The Cervelo Aspero-5 is a gravel bike built to lead the race from the front, and the GRX Di2 build carries that ambition through its cockpit as much as its drivetrain. Cervelo reshaped the front end around the HB16 handlebar and ST31 stem, a change responsible for nearly 6 watts of the frame's total aero savings compared to the standard Aspero. We paired the wireless GRX Di2 derailleur with an XTR cassette instead of stock GRX gearing, opening up a wider climbing range for gravel racing. A Wolf Tooth aero-profile chainring replaces the standard crank's ring, keeping the front end's aero gains intact even under power. What Our Gearhead(R) Experts Are Saying:"That 10-51T low gear got me up loose, punchy climbs I would've walked on a standard 1x gravel setup, and the wireless shifting never hesitated even caked in mud."Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive.
