Cervelo Aspero GRX RX815 Di2 Disc Gravel Bike 2023
The Cervelo Aspero GRX RX815 Di2 Disc Gravel Bike is made for fast off-road rides or races and makes great use of Cervelo’s long history of producing thoroughbred machines. The carbon frame is both efficient and comfortable so as not to waste a single watt but isolates the rider from tiring trail vibrations. A cutout in the seat tube allows the rear wheel to sit further forward for shorter chainstays and better handling whilst also providing it with some protection from the wind. Clearance for 42mm tyres on 700c wheels or 49mm if using 650b allows plenty of potential for wide rubber and the Trail Mixer flip-chip in the fork means that the geometry can be fine-tuned for the different wheel sizes if required.
Specifically designed for gravel use, Shimano’s GRX RX815 Di2 groupset has a smaller chainset than standard to better cope with steep off-road hills, with the electronic shifting making short work of swapping sprockets or chainrings even when under load. All-weather confidence and control are provided by the hydraulic disc brakes, and the carbon handlebar and seatpost from Easton add a further level of compliance and keep the weight down.
Light, stiff and reliable, the Reserve 32 wheels are tubeless-ready, with a carbon rim and DT Swiss hubs for a classy looking and high performance set up.
