Build Overview
We’ve actually built this Cervelo Áspero several times over the years with different drivetrains, starting back during the COVID supply crunch. The original bike came as an Apex build, but the customer wanted Shimano GRX—and since parts availability was tight, we stripped the Apex kit and rebuilt it as an 11-speed GRX bike. Recently, the owner decided to upgrade it again, this time to 11-speed GRX Di2.
Because this customer’s family has multiple 11-speed Shimano bikes, sticking with 11-speed Di2 made the most sense. They can swap wheels and components between bikes without compatibility issues. We talked through 12-speed and even SRAM options, but ultimately 11-speed Di2 was the right fit for their setup.

Build Notes
This Áspero has a bit of a history with us. When the customer originally purchased the Apex build during COVID, they wanted GRX but supply was nearly nonexistent. We had GRX 11-speed mechanical in the shop, so we did a full drivetrain swap. Fast forward to now, and the request was to take that same bike and convert it to GRX Di2.
Because there’s still no Shimano GRX 12-speed Di2 (at least not yet), and the customer already has multiple 11-speed bikes in the family, staying with 11-speed was the logical choice. Wheel compatibility and parts sharing were important to them. We discussed moving to 12-speed or even SRAM, and while I love SRAM’s 12-speed stuff, the 11-speed GRX Di2 hoods and ergonomics are fantastic—and familiar for this rider.
One part of this build worth noting: the original aluminum handlebar didn’t have Di2 ports, so we swapped it for the Cervelo carbon bar. It’s a bar we really like—narrower profile, clean internal routing channel, and it’s what comes on the Áspero-5 builds. I run this bar on my own Áspero-5 and have had a great experience with it.
Running full 11-speed Di2 wiring on a gravel bike is a bit of a process. Unlike Shimano’s 12-speed road Di2 (which is mostly wireless up front), the 11-speed Di2 system is fully wired: both shifters connect to junctions, the junction connects to the battery, and everything has to be tied together cleanly. It’s more wiring, but once it’s in place, it works.
One thing we’re always up front about with customers: if something you’re asking for doesn’t make sense for the bike, or there’s a better solution, we’re going to tell you straight. And if you’re unsure what direction to go, we’re good at looking at your bike, understanding your goals, and recommending the setup that will fit your riding best. This Áspero is a good example of that process—balancing rider goals, parts availability, compatibility, and personal preference.
