Specialized Aethos Expert Disc Road Bike 2022
The Specialized Aethos Expert Disc Road Bike comprises the brand’s FACT 10r carbon that’s laid in a sophisticated format across traditional round tube sections to deliver exceptional lateral stiffness, low weight, strength and a classy aesthetic. Additionally, the lateral stiffness is perfectly blended with precise levels of vertical compliance across the front and rear of the frameset to grant a balanced and poised sensation, while a race-inspired geometry positions the rider powerfully over the pedals. These frameset traits combine to promote a stunning ride character that surges up climbs and descends on rails during hard-fought group rides to the favourite café stop.
Roval C38 wheels are light, aerodynamic and stable in crosswinds and can be dressed in plush, grippy, 32mm wide tyres when the road surfaces are poor, thanks to the frameset’s generous amounts of clearance. Driving the wheels, the Shimano Ultegra R8100 gear setup shifts flawlessly every time of asking via its sophisticated semi-wireless, electronic configuration. Hydraulic disc brakes take care of the stopping duties, performing with admirable levels of power and control, even during inclement weather.
