Cervelo Aspero GRX 815 Di2 Disc Gravel Bike 2021
The Cervelo Aspero GRX 815 Di2 Disc Gravel Bike combines a design that targets raw speed with lightweight and accurate components to deliver adventurous riders across the trails, paths and tracks with personal best beating velocity.
The full carbon frameset has an aggressive, road racing-inspired character that is blessed with World Tour levels of stiffness and low weight to grant climbing prowess and punchy acceleration. In addition to the high stiffness to weight ratio, the frame’s tube sections sport aerodynamically tweaked profiles for lower drag at higher speeds.
The frameset is compatible with either 700c or 650b wheels and this adaptability combines with generous tyre width clearances to offer versatility for any off-road surface conditions. The geometry is balanced perfectly for efficient power transfer and composed handling and can be tweaked by using the Trail Mixer fork tab that refines the ride depending on the size of wheels being used and the terrain ahead.
Reserve 32mm, 700c wheels use their lightweight but robust full carbon rims that feature wide internal dimensions to offer a spritely but assured ride. These wheels are driven by the gravel-specific and highly accurate Shimano GRX 815 Di2 electronic gear setup. Braking is courtesy of the matching Shimano GRX RX815 hydraulic configuration that stops with power and composure whatever the conditions.
