Cervelo built the Cervelo Aspero-5 GRX Di2 Bike with one goal: to be the fastest gravel race bike on the planet. That's not marketing — the Aspero-5 debuted at the UCI Gravel World Championship, and Cervelo's wind tunnel data backs the claim: the updated frame is 37 watts faster than the outgoing Aspero and 34 watts faster than its nearest competitor. It's also 66 grams lighter than its predecessor, despite greater aerodynamic surface area throughout. When a faster bike is also a lighter bike, that's not a coincidence — it's the result of a complete aerodynamic and structural redesign from the ground up.

The Aspero-5 introduces a mixed tire geometry approach that gives riders a meaningful choice between two performance modes. Run equal-size tires — 42mm front and rear — for stable, confident handling on technical courses. Or run a 4mm differential (40mm front, 44mm rear) to optimize aerodynamic clearance at the front wheel while keeping traction at the rear, a setup Cervelo's aero team identified as meaningfully faster on open courses. The carbon Aspero-5 fork is engineered to accommodate either configuration within the bike's 45mm maximum clearance. The 422.5mm chainstay runs consistent across all six sizes, keeping handling character predictable regardless of frame size.
Internal downtube storage — borrowed directly from Cervelo's P-Series triathlon platform — adds functional real estate without disrupting the aerodynamic profile. Tools, a tube, CO2: it all disappears inside the frame. A Cervelo Smartpak top tube bag and front computer mount round out the on-bike storage system for longer efforts. This is a gravel race bike that can also handle a full day in the saddle without making you choose between speed and practicality.
The GRX Di2 build wraps the Aspero-5 carbon chassis in a component package that punches well above the bike's price point.
