CerveloAspero
Origin
Launched in 2019 as Cervelo's first dedicated gravel bike, the Aspero was deliberately race-focused — a 'gravel S5' rather than a bikepacking-friendly do-everything machine. The flip-chip TrailMixer fork lets riders run 700c or 650b wheels without messing up the geometry, which became one of the platform's signatures. The second-generation 2024 redesign moved to a T47 threaded bottom bracket, modernised the semi-integrated cable routing, opened tyre clearance to 44 mm measured (45 mm ISO) on 700c and 47 mm on 650b, and stayed deliberately spartan on mounts — just a top-tube bag mount and one underside bottle ahead of the BB. It is the bike Lachlan Morton and other elite gravel racers reach for when the goal is outright speed, not comfort over week-long bikepacking days.

- Reserve 40|44 carbon (12×100 / 12×142 thru-axle) on upper builds; 700c standard with 650b option via TrailMixer flip-chip
The verdict
- Direct, efficient power transfer — feels like a fast road bike that happens to take gravel tyres
- Maintains speed effortlessly with the 2024 aero tube reshaping (~3 W faster at race pace)
- Versatile 700c/650b wheel swap via the TrailMixer flip-chip fork without upsetting geometry
- Surprisingly composed rear-end comfort for a race bike — dropped seatstays + 27.2 mm carbon post absorb buzz
- Clean, minimalist design with modern 2024 updates: T47 threaded BB, UDH hanger, fully-internal routing
- Race-focused mount strategy: only a top-tube bag mount and a single underside bottle bolt — poor for bikepacking/adventure loads
- Firm, precision-biased ride is less forgiving than plush all-day gravel bikes on rough terrain
- No truly top-spec flagship build offered on the standard Aspero — those chasing the lightest/fastest must jump to the pricier Aspero-5
- 45 mm tyre ceiling (700c) is tighter than many modern gravel rivals that clear 50 mm+
- Quick race geometry rewards experienced riders but can feel nervous/twitchy for newcomers at low speed
