Aspero-5

The Aspero-5 sits above the standard Aspero as the CFR-equivalent gravel race flagship — same race-focused DNA, but with aerodynamic shapes lifted directly from the S5 aero road platform and a significantly lighter, stiffer layup. The 2025 update goes hard on speed claims: Cervelo says the new Aspero-5 is 37 watts faster than its predecessor and 34 watts quicker than the nearest competitor (at 45 km/h in a wind-tunnel context). The rear dropout moved to SRAM UDH for full compatibility with the latest XPLR full-mount derailleurs. Tyre clearance stays a relatively modest 45 mm — deliberately so, because this bike is built for fast smoother gravel like Unbound or SBT GRVL, not technical singletrack-adjacent terrain. The aero SP27 seatpost prevents dropper-post fitment, underlining the road-leaning intent.
