Aspero Frameset engineered for speed with adjustable geometry and wide clearance
What Our Gearhead® Experts Are Saying:
"The Aspero frameset feels like a purebred race platform—quick acceleration, sharp cornering, and geometry that stays composed when gravel gets chunky. The T47a bottom bracket adds stiffness for power transfer, and the TrailMixer dropout setup really works for dialing in handling between wheel sizes. It’s an incredibly versatile starting point for building a high-performance gravel bike."
Cervelo’s Aspero Frameset establishes a race-focused foundation for riders seeking maximum efficiency across diverse gravel terrain. The all-carbon frame and tapered fork maintain the responsive handling characteristic of performance road machines, while the gravel-specific geometry increases stability by shifting rider weight slightly rearward. A longer top tube and shorter stem reduce toe overlap, improve front-end control, and create a stable position for descending loose or technical segments at speed.
With clearance for 700 x 45c or 650b x 48c tires, the Aspero adapts easily to rider preference and terrain type. Cervelo’s TrailMixer dropout system adjusts mechanical trail to preserve consistent handling when switching between wheel sizes, keeping steering feel balanced regardless of setup. The T47a bottom bracket maximizes stiffness and power transfer, while internal cable routing and a bolt-on front derailleur mount keep the build clean and compatible with modern drivetrains.
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. If you want to double-check the details, our Gearheads are always here to help.
Three bottle mounts, top-tube bento compatibility, and dropper-post readiness expand its capability for long-distance racing or adventure riding. Whether built for gravel events, fast mixed-surface loops, or multi-day exploration, the Aspero offers the technical precision and versatility needed to create a custom, high-performance gravel machine.

Frequently Asked Questions
Does the Cervélo Áspero Frameset use a threaded bottom bracket and what crank standards fit?
The Áspero uses a T47a threaded BBright shell (user-serviceable) and is compatible with SRAM DUB Wide spindles, avoiding press-fit issues common on some gravel frames.What wheel and tire sizes will the Cervélo Áspero Frameset accept?
The frame uses trailmixer dropouts that accept either 700c or 650b wheels and offers wide tire clearance—compatible with tires in the ~50mm+ range and designed for tubeless setups.Is the Cervélo Áspero Frameset dropper-post compatible and what seatpost size does it take?
Yes—it's dropper-post compatible and spec'd with a Cervélo SP19 carbon seatpost at 27.2mm diameter.What headset, fork, and steering features come with the Cervélo Áspero Frameset?
The Áspero ships with a tapered all‑carbon Áspero fork and supports FSA IS2 1-1/4 x 1-1/2" headsets (newer builds may use Cervélo's ST36 semi‑integrated system); the steerer and semi‑integrated routing are optimized for tidy hoses and aero gains.What brake, axle, and derailleur standards does the Cervélo Áspero Frameset support for a modern gravel build?
It uses flat‑mount disc brake mounts, Cervélo aero thru‑axles (12x100mm front, 12x142mm rear), and a UDH‑compatible derailleur hanger (SRAM Transmission/12‑speed friendly), so it’s ready for hydraulic GRX/SRAM setups and modern 1x or 2x drivetrains.
