Cervelo Aspero-5 GRX RX815 Di2 Disc Gravel Bike 2022
Blending a sophisticated, full carbon frame with top-spec components, the Cervelo Aspero-5 GRX RX815 Di2 Disc Gravel Bike delivers speed and efficiency across all manner of terrain during the biggest adventures and most challenging races.
The frameset comprises the finest carbon to be light, laterally stiff and comfortable, delivering a reactive, agile and composed riding experience. The tube shapes are optimised via advanced computer software to increase aerodynamic efficiency, helping the rider save energy when battling relentless headwinds. Entirely hidden cables and brake hoses further lower drag and donate a super clean aesthetic to the bike's front end.
Either 700c or 650b wheels can be used in the frameset, allowing the ride characteristics to be fine-tuned in line with different terrain. Innovative TrailMixer fork tabs alter the wheelbase so that the handling is always balanced, regardless of the wheel size being used.
Reserve carbon wheels are light, robust and have a 24mm internal rim width to support wide tyres over rough riding surfaces. These wheels are driven by the Shimano GRX815 Di2 electronic, double chainring gear configuration that shifts flawlessly through a vast range of ratios. Hydraulic disc brakes complete the build, offering reliable, easily modulated stopping power in all conditions.
