Cervelo delivers the Aspero-5, with real upgrades in terms of reduced weight, greater lateral stiffness, increased emphasis on aerodynamics, and component grades, making it perhaps the purest gravel race model, with higher grade carbon fiber, a new lay-up schedule and major refinements that drive performance higher. Built here with Shimano's impressive 2x11 GRX Di2 drivetrain and hydraulic disc brakes, with an exciting Cervelo kit including Reserve carbon wheels, the Aspero-5 GRX RX815 Di2 Bicycle is performance built, right out of the box.

The Aspero-5 frameset retains the popular, proven Aspero geometry and Trail Mixer fork chip system, as well as an appearance with tube shapes that are largely the same. A closer inspection indicates a fully internal wiring and housing system, and a refined headtube. The Aspero-5 has the D-shaped fork steerer tube design seen on other 5-series bikes, which in combination with the included Carbon AB09 16° Flared Carbon Handlebar and Cervélo ST32 Alloy Stem, work with the steerer and the frame to bring the routing internal from the levers on back. An All-Carbon Tapered Áspero Fork with Adjustable Trail and headtube shape offer refined aerodynamics, enhanced by the internal routing. Not only is a completed bike visually clean- but faster. Cervelo's internal testing measures aero improvement at 32G of reduced drag over the standard Aspero.

Cervelo made some intelligent choices, such as carrying over the 27.2mm round seatpost, which offers the rider more options, including the opportunity to run a dropper post. The Aspero-5 includes the compliant carbon Cervelo SP19 27.2mm seatpost. Again, given this is a race-oriented bike, the frame and fork deliver clearance necessary for 650b x 51mm tires, or 700c x 43mm tires with at least 4mm on either side to spare. Cervelo is cognizant that for many of the longest, harshest events were capability and speed must be balanced with bike control, many racers will opt for 650b/27.5" wheels and may also want a dropper post.

The engineers were particularly focused on making sure the Aspero and Aspero-5 handled properly. Cervelo is using their Trail Mixer system to allow the rider to keep effective fork Trail at 62mm. Larger variations in tire size effect the rearward position of the tire- affecting handling and toe-overlap clearance. By using off center, bolt-in 12mm thru-axle drop outs, the rider can select the +5 forward position or the -5 rear position of the axle. With a 700x42 gravel tire set-up, the +5mm forward is the proper position for best active handling and nimble bike control. If you moved it to the -5mm rearward position, it would slow the handling down. Cervelo has a more complete explanation of the mechanically simple Trail Mixer system on their website so you can select your option based on tire size and handling preference.

What is amazing about geometry of the Aspero is that isn't road-like, but it feels like a more natural transition from a road bike than most gravel race designs. The handling speed and control are there, and the toptube measurements are longer, with the frame center of gravity pushed back a little, while a shorter length stem is used to control the front end. When you take it out on the road, perhaps to transition to your gravel access, the Aspero-5 won't feel awkward or uncomfortable, yet it will handle gravel and even twisty singletrack with aplomb.

Along with the bike, which includes the stem, handlebar and seatpost, Cervelo also adds several of their accessories, including the Stem Faceplate Computer/Accessory mount, Rear Accessory Mount, and Smartpak 400A Top Tube Storage Bag. A proprietary stem spacer kit is also included for minor set-up adjustments. In our decades of experience with Cervelo, the 5-series bikes have been well worth the upgrade for those looking for premium performance and refinement. The Aspero-5 offers measurable benefits these cyclists will embrace and apply to their fullest with this complete 2x11 GRX RX815 Di2 Bicycle.
