responsive and quick, with clearance for 700×42c or 650×47c tyres so that the bike can be set up to match the terrain. There are eyelets for mudguards and attachment points for extra bottle cages and a bento box for longer excursions whilst the frame design is both efficient and comfortable.
Shimano’s GRX 600 groupset has been designed specifically for gravel riding and utilises a single front ring paired with a wide-range 11-42 cassette to give plenty of ratios for off-road conditions. The GRX level hydraulic disc brakes borrow features such as Servo Wave from the MTB line to make it more suitable for use on dirt and gravel. Tough, tubeless-ready wheels and tyres allow the bike to be run with lower pressures for better grip and comfort along with reduced puncture risk. Also gravel-specific, the handlebar features a 16° flare for greater control when things get rough.
